My beautiful 5 year old lab, was diagnosed with lymphoma carsinoma 6 weeks ago, (given 2-3 months) I immediately asked my vet to put him on fenbendazol, he put him on 200mg/ml ( 7.5 ml daily) He weighs 65 pounds. I’ve been doing research on fenbendazol for a few months now and seeing promising results.
My vet (holistic) also put him on some Chinese herbs, but also put him on prednisone, as he stopped eating, I didn’t want to use prednisone but had to get him to eat. After a week I dropped the dosage to half as he wasn’t having a good reaction to it. He’s now on 12.5 mg daily. I’ve also weened him off his kibble to a raw diet with different vegetables and fruits. I started giving him Reishi mushroom extract daily and am starting to also give him turkey tail mushroom.
I’ve been reading a lot of different comments on what people have been doing.
I’m wondering if anyone can share some insight on the fenbendazol dosage? I’ve seen many different ones.
His appetite is great now but I think maybe from the prednisone?
He still loves playing and going for walks but tires faster than he did before.
We have an 18-ish year old rescue dog Radar, a 12 lb. Chihuahua/Italian Greyhound mix. He was diagnosed Dec. 2023 with an aggressive form of melanoma tumor inside his mouth, given 30-60 days without chemo, which we rejected. We have a traditionally trained younger DVM, with an open mind. Our vet did some research and gave us the dosage/protocol: 3 days on FenBen, 4 days off (brand name Panacur). He’s been on FenBen since Feb. 2024, has a great appetite, walks daily, and is happy. We are very pro quality over quantity, and so far so good. We’ve had rescues for 31 years so we usually know when “it’s time.”
Also, their dog food is critical.
We feed our two dogs DrHarveys.com Canine Miracle Health food with lean proteins and oils rotated. Lori Carscudden and Dr. Harvey will take your calls M-F 11-3 and answer any questions re: your pets, review lab results. They have helped us so much with nutritional guidance with several dogs over the years!

Hi Lettuce. It was 100% the ivermectin so be careful. She had been on prednisone for years off and off and never had such a terrible reaction.
She had very little response to Fenben.
I lost my little girl on 12/6/23. The lymphoma moved to her pancreas and she went within a couple weeks. I did take her to a Tesla bio healing center and she had great response - Walking and doing better than she had since it metastasized but I got her there too late. I spoke to the owner and learned that it takes about 3 months of bioenergy healing to change the events of cancer and I just got her there to late. I kick myself when I think that I could have taken her 3 years before and I believe I could have saved her. Since then I have done much research into energy healing and even now have a successful youtube channel with lots of alternative healing info that I'm learning. I hope that you will check it out. All my best to you and your beautiful baby.
So sorry for your loss. We all have regrets of “coulda, woulda, shoulda”, but you didn’t know then, but you do now. I had immense guilt for a similar situation and had to forgive myself.
I shared this with a friend of ours about 8 months ago after he announced a fundraiser for his dog, a 2 y/o German Shepard. He had been diagnosed with lymphoma. They were trying to raise $25,000 for his treatment. They went through with the treatment plan and a bout of sepsis occurred after a few weeks. He recovered temporarily and he just passed away at the end of August. So all that money for nothing. We have a 7 y/o female German Shepard. I recently asked our vet about switching her heartworm prevention meds to ivermectin. They’ve had her on a preventive called Interceptor. It’s a monthly medicine and quite expensive. The vet said it works for other parasites as well. So no to ivermectin. I do believe the vets, like physicians get a a kick back. No money to be made off ivermectin or fendbendazole.
My dog was adopted from a medical foster home who took her out of a kill shelter. She had had a litter of pups, kennel cough and adult heart worms. The medical foster group only treats dogs using the gentle treatment which is ivermectin. She had been treated for 4 months. It wasn’t supposed to kill the heart worms, just knock them back. When I got her I took her to the vet and she was heartworm free. Imagine that! Her weight went from 60lbs to 80, her desired weight. So ivermectin is also a miracle drug for our dogs.
I have a 6 month old puppy who has just been diagnosed with intermediate - high grade lymphoma with masses in his lung and abdomen. We are meeting with an oncologist tomorrow to discuss possible treatment options but I’m really keen to start him on fenben. I’m super unfamiliar with it all so wanted to just ask and see if anyone knows whether giving him fenben alone would be enough? Or if he would also require any additional medicines, e.g. turkey tail, milk thistle, cbd oil as well as what diet would best help to fight the cancer? He has been fed a high quality raw food diet his entire life as well as turkey tail so we are extremely shocked at the diagnosis.
I didn't notice any interaction but the efficacy began to wane and she began having breathing problems so I took her to the vet on July 14 and the lymphoma had moved to her sternum so luckily, our vet said to try l-aspariginase and mustargen which put her into remission again. We are holding everything but the prednisone right now and she's still in remission. Taking it one day at a time.
We didnt give her a second round of the asparginase and lomustine (ccnu - not mustargen) due to persistent diarrhea and the lumps came back in her belly and neck about 3 weeks after treatment. So we went back Monday and got another round of the asprginase and ccnu and the lumps are gone again plus no diarrhea this time so will are scheduled for another round on 9/5/23. She's on prednisone every other day also. Thankfully, we still have options at 3 years and 5 months from diagnosis. I will try the fenbendazole and ivermectin again if we run out of options but our oncologist has kept her alive and happy all of this time so going to ride it out as long as I can with her. One factor we hope will be a positive thing is that we just moved from a small trailer back into our home 11 months after hurricane Ian damaged it. She seems so much happier now and praying that being in her home again will decrease stress on her little body and mind. I'm still hopeful for more remissions or a cure. Don't give up guys. It's always been my contention that as long as she isn't suffering, the longer she hangs on, the more chance for a permanent cure.
So just an update on Miss Tillie. Last time, the dr only gave her the CCNU because she didn't want the risks and side effects of the asparginase. So she had only the CCNU the last time. When the vet first saw the multiple lumps that were on her belly, she was first concerned about mammary cancer but she did a sonogram and said they look like cysts. It appears she was right because there are more lumps on her neck which are not contained in the lymph nodes now. I did a little research and upped the prednisone to once a day which seems to have made the cysts either subside or get smaller which also supports the notion that they are cysts and not mammary cancer. Miss Tillie gets the CCNU one cap every 3 weeks and the lymphomas begin to flare up a bit about 4 days or so before her next dose but we are thankful that they do respond after a dose and we can keep this monster at bay. Our goal now is one more Christmas. I remember saying that 3 christmas' ago and here we are, now praying for her 4th Christmas which would put her at almost 4 years post diagnosis. Hang in there guys and while I am all about natural treatments, I'm certain that we would have lost our girl without our fabulous oncology vet.
I am so happy to find out that I can enhance and extend my pets life through your work and diligence. I have been taking FenBen for prophylactic purposes myself to prevent cancer. My husband was diagnosed with Follicular Lymphoma. He will get his last PET Scan report from the doctor tomorrow after a course of Chem (his decision). He had a clear scan after two Chemo treatments. If it is not the same tomorrow I plan to try to encourage him not to take more Chemo and try this. I have had chronic gastric issues all my life, nausea, diarrhea, bloating and discomfort constantly. Since I did Ivermectin cleanse and then started Joe Tippen's Protocol I have had absolutely no gastric issues, had tons of energy, no joint pains, and clear and sharp mind, all at 80 years old. I was on antidepressants off and on for years, but have not needed them at all since self treatments. Thank you for your wonderful site!
It is now the middle of June and our sweet pointer Daisy who was given 2 weeks to live in December is still with us 6 months later. We have had her on goat pancur 4 times a week and ivermectin twice a week. Though subdued she has remained happy and eating well and wagging her tail with no problems. However, in the last 3 weeks she has experienced much weight loss ( skin and bones) and seems to sleep much of the time. Something changed. We aren't quite sure what to do because she is in a different phase now. We stopped the Pancur for a couple of weeks to make sure it wasn't the medicine killing her appetite. She continued not to want to eat. We have now graduated to expensive special food and morsels attempting To get more calories into her. Having owned dogs for almost 70 years I've walked this road before, where you start getting more and more desperate and feeding them tastier and tastier your food from a spoon begging them to eat. So I'm under no illusion that she's going to live forever. She is 14- 15 after all even when she was diagnosed with hemangio ( sp) sarcoma last December 2022. I'm struggling with whether to continue the pancur and ivermectin now. I'm not sure it is going to make much difference and we want her to get maximum calories. From this point on we want her comfortable and loved. She has wildly exceeded her prognosis. I'm still very glad we have done the treatments since December.. Regardless of what the future holds
What is the dose of fenbendazole you're giving? Depending on that there may be beneficial suggestions to be offered. You can either respond here or by email at fenbendazole77@gmail.com
At first blush, it looks like the amount of fenben could be increased and the ivermectin dropped. Using fenben and ivermectin together is uncharted territory. That is, it may be interacting to cause the aphagia, etc. Just a thought. More info please.
Thx for putting this website together and making this collection of experience and information sharing available to all.
Also with a 40lb dog, 13.5 years, and 8 months post diagnosis, we are mostly relying on FenBen exclusively at this point. As you stated, mixing the two is unchartered territory. On days we tried IVM only, we noticed a rapid energy decline the following day, but stools were firmer. By day 3 back on FenBen, energy perks back up, but stools become liquid by the end of the day.
If we're after the parasites and their egg laying (creating more) by throwing FenBen at this, I'm wondering if (like with bacteria) there is not a tolerence building as at 2 to 3 grams per day, we're not seeing any curative/reversal of the tumor response.
Any new lit on IVM/FenBen combo you are aware of that could be shared?
Or should I attempt an uptick in FenBen to say a daily dose (I give the entire dose by splitting it into two, one for each meal) to a number beyond 3gms per day?
I have a 6.5 yr old l, 120lb male Doberman who was diagnosed with high grade lymphoma on 7/12/24. He was given 1-2 months to live. I gave him 3mg ivermectin (IVM) that day. The next day he couldn't eat or drink with his head down due to swelling in his neck and lymph glands, so I gave him 6mg the next meal and the next day the swelling was reduced enough to put his head down. I bumped him up to 9mg and then 12mg once a day. He was showing signs of improvement on IVM, but not alot in tumor/gland reduction. I decided to try Fenbendazole at 444mg 3 days, with 4 days IVM 12mg. I still wasn't seeing much tumor reduction, but he didn't act sick at all really and he ate his meals along with some raw meat. I looked up combining Fenben and IVM and determined it would be the most beneficial approach. I now give him 444mg Fenben with nighttime meal and 12mg IVM with morning meal. Today is the 4th day and I'm glad to report he has significant tumor reduction today. You would never know he was diagnosed with a deadly illness 1 month ago and should only have 1 month or less to live. At 2 months, we're going to take him back to the vet for blood work and aspirate of the glands. I'm curious of the vets response to his healing and we would like confirmation. FYI...he's had no prednisone, no chemo and no negative effects from the IVM or Fenben.
Our loved one passed this week, in our home and by our side.
Through the absolute desperation, as he no longer wanting food I had read some more about the combo FenBen (morning) and IVM at night as some have/had reported success.
I'm sorry to announce that ended poorly for us, but his passing on was not all that unexpected as we'd enjoyed a full 12 months of extra time together by putting him primarily on FenBen (dose: 1grm AM with food, 1grm PM with food, due to it's fat soluble nature.
Until enough literature and truly verifiable evidence presents suggest the two mix/work well in treating serious late stage cancers (spleen in our case) I do not recommend anything other than staying with just 1 form of treatment from the IVM/FenBen family.
It's been an absolute pleasure finding your site and all the great testimonies and supporting evidence.
Please keep up the great work in order to save/add quality life to our loving pets.
Thank you Ben Fen. With tears we let now 15 yo Daisy go on July 1, 2023.
Diagnosed with hemangiosarcoma of heart Dec 2022, given 2 weeks to live. Vet advised we love on her and she would hopefully die some night soon in her sleep. But For 5 months Daisy did very well with wagging tail, good appetite, short walks ( she had lost her formerly incredible stamina in past year) on fenben 6 ml ( panacur goat) , 4 x week and 2x week ivermectin dise for 40 lb dog. But in early June something changed profoundly and rapidly. Weight fell off of her. She refused food and slept almost all of the time. By mid-june her tail was curled up under her belly instead of wagging like usual. Suddenly she was skin and bones . And no matter what tasty morsels and special food we offered, she turned away. Her heart failure cough became more and more frequent and pronounced. I made an appointment with sorrow with the vet for today. But Friday night, 3 days ago something horrible must have happened inside her little body. By Saturday morning her gums were white, she could barely lift her head and it was clear that she was dying. Of course a Saturday and a holiday weekend, none of the 2 practices who had treated her were open.. By the afternoon she could no longer stand up or coordinate her movements. We ended up going to an emergency pet clinic. they were amazingly kind. We held her and whispered in her ear and she went quickly and peacefully. I don't at all regret giving her the fen ben protocol and the ivermectin. We and she got 5 really good additional months. She had very good quality of life until the final 4 weeks. Even in the final month when we all knew that this was the end, she mustered her strength one night and walked the quarter mile down the Hill with me to feed the horses. To her great delight she caught a skunk And got fully saturated!! So she was a happy girl!
So very sorry for your loss. Thank you, however, for relaying it here. Daisy sounded like an amazing girl. Your care for your fur-baby has likely saved/lengthened the lives of others’ best friends - all because you posted your experience & inspired others to try. 🙏🏻 to you and Daisy, ❤️❤️.
Thanks Renee and everyone else. Praying for everyone else's beloved pets to do as well as possible for as long as possible. So appreciative to all and FenBen
Our story. Miss Tillie, our chinese crested/yorkie mix was diagnosed with stage 4 lymphoma in April of 2020. She was given 30-90 days without chemo. We started her on traditional CHOP therapy. The lymphoma responded well and they stopped her first course early.
She stayed in remission for 5 months. We continued traditional chemo for 2 more remissions and during her 3rd remission, we believe she was given a rabies shot at a kennel, in spite of a letter from our vet saying that the vax could push her out of remission. In any event, we picked her up and she had lumps again. We took her back to our oncology vet and the only chemo that seemed to be working was the Doxorubicin so they gave it to her. Unfortunately, she had an anaphylactic reaction and it was her 5th dose anyway so she can not have the only chemo that really worked again. That one shot did put her back into remission for another 5 months.
After hurricane Ian destroyed our home, we had to move into a small trailer which I'm sure was stressful for her and she came out of her 5th remission. Since she couldn't have the Doxorubicin anymore, the vet started her on a newly approved drug called Laverdia. It was effective for just a few weeks so I started her on Ivermectin on December 26, 2022 at a very low dose and titrated her up. She was doing very well even when we stopped the Laverdia.
On April 1, 2023, she seemed to hit a plateau so I started her on Fenben 200mg/day (Shes only 8 lbs). I continued just the Fenben for about 2 weeks until April 21st when I switched her back to Ivermectin because the Fenben didn't appear to be as effective.
This time I increased the Ivermectin from 0.25mls to 0.3mls per day. After about 4 doses, she began to have neurological side effects. (shaking, jerky and unsteady). I discontinued the Ivermectin after the 2nd day of jerking and gave her a 3 day cleanout from all meds. The jerking and unsteadiness stopped.
She was acting like a pup this morning chasing the cat and barking like crazy but the lumps had more bruising and had increased a bit in size so this morning I put her back on the Fenben 200mg.
I am sooooo grateful for the 3 years we’ve gotten but I’m not going to give up on her and I am determined to try to cure this monster. My dilemma is whether to continue on the Fenben alone because maybe 2 weeks wasn’t long enough to see a response or to give her the Fenen with intermittent or daily doses of Ivermectin since it seems to work within days. Since they work by two different mechanisms, dual dosing may be the key,
I am a retired pharmacist and would love to review the mechanism of action of both drugs as well as the bioavailability if anyone has links. That’s the story of Miss Tillie’s lymphoma so far. I remember the day she was diagnosed. We were devastated but thanks to the “off label” uses of these drugs, we have had 3 great years with her. Don’t give up. I am confident that I can get her stabilized again. I don’t like giving anything but herbs on a long term basis but if it keeps our girl going and doesn’t severely affect her quality of life, I will continue it forever. Finding the appropriate dose is a challenge. BTW, she is on nutritional supplements as well - Sunrider Nuplus (a combo of herbs that my hubby and I take daily) with a mushroom complex, flax, and astragalus root.
Her diet is home made pescatarian because of the high omega 3’s in certain fish and because the evidence in the China Study (a human study) that cancer cells can literally be turned on and off by the content of animal protein. Since dogs are widely used in human studies, I decided to minimize her animal protein so every other batch I add salmon to her homemade food. Also of note, I have noticed that stress seems to be a factor in pushing her out of remission and daily walks/exercise seems to be beneficial in keeping the lymph system moving. I hope that some can benefit by our 3 year (so far) success fighting lymphoma and any input is greatly appreciated.
Hi Spirit. Miss Tillie She so very lucky to have you for family. That's incredible you have kept her going and happy for 3 years despite a very serious prognosis. Are you certain the neurological symptoms were from the ivermectin and not perhaps her disease going out of remission? Regardless I'm glad she's doing better again.
I have a little trouble finding all of the posts So I hope I am answering correctly in the right Box.
I'm sure you've seen my earlier post where I gave explicit dosages but I have to stress I'm making all of it up as I go as far as dosing. I would follow Joe Tippens as close as possible.
It sounds like you are much more organized with your dosing which is surely better. Since ivermectins half life is 3 .5 days I only give it twice a week . I use horse paste and I simply do it by weight As you would for a horse as described on the label. Since she is only 40 pounds however it's a tiny little dab, smaller than a pea, that I put on her food. I give her 6 ml of panacur goat wormer 4 days a week.i think I have read fenben half life is only 8 hours.
Ivermevtin on one of her " off" days and 1 day she gets both. She has not had a single side effect as far as I can see in the 5 months she's been dosed with these 2 medicines. I only began it as a last ditch try in Jan 2023 since she was diagnosed with hemingiosarcoma around her heart and vet gave her no more than 2-4 weeks. She was having seizure, stroke -like episodes with labored breathing before diagnosis.
Your Miss Tillie is so very tiny. I do not know what to suggest for dosing. 8 pounds is so different than 40 for figuring dosing. But you have given her 3 more years using your knowledge and instincts, so keep it up, and prayers for you and Tillie. Hope that helps. Daisy May 5, 2023 is still a happy girl, going on walks, eating well, wagging her tail. I hope the same for Miss Tillie
Hi Trying, thanks for your kind words. I'm so happy Daisy May is doing well. My heart goes out to you both. It's so sad that the vets can't prescribe these drugs for cancer. My oncology vet knows that Miss Tillie is getting them and says to keep going but since it's off label, she doesn't have much experience with it for cancer.
I feel very certain the neurological symptoms were due to the Ivermectin. She started the shaking about 3 days after I increased her dose to .3mls daily and stopped by the morning after I stopped it. She was on no other meds at the time and since it has completely stopped it’s not the disease progression. Also I did a little research afterwards and neurological side effects are well documented in the literature, mainly in Africa because they have had widespread use of Ivermectin decades after people in the US started using it.
I give the injectable Ivermectin orally to her because it much easier to control the dose than the paste. And I use the Safe-guard Fenben suspension. Its interesting that after posting, I did find a combination ivermectin/fenben product - Ivermectin 2% + Fenbendazole 20%, Oral Suspension so apparently we are not doing something that hasn’t been done before. It’s prudent to do the on/off schedule. I actually hadn’t checked the half life out on the drugs but I think I will give the Ivermectin every 3 days to restart and the Fenben daily to see if we get a response. Thanks so much for that!
I’m not sure which website I used to calculate the dose but I know it was a site online and it was for veterinary use but I will be sure to check out Joe Tippins site. I’m very thankful that I found this webpage and have the experiences of other people in the same situation to learn from.
You really should follow Joe Tippens protocol and others. I am just guessing basically but somehow she is still here. But i know you want to know. So...Daisy is 40 lb pointer. 4 days a week we put 1 teaspoonful of Safeguard liquid goat dewormer 10% suspension over her food. This = 6 ml of the oral suspension. I think the suggestion is now to do it 7 days a week but we've just stuck with 4 days a week. Then I put a tiny dab of ivermectin horse paste on her food twice a week. The tubes are calibrated to a 250 pound increments usually. So I try to do 1/5 of that which is basically a small dot smaller than a pea. I use the same dose recommended for most mammals. 91 mcg per pound. The papers I've read on both of these substances suggest they work in 2 different ways against cancer. Since I felt like we had nothing to lose, I went ahead and did both. It could be that Fenben by itself is just as good. As far as I can tell she has had 0 negative side effects. I began them a week apart so that if she did have a problem I could perhaps tell which medicine gave her the problem. But she had no problems.I will warn you, even armed with calculators and the instructions right in front of me, it gets very confusing figuring the difference of milligrams mg and micrograms mcg and grams g and milliliters ml and microliters mcl..mind blowing. My husband decided on the teaspoonful instead of syringe. She eats it readily on her food. I was concerned that if I made the dose even larger it might get to the point where she would begin to reject it. At this level she's still alive, she eats her food easily, and that's about the best we can do. Please keep me posted on your little furry creature. I'm so sorry you're having to come to this site. Again I pretty well made up the dosage Daisy is on and please understand that!
My 5-year-old dog was diagnosed with lymphoma last week, with every lymph node extremely swollen. Fortunately, I had been reading about fenben curing cancer in humans elsewhere on the web and researched the dosage info for dogs. Our veterinarian said the prognosis was 3-6 months without chemo (which he does not recommend). I talked to him about fenben and he said he doesn't think it will work, but to try it if I want. I gave our dog doses on Friday, Saturday, and Sunday. Today is Monday and the lymph nodes on his neck have reduced to about 1/3 of the original size. After each dose, there was significant reduction after only about two hours. I'm going to give him four days off and start another round. Hoping this continues!
Thanks for creating this substack. I'm loving the articles and comments!
One side is now down to 1/4 of the original size on Friday before fenben. I also started a higher protein diet, phasing out the kibble, but that has to be done slowly so they can adapt to the food change.
Our vet called a bit ago. He said he was amazed to hear what I said about the lymph nodes subsiding. He said "maybe we're onto something." I'm scheduled to stop by there tomorrow and will give him the address to this substack to check it out and fenbendazole.org.
My husband just got home from a trip and agreed that the neck nodes are way smaller. He also checked the nodes on his legs and said they are way smaller, too. He wants to bring our pup over for the vet to check tomorrow. My husband has known the vet for approx. 20 years. Vet has been in practice for approx. 50 years.
Some of the images we’re receiving involving visible tumor reduction in dogs is along the timeline of weeks not days. I was wondering if it is at all possible that your dogs “tumors” are actually pockets of parasite infestations? Don’t know if that’s even a possibility, just trying to account for the amazingly rapid response to fenbendazole.
The vet hasn't heard about it working, yet, but I think he will be shocked and in disbelief when he hears the result. He had called an oncologist friend who told him it wouldn't work and that settled it for him. Hopefully, he starts prescribing it to other patients in need. Dog continues to improve today: one neck lymph node is almost completely back to normal state. He seems fine except for sleeping more than usual, but I think that's just part of the recovery process.
How has it been going for you? My baby was diagnosed at the end of May. I had put her on the fenben for a couple weeks and took her off. She weighs 10 pounds and I started worrying I was giving her too much. She's on prednisone right now, but considering adding fenben back in the mix. How has your baby been doing?
She continues to be just fine. If I did not know she had a tumor around her heart, I actually would not know. I continue to treat her and I really don't have any way of knowing what is working, but something seems to be working. She has exceeded the predictions by several months now. First collapse Nov 22. "Two weeks to live" soon after Christmas. I am also not sure i am dosing her ideally. I am using the goat panacur liquid, 6 ml. I squirt it on her food. She is ~ 45 pounds and a 50 lb dose of ivermectin horse paste ( tiny bit). As long as she continues to have a good appetite, wag her tail, explore outside, act happy, i will continue. I am sorry about your sweet Sheltie. Don't have regrets, i know you did everything and your pup knew too.
I have a question. Are you giving therapeutic doses of BOTH Ivermectin and Fenben? I have only given 1 of them at a time for canine lymphoma and we are going on 3 yrs but she had a neurological reaction to the Ivermectin when I increased the dose. I stopped everything for 3 days but the lymphoma is coming back. I started the Fenben again today but it sounds like you are giving both which is what I've been considering. Thanks for your thoughts.
I'm sure it is written somewhere but I can't find it and I'm new to this site. For the canine cancer, is the dose the same no matter what size the dog is? I have a 40 lb dog. And do you give that dose every day from then on? Or do you give it for a set amount of time? My dog has Hemangisaroma on her heart. Just since last night I'm afraid she is in quite a bit of pain. I'm actually considering on euthanizing her today. But if this might help I'm willing to try. I just want to get it right. There's nothing to lose. Thank you
One idea is to go with 222 mg twice per day. The half-life of fenbendazole is around 8 hours, so splitting it up into two doses spaced 8 hrs apart will should help optimize the impact.
Just an update. Took my sweet doggy Daisy with the aggressive tumor on her heart to be euthanized yesterday because she was in terrific pain. We were all the way there in the room and I had signed the paper. The vet could see her acute pain and we had been warned that this would happen at the end. However he felt like something didn't look right. He found an enormous abscess inside her mouth! Lanced it and immediately Daisy normalized. We tore up the paper and I thanked them profusely and she is back home with me today. I will be getting FenBen. However I have a big question. When we discovered her aggressive cancer and we were told just to keep her comfortable, give her a few palliative care pills a day, and take her home, I started her on daily Ivermectin which also has been shown to kill cancer cells. I reread several of those iver cancer papers again recently just to make sure. It was the category of "might help can't hurt". I am a little concerned of adding Fenben to the mix. I found one paper comparing the two and it appears they work with different actions against the cancer cells. But I can't find where anyone has tried a combination of the two either in humans or animals. Has anyone else? But I also don't want to make some sort of toxic combination especially since I will be doing both of them daily. Has anyone else tried this for have any experience? By the way on the ultrasound yesterday of her heart the vet said it actually looked very good compared with two weeks ago. So that encouraged me about the Ivermectin possibly helping already. But who knows? Thank you
Just an update on sweet 14 yo Daisy. It has now been 6 weeks since she was given roughly 2 weeks to live. I am giving her Fen Ben 4 days a week, and Ivermectin about every other day. I'm just guessing at all of the doses. Who knows where the truth is but I can tell you she acts perfectly fine and perfectly comfortable. She does not have the stamina she used to have but other than that she is bright-eyed with a great appetite, wagging tail and no pain.
I have been wondering about giving my girl both Ivermectin and Fenben. We've had tremendous success keeping the lymphoma down with the Ivermectin but we just can't completely irradicate it and each time we stop the Ivermectin it seems to come back. How is your sweet daisy doing on both? Any side effects? Does it seem more successful than either drug alone?
Daisy is doing well still on April 17, 2023. Eats, plays, takes walks, wags tail. I still give her fenben 4 days a week and ivermectin 2x a week. Who knows? But we were told to take her home to die with a 2 week prediction back in late Decearly Jan
The case studies here indicate that fenben alone is all that’s needed. Other substances aka Tippen protocol, are not necessary. Prednisone mediates inflammation so it is most likely irrelevant to the anticancer effects of fenben.
That has not been my experience. Fenben was minimally effective. We have found for our girl's lymphoma, the Ivermectin has been very effective but she began developing neurological side effects so we are exploring a combo therapy
My beautiful 5 year old lab, was diagnosed with lymphoma carsinoma 6 weeks ago, (given 2-3 months) I immediately asked my vet to put him on fenbendazol, he put him on 200mg/ml ( 7.5 ml daily) He weighs 65 pounds. I’ve been doing research on fenbendazol for a few months now and seeing promising results.
My vet (holistic) also put him on some Chinese herbs, but also put him on prednisone, as he stopped eating, I didn’t want to use prednisone but had to get him to eat. After a week I dropped the dosage to half as he wasn’t having a good reaction to it. He’s now on 12.5 mg daily. I’ve also weened him off his kibble to a raw diet with different vegetables and fruits. I started giving him Reishi mushroom extract daily and am starting to also give him turkey tail mushroom.
I’ve been reading a lot of different comments on what people have been doing.
I’m wondering if anyone can share some insight on the fenbendazol dosage? I’ve seen many different ones.
His appetite is great now but I think maybe from the prednisone?
He still loves playing and going for walks but tires faster than he did before.
We have an 18-ish year old rescue dog Radar, a 12 lb. Chihuahua/Italian Greyhound mix. He was diagnosed Dec. 2023 with an aggressive form of melanoma tumor inside his mouth, given 30-60 days without chemo, which we rejected. We have a traditionally trained younger DVM, with an open mind. Our vet did some research and gave us the dosage/protocol: 3 days on FenBen, 4 days off (brand name Panacur). He’s been on FenBen since Feb. 2024, has a great appetite, walks daily, and is happy. We are very pro quality over quantity, and so far so good. We’ve had rescues for 31 years so we usually know when “it’s time.”
Also, their dog food is critical.
We feed our two dogs DrHarveys.com Canine Miracle Health food with lean proteins and oils rotated. Lori Carscudden and Dr. Harvey will take your calls M-F 11-3 and answer any questions re: your pets, review lab results. They have helped us so much with nutritional guidance with several dogs over the years!

Hi Lettuce. It was 100% the ivermectin so be careful. She had been on prednisone for years off and off and never had such a terrible reaction.
She had very little response to Fenben.
I lost my little girl on 12/6/23. The lymphoma moved to her pancreas and she went within a couple weeks. I did take her to a Tesla bio healing center and she had great response - Walking and doing better than she had since it metastasized but I got her there too late. I spoke to the owner and learned that it takes about 3 months of bioenergy healing to change the events of cancer and I just got her there to late. I kick myself when I think that I could have taken her 3 years before and I believe I could have saved her. Since then I have done much research into energy healing and even now have a successful youtube channel with lots of alternative healing info that I'm learning. I hope that you will check it out. All my best to you and your beautiful baby.

So sorry for your loss. We all have regrets of “coulda, woulda, shoulda”, but you didn’t know then, but you do now. I had immense guilt for a similar situation and had to forgive myself.
Where to go to see recommended dosage and timing of Ivm and fen for cats and dogs, please? My cat has lymphoma and weighs 6.2 pounds. Thanks!
I shared this with a friend of ours about 8 months ago after he announced a fundraiser for his dog, a 2 y/o German Shepard. He had been diagnosed with lymphoma. They were trying to raise $25,000 for his treatment. They went through with the treatment plan and a bout of sepsis occurred after a few weeks. He recovered temporarily and he just passed away at the end of August. So all that money for nothing. We have a 7 y/o female German Shepard. I recently asked our vet about switching her heartworm prevention meds to ivermectin. They’ve had her on a preventive called Interceptor. It’s a monthly medicine and quite expensive. The vet said it works for other parasites as well. So no to ivermectin. I do believe the vets, like physicians get a a kick back. No money to be made off ivermectin or fendbendazole.
My dog was adopted from a medical foster home who took her out of a kill shelter. She had had a litter of pups, kennel cough and adult heart worms. The medical foster group only treats dogs using the gentle treatment which is ivermectin. She had been treated for 4 months. It wasn’t supposed to kill the heart worms, just knock them back. When I got her I took her to the vet and she was heartworm free. Imagine that! Her weight went from 60lbs to 80, her desired weight. So ivermectin is also a miracle drug for our dogs.
I have a 6 month old puppy who has just been diagnosed with intermediate - high grade lymphoma with masses in his lung and abdomen. We are meeting with an oncologist tomorrow to discuss possible treatment options but I’m really keen to start him on fenben. I’m super unfamiliar with it all so wanted to just ask and see if anyone knows whether giving him fenben alone would be enough? Or if he would also require any additional medicines, e.g. turkey tail, milk thistle, cbd oil as well as what diet would best help to fight the cancer? He has been fed a high quality raw food diet his entire life as well as turkey tail so we are extremely shocked at the diagnosis.
How to get started?
Read this article. It shows you the dosage, etc
Sorry but which article- the article about what this owner did for this dog?
Put a safe-guard 2 gm pouch on kibble last night but that is much less than the dose recommended for my dog’s weight on the package.
Not thinking straight perhaps.
Unfortunately am also in middle of moving out of state- hectic!
I didn't notice any interaction but the efficacy began to wane and she began having breathing problems so I took her to the vet on July 14 and the lymphoma had moved to her sternum so luckily, our vet said to try l-aspariginase and mustargen which put her into remission again. We are holding everything but the prednisone right now and she's still in remission. Taking it one day at a time.
We didnt give her a second round of the asparginase and lomustine (ccnu - not mustargen) due to persistent diarrhea and the lumps came back in her belly and neck about 3 weeks after treatment. So we went back Monday and got another round of the asprginase and ccnu and the lumps are gone again plus no diarrhea this time so will are scheduled for another round on 9/5/23. She's on prednisone every other day also. Thankfully, we still have options at 3 years and 5 months from diagnosis. I will try the fenbendazole and ivermectin again if we run out of options but our oncologist has kept her alive and happy all of this time so going to ride it out as long as I can with her. One factor we hope will be a positive thing is that we just moved from a small trailer back into our home 11 months after hurricane Ian damaged it. She seems so much happier now and praying that being in her home again will decrease stress on her little body and mind. I'm still hopeful for more remissions or a cure. Don't give up guys. It's always been my contention that as long as she isn't suffering, the longer she hangs on, the more chance for a permanent cure.
So just an update on Miss Tillie. Last time, the dr only gave her the CCNU because she didn't want the risks and side effects of the asparginase. So she had only the CCNU the last time. When the vet first saw the multiple lumps that were on her belly, she was first concerned about mammary cancer but she did a sonogram and said they look like cysts. It appears she was right because there are more lumps on her neck which are not contained in the lymph nodes now. I did a little research and upped the prednisone to once a day which seems to have made the cysts either subside or get smaller which also supports the notion that they are cysts and not mammary cancer. Miss Tillie gets the CCNU one cap every 3 weeks and the lymphomas begin to flare up a bit about 4 days or so before her next dose but we are thankful that they do respond after a dose and we can keep this monster at bay. Our goal now is one more Christmas. I remember saying that 3 christmas' ago and here we are, now praying for her 4th Christmas which would put her at almost 4 years post diagnosis. Hang in there guys and while I am all about natural treatments, I'm certain that we would have lost our girl without our fabulous oncology vet.
I am so happy to find out that I can enhance and extend my pets life through your work and diligence. I have been taking FenBen for prophylactic purposes myself to prevent cancer. My husband was diagnosed with Follicular Lymphoma. He will get his last PET Scan report from the doctor tomorrow after a course of Chem (his decision). He had a clear scan after two Chemo treatments. If it is not the same tomorrow I plan to try to encourage him not to take more Chemo and try this. I have had chronic gastric issues all my life, nausea, diarrhea, bloating and discomfort constantly. Since I did Ivermectin cleanse and then started Joe Tippen's Protocol I have had absolutely no gastric issues, had tons of energy, no joint pains, and clear and sharp mind, all at 80 years old. I was on antidepressants off and on for years, but have not needed them at all since self treatments. Thank you for your wonderful site!
Fingers crossed for your husband.
It is now the middle of June and our sweet pointer Daisy who was given 2 weeks to live in December is still with us 6 months later. We have had her on goat pancur 4 times a week and ivermectin twice a week. Though subdued she has remained happy and eating well and wagging her tail with no problems. However, in the last 3 weeks she has experienced much weight loss ( skin and bones) and seems to sleep much of the time. Something changed. We aren't quite sure what to do because she is in a different phase now. We stopped the Pancur for a couple of weeks to make sure it wasn't the medicine killing her appetite. She continued not to want to eat. We have now graduated to expensive special food and morsels attempting To get more calories into her. Having owned dogs for almost 70 years I've walked this road before, where you start getting more and more desperate and feeding them tastier and tastier your food from a spoon begging them to eat. So I'm under no illusion that she's going to live forever. She is 14- 15 after all even when she was diagnosed with hemangio ( sp) sarcoma last December 2022. I'm struggling with whether to continue the pancur and ivermectin now. I'm not sure it is going to make much difference and we want her to get maximum calories. From this point on we want her comfortable and loved. She has wildly exceeded her prognosis. I'm still very glad we have done the treatments since December.. Regardless of what the future holds
Sorry to hear that.
What is the dose of fenbendazole you're giving? Depending on that there may be beneficial suggestions to be offered. You can either respond here or by email at fenbendazole77@gmail.com
At first blush, it looks like the amount of fenben could be increased and the ivermectin dropped. Using fenben and ivermectin together is uncharted territory. That is, it may be interacting to cause the aphagia, etc. Just a thought. More info please.
BenFen,
Thx for putting this website together and making this collection of experience and information sharing available to all.
Also with a 40lb dog, 13.5 years, and 8 months post diagnosis, we are mostly relying on FenBen exclusively at this point. As you stated, mixing the two is unchartered territory. On days we tried IVM only, we noticed a rapid energy decline the following day, but stools were firmer. By day 3 back on FenBen, energy perks back up, but stools become liquid by the end of the day.
If we're after the parasites and their egg laying (creating more) by throwing FenBen at this, I'm wondering if (like with bacteria) there is not a tolerence building as at 2 to 3 grams per day, we're not seeing any curative/reversal of the tumor response.
Any new lit on IVM/FenBen combo you are aware of that could be shared?
Or should I attempt an uptick in FenBen to say a daily dose (I give the entire dose by splitting it into two, one for each meal) to a number beyond 3gms per day?
Any days off recommended?
Thx.
I have a 6.5 yr old l, 120lb male Doberman who was diagnosed with high grade lymphoma on 7/12/24. He was given 1-2 months to live. I gave him 3mg ivermectin (IVM) that day. The next day he couldn't eat or drink with his head down due to swelling in his neck and lymph glands, so I gave him 6mg the next meal and the next day the swelling was reduced enough to put his head down. I bumped him up to 9mg and then 12mg once a day. He was showing signs of improvement on IVM, but not alot in tumor/gland reduction. I decided to try Fenbendazole at 444mg 3 days, with 4 days IVM 12mg. I still wasn't seeing much tumor reduction, but he didn't act sick at all really and he ate his meals along with some raw meat. I looked up combining Fenben and IVM and determined it would be the most beneficial approach. I now give him 444mg Fenben with nighttime meal and 12mg IVM with morning meal. Today is the 4th day and I'm glad to report he has significant tumor reduction today. You would never know he was diagnosed with a deadly illness 1 month ago and should only have 1 month or less to live. At 2 months, we're going to take him back to the vet for blood work and aspirate of the glands. I'm curious of the vets response to his healing and we would like confirmation. FYI...he's had no prednisone, no chemo and no negative effects from the IVM or Fenben.
Buford,
Per your comment: "looked up combining Fenben and IVM and determined it would be the most beneficial approach."
Can you direct me/us to the where you looked up the information?
Also as a month (roughly) has passed, how's your Doberman pup doing?
Tumor status?
Current protocol? Still on 444 FenBen nights, 12mg IVM days?
Thx.
Buford,
Please provide bi-weekly updates on status, progress, tumor, etc.
with a 40lb dog, I'll need to reconsider the quantities you're discussing for your 120lb pup.
Thx.
Greg
I concur with Ben Fen.
I would keep an eye on the IVM quantity as it has a 3.5 day 1/2 life and can make your pup dizzy/hard time with balance if he over doses.
Otherwise, keep up the good work.
Best
Very encouraging! Keep up the good work!
Ben Fen,
Our loved one passed this week, in our home and by our side.
Through the absolute desperation, as he no longer wanting food I had read some more about the combo FenBen (morning) and IVM at night as some have/had reported success.

https://www.2ndsmartestguyintheworld.com/p/synergistic-pairing-of-ivermectin
I'm sorry to announce that ended poorly for us, but his passing on was not all that unexpected as we'd enjoyed a full 12 months of extra time together by putting him primarily on FenBen (dose: 1grm AM with food, 1grm PM with food, due to it's fat soluble nature.
Until enough literature and truly verifiable evidence presents suggest the two mix/work well in treating serious late stage cancers (spleen in our case) I do not recommend anything other than staying with just 1 form of treatment from the IVM/FenBen family.
It's been an absolute pleasure finding your site and all the great testimonies and supporting evidence.
Please keep up the great work in order to save/add quality life to our loving pets.
Sorry to hear that.
Best wishes.
PS: How's his weight holding up?
My pup keeps losing weight and the tumor remains, but he's sustaining.
I'll reread your post for more tips on how to merge the two therapies together.
But as Ben Fen once stated, combining the two is unchartered territory at this point. I'll let Ben Fen jump in if he now has more info on the topic.
Thank you Ben Fen. With tears we let now 15 yo Daisy go on July 1, 2023.
Diagnosed with hemangiosarcoma of heart Dec 2022, given 2 weeks to live. Vet advised we love on her and she would hopefully die some night soon in her sleep. But For 5 months Daisy did very well with wagging tail, good appetite, short walks ( she had lost her formerly incredible stamina in past year) on fenben 6 ml ( panacur goat) , 4 x week and 2x week ivermectin dise for 40 lb dog. But in early June something changed profoundly and rapidly. Weight fell off of her. She refused food and slept almost all of the time. By mid-june her tail was curled up under her belly instead of wagging like usual. Suddenly she was skin and bones . And no matter what tasty morsels and special food we offered, she turned away. Her heart failure cough became more and more frequent and pronounced. I made an appointment with sorrow with the vet for today. But Friday night, 3 days ago something horrible must have happened inside her little body. By Saturday morning her gums were white, she could barely lift her head and it was clear that she was dying. Of course a Saturday and a holiday weekend, none of the 2 practices who had treated her were open.. By the afternoon she could no longer stand up or coordinate her movements. We ended up going to an emergency pet clinic. they were amazingly kind. We held her and whispered in her ear and she went quickly and peacefully. I don't at all regret giving her the fen ben protocol and the ivermectin. We and she got 5 really good additional months. She had very good quality of life until the final 4 weeks. Even in the final month when we all knew that this was the end, she mustered her strength one night and walked the quarter mile down the Hill with me to feed the horses. To her great delight she caught a skunk And got fully saturated!! So she was a happy girl!
So very sorry for your loss. Thank you, however, for relaying it here. Daisy sounded like an amazing girl. Your care for your fur-baby has likely saved/lengthened the lives of others’ best friends - all because you posted your experience & inspired others to try. 🙏🏻 to you and Daisy, ❤️❤️.
Thanks Renee and everyone else. Praying for everyone else's beloved pets to do as well as possible for as long as possible. So appreciative to all and FenBen
Our story. Miss Tillie, our chinese crested/yorkie mix was diagnosed with stage 4 lymphoma in April of 2020. She was given 30-90 days without chemo. We started her on traditional CHOP therapy. The lymphoma responded well and they stopped her first course early.
She stayed in remission for 5 months. We continued traditional chemo for 2 more remissions and during her 3rd remission, we believe she was given a rabies shot at a kennel, in spite of a letter from our vet saying that the vax could push her out of remission. In any event, we picked her up and she had lumps again. We took her back to our oncology vet and the only chemo that seemed to be working was the Doxorubicin so they gave it to her. Unfortunately, she had an anaphylactic reaction and it was her 5th dose anyway so she can not have the only chemo that really worked again. That one shot did put her back into remission for another 5 months.
After hurricane Ian destroyed our home, we had to move into a small trailer which I'm sure was stressful for her and she came out of her 5th remission. Since she couldn't have the Doxorubicin anymore, the vet started her on a newly approved drug called Laverdia. It was effective for just a few weeks so I started her on Ivermectin on December 26, 2022 at a very low dose and titrated her up. She was doing very well even when we stopped the Laverdia.
On April 1, 2023, she seemed to hit a plateau so I started her on Fenben 200mg/day (Shes only 8 lbs). I continued just the Fenben for about 2 weeks until April 21st when I switched her back to Ivermectin because the Fenben didn't appear to be as effective.
This time I increased the Ivermectin from 0.25mls to 0.3mls per day. After about 4 doses, she began to have neurological side effects. (shaking, jerky and unsteady). I discontinued the Ivermectin after the 2nd day of jerking and gave her a 3 day cleanout from all meds. The jerking and unsteadiness stopped.
She was acting like a pup this morning chasing the cat and barking like crazy but the lumps had more bruising and had increased a bit in size so this morning I put her back on the Fenben 200mg.
I am sooooo grateful for the 3 years we’ve gotten but I’m not going to give up on her and I am determined to try to cure this monster. My dilemma is whether to continue on the Fenben alone because maybe 2 weeks wasn’t long enough to see a response or to give her the Fenen with intermittent or daily doses of Ivermectin since it seems to work within days. Since they work by two different mechanisms, dual dosing may be the key,
I am a retired pharmacist and would love to review the mechanism of action of both drugs as well as the bioavailability if anyone has links. That’s the story of Miss Tillie’s lymphoma so far. I remember the day she was diagnosed. We were devastated but thanks to the “off label” uses of these drugs, we have had 3 great years with her. Don’t give up. I am confident that I can get her stabilized again. I don’t like giving anything but herbs on a long term basis but if it keeps our girl going and doesn’t severely affect her quality of life, I will continue it forever. Finding the appropriate dose is a challenge. BTW, she is on nutritional supplements as well - Sunrider Nuplus (a combo of herbs that my hubby and I take daily) with a mushroom complex, flax, and astragalus root.
Her diet is home made pescatarian because of the high omega 3’s in certain fish and because the evidence in the China Study (a human study) that cancer cells can literally be turned on and off by the content of animal protein. Since dogs are widely used in human studies, I decided to minimize her animal protein so every other batch I add salmon to her homemade food. Also of note, I have noticed that stress seems to be a factor in pushing her out of remission and daily walks/exercise seems to be beneficial in keeping the lymph system moving. I hope that some can benefit by our 3 year (so far) success fighting lymphoma and any input is greatly appreciated.

Great! Thank you. I might add add to my girls regimen again in a very low dose or periodic doses.
Hi Spirit. Miss Tillie She so very lucky to have you for family. That's incredible you have kept her going and happy for 3 years despite a very serious prognosis. Are you certain the neurological symptoms were from the ivermectin and not perhaps her disease going out of remission? Regardless I'm glad she's doing better again.
I have a little trouble finding all of the posts So I hope I am answering correctly in the right Box.
I'm sure you've seen my earlier post where I gave explicit dosages but I have to stress I'm making all of it up as I go as far as dosing. I would follow Joe Tippens as close as possible.
It sounds like you are much more organized with your dosing which is surely better. Since ivermectins half life is 3 .5 days I only give it twice a week . I use horse paste and I simply do it by weight As you would for a horse as described on the label. Since she is only 40 pounds however it's a tiny little dab, smaller than a pea, that I put on her food. I give her 6 ml of panacur goat wormer 4 days a week.i think I have read fenben half life is only 8 hours.
Ivermevtin on one of her " off" days and 1 day she gets both. She has not had a single side effect as far as I can see in the 5 months she's been dosed with these 2 medicines. I only began it as a last ditch try in Jan 2023 since she was diagnosed with hemingiosarcoma around her heart and vet gave her no more than 2-4 weeks. She was having seizure, stroke -like episodes with labored breathing before diagnosis.
Your Miss Tillie is so very tiny. I do not know what to suggest for dosing. 8 pounds is so different than 40 for figuring dosing. But you have given her 3 more years using your knowledge and instincts, so keep it up, and prayers for you and Tillie. Hope that helps. Daisy May 5, 2023 is still a happy girl, going on walks, eating well, wagging her tail. I hope the same for Miss Tillie
Hi Trying, thanks for your kind words. I'm so happy Daisy May is doing well. My heart goes out to you both. It's so sad that the vets can't prescribe these drugs for cancer. My oncology vet knows that Miss Tillie is getting them and says to keep going but since it's off label, she doesn't have much experience with it for cancer.
I feel very certain the neurological symptoms were due to the Ivermectin. She started the shaking about 3 days after I increased her dose to .3mls daily and stopped by the morning after I stopped it. She was on no other meds at the time and since it has completely stopped it’s not the disease progression. Also I did a little research afterwards and neurological side effects are well documented in the literature, mainly in Africa because they have had widespread use of Ivermectin decades after people in the US started using it.
I give the injectable Ivermectin orally to her because it much easier to control the dose than the paste. And I use the Safe-guard Fenben suspension. Its interesting that after posting, I did find a combination ivermectin/fenben product - Ivermectin 2% + Fenbendazole 20%, Oral Suspension so apparently we are not doing something that hasn’t been done before. It’s prudent to do the on/off schedule. I actually hadn’t checked the half life out on the drugs but I think I will give the Ivermectin every 3 days to restart and the Fenben daily to see if we get a response. Thanks so much for that!
I’m not sure which website I used to calculate the dose but I know it was a site online and it was for veterinary use but I will be sure to check out Joe Tippins site. I’m very thankful that I found this webpage and have the experiences of other people in the same situation to learn from.
You really should follow Joe Tippens protocol and others. I am just guessing basically but somehow she is still here. But i know you want to know. So...Daisy is 40 lb pointer. 4 days a week we put 1 teaspoonful of Safeguard liquid goat dewormer 10% suspension over her food. This = 6 ml of the oral suspension. I think the suggestion is now to do it 7 days a week but we've just stuck with 4 days a week. Then I put a tiny dab of ivermectin horse paste on her food twice a week. The tubes are calibrated to a 250 pound increments usually. So I try to do 1/5 of that which is basically a small dot smaller than a pea. I use the same dose recommended for most mammals. 91 mcg per pound. The papers I've read on both of these substances suggest they work in 2 different ways against cancer. Since I felt like we had nothing to lose, I went ahead and did both. It could be that Fenben by itself is just as good. As far as I can tell she has had 0 negative side effects. I began them a week apart so that if she did have a problem I could perhaps tell which medicine gave her the problem. But she had no problems.I will warn you, even armed with calculators and the instructions right in front of me, it gets very confusing figuring the difference of milligrams mg and micrograms mcg and grams g and milliliters ml and microliters mcl..mind blowing. My husband decided on the teaspoonful instead of syringe. She eats it readily on her food. I was concerned that if I made the dose even larger it might get to the point where she would begin to reject it. At this level she's still alive, she eats her food easily, and that's about the best we can do. Please keep me posted on your little furry creature. I'm so sorry you're having to come to this site. Again I pretty well made up the dosage Daisy is on and please understand that!
My 5-year-old dog was diagnosed with lymphoma last week, with every lymph node extremely swollen. Fortunately, I had been reading about fenben curing cancer in humans elsewhere on the web and researched the dosage info for dogs. Our veterinarian said the prognosis was 3-6 months without chemo (which he does not recommend). I talked to him about fenben and he said he doesn't think it will work, but to try it if I want. I gave our dog doses on Friday, Saturday, and Sunday. Today is Monday and the lymph nodes on his neck have reduced to about 1/3 of the original size. After each dose, there was significant reduction after only about two hours. I'm going to give him four days off and start another round. Hoping this continues!
Thanks for creating this substack. I'm loving the articles and comments!
Puppy's lymph nodes are way down and he is very active and happy. Will update again in a couple weeks. Keeping him on a high protein dog food.
How is your dog doing?
👍
One side is now down to 1/4 of the original size on Friday before fenben. I also started a higher protein diet, phasing out the kibble, but that has to be done slowly so they can adapt to the food change.
I wonder how your vet will use the knowledge you’ve given them?
Our vet called a bit ago. He said he was amazed to hear what I said about the lymph nodes subsiding. He said "maybe we're onto something." I'm scheduled to stop by there tomorrow and will give him the address to this substack to check it out and fenbendazole.org.
My husband just got home from a trip and agreed that the neck nodes are way smaller. He also checked the nodes on his legs and said they are way smaller, too. He wants to bring our pup over for the vet to check tomorrow. My husband has known the vet for approx. 20 years. Vet has been in practice for approx. 50 years.
Some of the images we’re receiving involving visible tumor reduction in dogs is along the timeline of weeks not days. I was wondering if it is at all possible that your dogs “tumors” are actually pockets of parasite infestations? Don’t know if that’s even a possibility, just trying to account for the amazingly rapid response to fenbendazole.
I don't know. He is also taking doxycycline because a tick-borne disease was detected. Not sure if that would aid in the reduction.
The vet hasn't heard about it working, yet, but I think he will be shocked and in disbelief when he hears the result. He had called an oncologist friend who told him it wouldn't work and that settled it for him. Hopefully, he starts prescribing it to other patients in need. Dog continues to improve today: one neck lymph node is almost completely back to normal state. He seems fine except for sleeping more than usual, but I think that's just part of the recovery process.
How has it been going for you? My baby was diagnosed at the end of May. I had put her on the fenben for a couple weeks and took her off. She weighs 10 pounds and I started worrying I was giving her too much. She's on prednisone right now, but considering adding fenben back in the mix. How has your baby been doing?
Is Fenbendazole by prescription only?
No. You can get it at the pet store or amazon
She continues to be just fine. If I did not know she had a tumor around her heart, I actually would not know. I continue to treat her and I really don't have any way of knowing what is working, but something seems to be working. She has exceeded the predictions by several months now. First collapse Nov 22. "Two weeks to live" soon after Christmas. I am also not sure i am dosing her ideally. I am using the goat panacur liquid, 6 ml. I squirt it on her food. She is ~ 45 pounds and a 50 lb dose of ivermectin horse paste ( tiny bit). As long as she continues to have a good appetite, wag her tail, explore outside, act happy, i will continue. I am sorry about your sweet Sheltie. Don't have regrets, i know you did everything and your pup knew too.
I have a question. Are you giving therapeutic doses of BOTH Ivermectin and Fenben? I have only given 1 of them at a time for canine lymphoma and we are going on 3 yrs but she had a neurological reaction to the Ivermectin when I increased the dose. I stopped everything for 3 days but the lymphoma is coming back. I started the Fenben again today but it sounds like you are giving both which is what I've been considering. Thanks for your thoughts.
I'm sure it is written somewhere but I can't find it and I'm new to this site. For the canine cancer, is the dose the same no matter what size the dog is? I have a 40 lb dog. And do you give that dose every day from then on? Or do you give it for a set amount of time? My dog has Hemangisaroma on her heart. Just since last night I'm afraid she is in quite a bit of pain. I'm actually considering on euthanizing her today. But if this might help I'm willing to try. I just want to get it right. There's nothing to lose. Thank you
One idea is to go with 222 mg twice per day. The half-life of fenbendazole is around 8 hours, so splitting it up into two doses spaced 8 hrs apart will should help optimize the impact.
Just an update. Took my sweet doggy Daisy with the aggressive tumor on her heart to be euthanized yesterday because she was in terrific pain. We were all the way there in the room and I had signed the paper. The vet could see her acute pain and we had been warned that this would happen at the end. However he felt like something didn't look right. He found an enormous abscess inside her mouth! Lanced it and immediately Daisy normalized. We tore up the paper and I thanked them profusely and she is back home with me today. I will be getting FenBen. However I have a big question. When we discovered her aggressive cancer and we were told just to keep her comfortable, give her a few palliative care pills a day, and take her home, I started her on daily Ivermectin which also has been shown to kill cancer cells. I reread several of those iver cancer papers again recently just to make sure. It was the category of "might help can't hurt". I am a little concerned of adding Fenben to the mix. I found one paper comparing the two and it appears they work with different actions against the cancer cells. But I can't find where anyone has tried a combination of the two either in humans or animals. Has anyone else? But I also don't want to make some sort of toxic combination especially since I will be doing both of them daily. Has anyone else tried this for have any experience? By the way on the ultrasound yesterday of her heart the vet said it actually looked very good compared with two weeks ago. So that encouraged me about the Ivermectin possibly helping already. But who knows? Thank you
Don’t know about any potential interactions between IVM and FBZ.
Just an update on sweet 14 yo Daisy. It has now been 6 weeks since she was given roughly 2 weeks to live. I am giving her Fen Ben 4 days a week, and Ivermectin about every other day. I'm just guessing at all of the doses. Who knows where the truth is but I can tell you she acts perfectly fine and perfectly comfortable. She does not have the stamina she used to have but other than that she is bright-eyed with a great appetite, wagging tail and no pain.
I have been wondering about giving my girl both Ivermectin and Fenben. We've had tremendous success keeping the lymphoma down with the Ivermectin but we just can't completely irradicate it and each time we stop the Ivermectin it seems to come back. How is your sweet daisy doing on both? Any side effects? Does it seem more successful than either drug alone?
As long as she is eating and not in pain GO WITH IT!
Thank you
Please give us an update on Daisy. I wish I had known about fenbendazole and ivermectin when my beloved Sheltie developed cancer four years ago. 🐾
Daisy is doing well still on April 17, 2023. Eats, plays, takes walks, wags tail. I still give her fenben 4 days a week and ivermectin 2x a week. Who knows? But we were told to take her home to die with a 2 week prediction back in late Decearly Jan
So glad to hear the good news. 🤗
Can you tell me the dosages you are giving Daisy? And how you determined the dosages? Thank you.
I just replied but not sure it went to you. Check comment above
The case studies here indicate that fenben alone is all that’s needed. Other substances aka Tippen protocol, are not necessary. Prednisone mediates inflammation so it is most likely irrelevant to the anticancer effects of fenben.

That has not been my experience. Fenben was minimally effective. We have found for our girl's lymphoma, the Ivermectin has been very effective but she began developing neurological side effects so we are exploring a combo therapy
Ok. Apparently there are no known drug interactions between fenbendazole and ivermectin according to drugs.com
