Summary
Panacur for cancer in dogs?? It’s a dewormer! #dogcancerconfusion! Time to ask Dr. Nancy Reese to do some research.
In this week’s episode of Dog Cancer Answers, Dr. Nancy Reese answers a caller’s question about using a dewormer, fenbendazole, brand-name Panacur, for dogs in cancer.
Does Panacur Help Dogs with Cancer?
Sandy called our Listener Line (you can too! Call +1 808-868-3200) and left a recorded question for our veterinarians. She’s been reading about Panacur, also called fenbendazole. Does the dewormer help dogs with cancer? Or does it, as some folks say, make cancer worse?
Dr. Nancy Reese joins host James Jacobson to answer this most-interesting question.
Research on Fenbendazole for Cancer
Why Dr. Nancy? Because not only is she a practicing veterinarian with over 30 years of experience … she’s also got a Ph.D. in Epidemiology. That means she’s an expert on deciphering and assessing scientific papers.
And the results of her research on fenbendazole were fascinating.
As with so many things dog cancer, the answer is not clear-cut. It’s not “yes, absolutely, use Panacur.” It’s also not “no, definitely do not use Panacur.”
It is, as always, more complicated.

My 17 year old Pomeranian just had his spleen removed with a large tumor on it. The pathology came back positive for cancer but because the tumor was so big they couldn’t distinguish what type of cancer it is. My vet decided to start chemo but this treatment has affected my dogs appetite. I’m wondering if panacure could be an alternate treatment for Onyx.
I also need to know what to feed him and how I can make homemade dog food that would be tasty and appetizing
Hi Lourdes, I’m so sorry about your dog. I’m afraid that Panacur is not a substitute for any chemo drugs at this point. The doses that would be needed (if we ever use it in oncology) would be SO HIGH that they would likely cause the same side effects and long-term problems current drugs do. For a homemade diet, of course, I recommend Dr. Dresslers: https://dogcancerdiet.com
Hi Molly, I appreciate you & the information that you have shared. My 11yr old golden mix has lumps all over his body. I have not had them aspirated due to a bad experience with one of my other dogs. Today I was told about Panacur for cancer use. Do you think I should try it to help shrink or further growth of tumors?
My havanese h Has just been diagnosed with cancer I’m wondering if we can help her survive
My dog was diagnosed with a mass in her liver and abdomen . Do you have recommendations of what vitamins to give with fenbendazole?. Is there any one I can talk to on the phone about this?
Hi Donna – the team here at Dog Cancer Blog are not veterinarians, so we can’t offer phone consultations. I recommend reaching out to your regular vet or oncologist, or a holistic veterinarian or integrative oncologist. Some of them are doing phone consults now so you don’t necessarily need to find someone in your area. Best of luck to you and your pup!
All I can say is that this is the most comprehensive writing I have found regarding dog cancers, treatments and feeding. If I had this book 10 years ago our dear Nila, a Pembroke Welsh Corgi would still be with us. We found this book and this site just a. It too late. It is now my aim to aim people to this page/site and the book so others do not have to go through the heart wrenching times we had to. My cry now is “kibble kills”. This book is essential reading for present fogs owners and certainly for those contemplating getting a dog.
Paul, thank you so much for your comment.
