What kind of fistulas? Are they related to allergies? Blocked anal glands?
My dog with allergies does well on Nutrisca (fish), assuming your dog can have fish, I know it contains no potato or grains. Wysong has a vegetarian blend.
I may start getting my Nutrisca from chewy.com because the prices are better.
I like Wysong and consider it to be a quality food and still feed it to my senior dog. However I noticed my dogs seemed to be drinking more water, so I worried that maybe it’s high in sodium? If that’s a concern I think someone at their company could answer your questions.
PS: Consider consulting a homeopathic vet, they may have some treatment ideas different from the traditional vets http://www.vitalanimal.com Some of them do phone consults, if there isn’t one located near you.
