Whitney, Evie, & Armaiti May with David from V-Dog
Question: I was wondering if you had more information on how the transition affects the dogs, and how long the transition takes. Obviously every dog is different but I'm curious to know more. We want to foster dogs, and some folks are concerned that the transition to a vegan diet for however long we have him and then a transition back to a meat-based diet will be detrimental to the dog. That his digestive system will be overly taxed by this flip/flop.
Answer from Dr. Armaiti May, vegan dog specialist & vet.
I recommend gradually increasing the proportion of vegan food, while still feeding the former diet that the dog is accustomed to, over a period of 1-2 weeks, until the vegan food comprises most or all of the dog's diet. This gradual approach should minimize the occurrence of gastrointestinal upset (vomiting and/or diarrhea).
If the dog is going to be switched back to the other diet shortly after being fostered, however, it might be beneficial to include some small amount of it along with the vegan food so that he/she doesn't suffer from gastrointestinal upset once put back on the diet after being off it for a long period of time. Sometimes adding pumpkin or squash in small amounts can help keep the stools a normal consistency if there is a dietary-induced change in stool quality. If the dog eats something that causes vomiting, a period of fasting (with veterinary guidance) and/or bland diet of tofu and rice may be indicated for a few days until the dog's system normalizes again.
