My 3 year old dog has just had allergy tests done. It turns out he’s highly allergic to all common meats present in most dog foods, fish, soy and most carbs. The only thing he wasn’t allergic to was eggs, cow’s milk and he can tolerate wheat. I have been suggested an insect protein diet or perhaps to try kangaroo. Anything I find seems to have potato or rice in, which he can’t have. Does anyone have any suggestions?
