Rabbit, white potatoes and pumpkin. 95% of dogs are allergic to these three foods. Pumpkin is the most surprising because it is a modulator. It will fix constipation  and diarrhea . Use it for that and then get your dog off of it. It is a very high allergen squash! White potatoes are a cheap filler. A cheap starch that turns to sugar. Dogs and cats dont need sugar. Rabbit is a worse allergen than  Chicken which rates high as well.
