Eles7 ~~ when you are dealing with allergies (or intolerances) you have to look at ALL ingredients in the foods you feed. Potato is a relatively common food that causes intolerances. I have a friend who’s dog develops issues when she eats green beans. I know another dog that has an issue with garlic. My own dog can’t have beef bone (the meat is okay just can’t have the bone). Eggs, dairy, peas and many other foods can also be the problem. Going grain free and switching to a novel protein is a good start but many times it isn’t enough. Is there anything in common among all the foods you have tried? If so, I’d try a food that doesn’t include that — Nature’s Variety Instinct and Brothers Complete, as examples, use tapioca instead of potato (both have peas and eggs though). Nature’s Logic uses millet and other foods use garbonzo beans (aka chick peas).
