Can Dogs Be Allergic to Food? Yes, but it often takes some detective work to find out what substance is causing the allergic reaction. Dogs with a food allergy will commonly have itchy skin, chronic ear infections or sometimes gastrointestinal problems like diarrhea and vomiting, and an elimination diet will most probably be used to determine what food he is allergic to. If your dog is specifically allergic to chicken, for example, you should avoid feeding him any products containing chicken protein or fat. Please note that food allergies may show up in dogs at any age.
