Tips to Prevent Food Allergy Flare-Ups in Your Pet Leave a Comment / MyCollection / By Dr.Abdul Khaliq Baig What Happens Food allergies in pets work just like they do in humans. Your cat or dog’s immune system mistakes an ingredient in their food as something harmful. Their body shifts into defense mode, which causes allergy symptoms to start. Your pet might have red skin or itchy ears. They could start to have an upset stomach or diarrhea. Cats are also likely to get small, fluid-filled bumps, often around their head and neck.
