food allergies in dogs and cats

Get help honing in on your pet’s allergy-based itchiness or diarrhea
Food allergies can be tricky to diagnose, because they often share symptoms with many other pet health problems. One thing to bear in mind is that pet allergies, unlike human allergies, don’t typically show up as red eyes or runny noses. Many food allergies will first show up on skin, or as no-fun-for-anyone pet vomit or diarrhea. Your veterinary team is here to help you identify what’s causing the problem, and to offer diet and feeding advice that may help your pet.
Dogs are 6 times more likely — and cats are 15 times more likely — to develop uncomfortable skin conditions if they have food allergies. See more about skin symptoms
