What is the Best Food for Dogs with Allergies?
In order to identify the best food for dogs with food allergies, you must first understand what food allergies are and what causes them.
Many different terms are used to describe abnormal reactions to food. The terms “allergy” and “hypersensitivity” describe an immunologic reaction to food allergens and requires previous exposure to the allergen to bring about symptoms. By contrast, a dog food "intolerance" does not involve the immune system and can occur with the first exposure to a certain dog food. Both reactions produce similar symptoms and may be difficult to tell apart without veterinary guidance.
In fact, according to Dr. Adam Patterson, clinical assistant professor and Chief of Dermatology at the Texas A&M College of Veterinary Medicine & Biomedical Sciences Small Animal Clinic, "Food allergies in dogs present themselves quite differently than food allergies in humans. For instance, a person who is allergic to shellfish may experience throat swelling and possibly a critical or fatal reaction, but in dogs, the allergy is expressed through the skin and seen most often as itch."
