Allergy or intolerance to certain foods, such as seafood, milk or peanuts, is common among people. Dogs also can have food allergy or food tolerance issues, although their manifestation can be different from what people experience.
Food allergies in dogs can develop at any time — even after years of eating a food without problems. The culprit is usually a common protein source, such as beef or dairy, but dogs can become allergic to any such ingredient. That means the best dog food for any given dog can vary depending on their specific sensitivities or intolerance.
Adverse food reactions account for approximately 10% to 15% of all allergic skin dermatitis
in dogs and cats.¹
