Misconception About Food Allergies
A common misconception is that feeding wheat causes food allergies. The facts are:
The pet must have a hypersensitivity to the food or ingredient. An allergy is an adverse reaction of an individual animal to proteins in the diet.
Food allergies are rare in animals and account for a very low percentage of allergic reactions in dogs.
If your pet has a food allergy, he is most likely allergic to one ingredient or a combination of ingredients in his diet. In a U.S. study of food-allergic dogs, the two common pet-food ingredients that most often caused an allergic reaction were beef and soy.3
Gluten (a protein found in wheat) is responsible for wheat-sensitive enteropathy, occasionally found in Irish Setters from the United Kingdom. Gluten enteropathy of Irish Setters is a malabsorption syndrome, which responds to the removal of wheat (gluten) from the diet. This condition is very rare, and the reason some dogs develop it is not yet clear.
