Food allergies only account
for 10 percent of
allergy problems in
dogs.
Dogs often can not tolerate soy products, wheat, corn, beef, pork, chicken, milk, whey, eggs, fish, chemical preservatives, or artificial sugars in their food.
Determining the food allergen can be time consuming. First, eliminate all the possible allergens from the diet, by using a home made diet consisting of a protein and a starch the dog has not eaten before.
