Elimination/Challenge, also known as Food Allergy Diets, are diets in which all protein sources that your pet has been exposed to (ex: chicken, pork, beef, corn, wheat, milk, egg, soy, etc.) is eliminated from his diet for a period of 10 to 13 weeks. When your pet's physical allergy symptoms subside (sores heal, stop scratching or chewing, etc.), then one previous protein, ex: chicken, is reintroduced into your pet's diet. Recurrence of old allergies are watched for closely. If your pet begins to demonstrate old symptoms, then that protein is once again eliminated from diet and when the allergy symptoms subside, another protein is reintroduced into his diet, thus challenging your pet's diet. In this manner, your veterinarian can determine exactly which proteins your pet is allergic. Hopefully, your pet can return to a normal diet with only a few proteins eliminated.
Your veterinarian may put your pet on a variety of different diets. They will choose a diet consisting of proteins your pet has never eaten.
