@gotitchypet: We cannot prevent a food allergy. Any food ingredient can cause an allergy. You can be feeding your pet the best, most expensive food for years and your pet can suddenly become allergic to its food. Elimination diet trials are still the gold standard way to assess food allergy in pets. It involves switching the pet to a prescription novel protein or hydrolyzed food that can only be prescribed by a veterinarian. Some dermatologists like to do a home cooked novel protein diet for diet trials, and this is perfectly acceptable if the food is nutritionally balanced. During the diet trial the pet needs to eat the food strictly for 8-12 weeks. Despite what I stated above, there are still misconceptions in the vet community and amongst pet owners of what constitutes a good diet trial. What questions do you have about diet trials? #dogfoodallergy #canineadversefoodreaction #foodtrialsinpets #petdermatology #bestdogfood #petownersofinstagram #vetdermatology #dermatologiaveterinaria #vetmedicine
