you have to do a 12 week trial to do an true elimination diet. it needs to be a novel protein and carb so switching around to a bunch of foods will only confuse the situation -- if you want to do a true elimination diet you can do a protein she has never eaten before such as buffalo, venison, pinto beans, cod, lamb, etc with sweet potato i recommend as white potato is inflammatory and a multi baby vitamin and do this for 12 weeks straight with nothing else entering the body . Odds are it will help a little but if still itching most likely biggest issue is environment which is in most case - however an environmental allergy dog still needs to eat a minimal ingredient diet keeping down the amount of items entering into the dogs system as to not over toxicate the system thus allowing it to get over whelmed and cause itching from any little thing. Allergents are proteins which are flea saliva, meats, and pollens |
