Your dog is not improving on a rX diet because it is grain free. It is because it is free of an ingredient that bothers your dogs GI tract. As Crazy4cats stated I am a licensed vet tech and I 100% support rX diets as I’ve seen the wonders they do. I am talking about OTC grain free diets that are designed with the sole purpose of marketing to naive pet owners who think they are feeding a superior product because grains are absent from the diet. Not rX diets that are formulated through extensive testing and research.
