Some dogs can’t handle grains, a lot more than vets realize. The wolves they desended from would have had very little grain in their diets, and while dogs can handle starches better than wolves can, that doesn’t mean they should be on a diet that is primarily starch. As long as the chicken and rice is working for your dog, then it is fine, for the short term. It would cause diarrhea and much more severe problems in mine. I would have to use turkey and sweet potato or something like that. If my dogs ever have upset stomach issues, which is extremely rare, I just fast them for a day and it clears right up.
