While my dogs like all of the flavors that we have tried of this dog food, for some reason their itching increased when I tried the lamb and rice. I have some very itchy dogs and am giving them a limited ingredient dog food to try to help. The duck and sweet potato cut down on the itching significantly, but when we tried lamb and rice they started itching more once again. I like Natural Balance for the quality ingredients.
