would the mix of both of these cause diarrhea ? i know there probably isn't a point to mix a non-grain kibble with grain but i need to change my puppy's food
fromm surf & turf to fromm whitefish & potato -_-' he seems to enjoy the surf & turf much more but i think he has allergies to chicken and there's chicken fat & broth .. do some dogs tend to like non-grain then grain food ?
