I think I misread your issue with your dog…lol. You would basically need a low protein dog food.Most pet stores will have the knowledge of this or should anyways. Are you in USA or Canada? Brands are different. Chicken Soup brand of dog food is good. Just make sure first so many ingredients are meat and not fillers. Feeding better food will make better health for your doggy.
