I feed my Setter Nutri System dry food based on the recommendation of the breeder who feeds it to all her dogs and puppies. She also told me that Greenies are the worst thing you can give your dogs so I no longer give our dogs Greenies. There is an epidemic in this country of dogs being allergic to commercial dog foods, that is one of the reasons we are seeing the various meats not contained in dog foods that were never in it before such as rabbit, bison etc. My wife's Scottie is allergic to almost every kind of food. He would break out in rashes all over his body. He has been on Hydrolyzed Protein dry and canned food made by Royal Canin veterinary diet which is very expensive but our Scottie doesn't suffer any more and he is a new dog with lots of energy. There was a time when people just bought whatever was in the store or the feed mill, we can't afford to do that any more, if we take on the responsibility of dog ownership, we take on the expense of properly caring for them.
