We have fed a number of dog foods through the years, but since we have been feeding Prism (since 2007), we no longer have trouble with hot spots in our bulldogs, have no "skinny" boxers :) and my vet always tells me what nice glossy coats my dogs and puppies have. Most breeders will say not 1 dog food  will work for every dog, that might be true but all my dogs love the taste of prism dog food and do well on it. ~ Brenda

I was feeding Diamond dog food and had some trouble with dull coats and not digesting it very well. Since we switched to Prism Pooch has a glossy coat and she digests it very well. She also loves the food :)
