The breeder that I got Fauna from has been using Canidae food for years and swears by it. She also put us on to a supplement by Nu Vet. She has been using it for quite a while and believes it helps her dogs overall health and also keeps many of the skin and tummy issues at bay. For more info www.nuvet.com. I have spoken to the folks there and they are most helpful in answering questions and making suggestions.
