Our formula is thoughtfully made with USDA "fit for human consumption" whole foods including deboned whitefish, ground pearl barley, sweet potatoes and ground flaxseed. Our Limited Ingredient formula supports skin and coat health and digestive health with a single animal protein source from fish specifically targeted for dogs who need a limited ingredient diet. Super5Mix recipes represents a synergistic combination of natural ingredients created with your dog's whole-health in mind. Instead of several different proteins, we use fish as the primary protein source. This omega-rich ingredient is complemented by an easily digestible carbohydrate blend that includes sweet potatoes. Plus, we ensure excellent nutrient digestibility through our Digestool confirmation studies - less nutrients in the stool, means more nutrients stay in the body.
