BLUE Wilderness is a high-protein, low-carb, grain-free diet that was inspired by wolves. It is made with deboned salmon, menhaden fish meal and chicken meal that supply the protein your dog needs. Sweet potatoes and potatoes provide healthy complex carbohydrates. Blueberries, cranberries and carrots support antioxidant-enrichment. Kibble is made of LifeSource Bits that contain a precise blend of vitamins, minerals and antioxidants selected by holistic veterinarians and animal nutritionists. LifeSource Bits are “cold-formed” separately from the rest of the kibble to help preserve the potency of the ingredients.
