BLUE Basics Grain-Free Duck & Potato Recipe is a limited-ingredient diet formulated to minimize food sensitivities some dogs experience, while maximizing the nutritional value they receive. Contains deboned duck as a single animal protein source. Kibble is made of easily-digestible carbohydrates like peas and potatoes. Pea fiber & pumpkin are inlcuded to support gentle digestion. No chicken (or poultry) by-product meals. No corn, wheat, soy, dairy or eggs. 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.
