Natural Balance Specialized Nutrition Small Breed Digestive Health – Chicken (12 lb) – A larger bag of the Small Breed Digestive Support formula for dogs. It provides the same carefully calibrated nutrition as the 3.5 lb version – real chicken and lamb for protein, oatmeal and pumpkin for fiber, plus active probiotics – to help little dogs with sensitive stomachs digest their food comfortably and absorb nutrients efficiently. With extra kibble on hand, you can consistently feed your small canine companion the diet that keeps their tummy happy and immune system robust, meal after meal.
