When your dog's stomach isn't happy, nobody is happy. Now you can help reduce stomach upset and support healthier stool with Gastrointestinal Biome Chicken Flavor dog food from Hills' Prescription Diet. This exclusive recipe was formulated by Hill's team of nutritionists and veterinarians using a different approach to digestive care. The kibble works with the bacteria in your dog's stomach to break down his breakfast, dinner and everything in-between. This blend of active fibers helps food move through the body naturally—and regularly—by encouraging the release of postbiotics.
