NATURAL CHOICE® Small Breed Senior Dry Dog Food features our unique SENIOR SUPPORT SYSTEM® Formula that was created specifically for older, small breed dogs. Many smaller dogs live up to 20 years, so they’ll benefit from our premium blend of natural antioxidants, omega-3 fatty acids and protein to support their immune systems and meet their energy needs. Made for smaller mouths that are prone to overcrowding, our kibble can help naturally reduce plaque and tartar buildup. Your senior dog will enjoy the taste of real chicken, whole brown rice and oatmeal. And you’ll love the results — guaranteed.
