You know your dog’s body changes over time. It’s part of a natural process. And their nutritional needs change right along with it. With less fat for weight control and more protein to maintain lean muscle mass, Advanced Pet Diets® Select Choice™ Senior Adult Dog Food was created for less active dogs, 6 years old and up. We’ve enriched it with the vitamins and minerals that older dogs need most. And to help keep your dog’s hips and joints healthy and pain-free, we’ve also added natural bovine cartilage, with glucosamine and chondroitin sulfate in a highly accessible form.The antioxidant-rich formula in all our foods is more important than ever for keeping the immune system strong and preventing disease, while the omega 6 and 3 oils help ensure healthy skin and a shiny coat throughout your dog’s life. The probiotics or “good bacteria” that we’ve added promotes good digestion and full nutrient absorption, not to mention easier clean-up!
