NutriSource Senior Dog Formula – A specially formulated dry food to meet the needs of senior dogs. It is moderate in calories and fat to help prevent weight gain in less active dogs, and it includes additional glucosamine and chondroitin to support aging joints. Real chicken (and/or other proteins) supply easily digestible protein to maintain muscle mass, and whole grains and fiber support digestive regularity. NutriSource’s Good 4 Life supplements are added to enhance gut health and immune function in older dogs. With its balanced nutrition and targeted senior support, this formula helps keep your dog feeling youthful – promoting healthy weight, mobile joints, and a strong immune system as they age gracefully.
