Like with humans, as dogs get older they lose their natural ability to repair cartilage at the joints. This can lead to arthritis and hip dysplasia - diseases that erode and inflame joint cartilage. To improve the quality of life for older dogs, ACANA diets are supplemented with glucosamine, chondroitin and omega-3 – all of which are natural nutrients that promote cartilage and joint health, and improve overall mobility, and wellness and quality of life.
