Like humans, as dogs get older they lose their capacity to naturally 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 older dogs, large breed dogs and highly active or performance 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.
