It's not just older dogs that suffer from joint problems. Young dogs grow very quickly and are extremely active, all of which can take its toll on dog's joints, ligaments and tendons. Fast growth, over exercise, injuries and strains can all cause joint problems which can continue for the rest of their lives if not looked after. This formula has been specially formulated with increased levels of green lipped mussel, manganese, vitamin E and added zinc to support your young and active dog's joints. NOT CURRENTLY AVAILABLE - DUE END OF JULY.
