"Best way to prevent, or at least prolong the time before your old dog becomes arthritic is to keep them lean and strong. This is also important for longevity and overall health, so it should be your main goal if you want to keep your dog alive and well for as long as possible. I can't stress the importance of keeping your dog fit and strong if it has osteoarthritis. If your dog is overweight joints have to bear more weight, and if it's muscles aren't strong joints bear even more weight then they should, which leads to increased friction and damage of the joints. If your dog is in perfect physical condition (body condition score 4-5 on 9 point scale) joints bear minimum amount of weight they have to, and if it's muscles, tendons and ligaments are strong they reduce weight bearing of the joints even more. This is important for overall health, as well as in cases of osteoarthritis and other orthopedic conditions. So keep your dog fit and strong. ."
