Osteoarthritis (OA), also known as degenerative joint disease, is the most common form of arthritis in dogs. OA is the loss of cartilage that protects the ends of bones in most joints. If a dog is experiencing OA, you will see an overall decrease in activity and reluctance to exercise.

Several treatment options are available, including nonsteroidal anti-inflammatory drugs, pain medications, joint supplements, local injections, weight control, activity modification and surgery.
