Osteoarthritis (OA, also known as degenerative joint disease) is characterized by the degeneration of articular cartilage that lines the ends of bones inside a horse’s joints. OA is the No. 1 cause of poor performance in horses and accounts for nearly 60% of all equine lameness cases. Horses of all ages can develop OA, but what can you do to slow its progression or treat this disease? Two experts weigh in to answer your common questions about equine OA.

This episode is brought to you by American Regent Animal Health.
