OCD, or osteochondritis dissecans is a disease that affects the soft cartilage tissue between the joints that provides cushioning and allows the joints to work smoothly. When this cartilage is damaged or eroded it can lead to arthritis and joint damage.

When a dog has OCD, the cartilage either separates from the bone or develops cracks and pieces may break off which continue to grow causing extreme pain for the dog. This can be the result of damage to the cartilage or due to abnormal growth and is often seen in large breed dogs such as Golden Retrievers, Labradors and Rottweilers and in most cases begins when the dog is a puppy. However, OCD can affect any breed of dog.

The condition can be caused by a number of factors such as genetics, injuries, unusually rapid growth or a restricted blood flow to the cartilage and displays with lameness in the affected leg with pain and limping which is particularly noticeable after exercising. Most cases of OCD occur in the shoulder joint, but the disease is found in the elbow joints and sometimes in the hock.

As with other joint diseases, treatment can be either in the form of surgery to repair the joint or anti-inflammatory medications and painkillers. With proper care, most animals with the disorder can be successfully treated and their pain either eliminated or reduced to allow for a long and healthy life for your pet.
