Mainly affects, shoulder, elbow (also known as elbow dysplasia), stifle, and hock joints affecting both sides. OCD causes secondary osteoarthritis.  Genetics and nutrition (lesser extent) are thought to be the cause. Symptoms, lameness/stiffness mainly after exercise and rest, muscle atrophy, and uneven weight bearing. Develops 5 to 8 months old.
