Elbow dysplasia is a condition caused by the abnormal growth of cells, tissue, or bone. This happens due to developmental abnormalities leading to malformation and degeneration of the elbow joint. It is the most common cause of elbow pain and lameness. This is more common in large and giant-breed dogs. Labrador retrievers, Rottweilers, Golden retrievers, German shepherd dogs, Bernese mountain dogs, chow chows, bearded collies, and Newfoundland breeds. Symptoms are typically in 4 to 18 months though not all dogs will show signs when young. The dogs will tend to hold the affected limb away from the body.
