Osteochondrodysplasia is an inherited Musculoskeletal disease affecting dogs. Affected dogs typically present at about 3 weeks of age with stunted growth. Puppies often walk differently than unaffected littermates and stand with their feet turned out and hind legs splayed. Their legs are short and bent with enlarged joints and clubbed feet. They also have flatted rib cages and under bites, which can affect their ability to nurse and breathe. While affected dogs can survive for many years with supportive care, they will develop arthritis and likely will have breathing difficulty due to their deformed ribcages.
