OCD is a degeneration of bone underlying the cartilage layer
of joints. It can affect the shoulder, ankle or elbow joint and
almost always shows up during the growth phase — between six to
nine months of age — of larger breeds. It may start as an
intermittent limp in one leg. Many young dogs with OCD run and
play as though nothing is wrong but when they slow down they
realize the limb hurts and the limp returns. Contributing factors
to OCD include both environmental and genetic factors. Dogs whose
parents had OCD are much more likely to also suffer from this
disease and physical trauma to the joints may also cause the
already weakened cartilage to chip and crack.
