Old English Sheepdog OCD: When Growing Fast Outpaces Cartilage Development

It's a cartilage development disorder where cartilage growing faster than its blood supply becomes fragile and can crack or partially detach within a joint, causing pain and lameness in growing puppies.

Hip dysplasia is a problem with how the joint itself is shaped and fits together. OCD is a cartilage nutrition and growth problem that can affect several different joints, most often the shoulder in large breeds, and isn't about joint conformation at all.

It typically shows up between four and eight months old, during the period of most rapid growth for a large-breed puppy like this one, though it can occasionally be diagnosed slightly outside that window.

A limp that comes and goes with activity level, often worse after exercise and easing somewhat with rest, is typical, distinct from the more constant stiffness patterns sometimes seen with joint conformation issues.

Not always. Milder cases caught early are sometimes managed successfully with strict rest and activity restriction alone, while more advanced cases with a detached cartilage fragment generally do better with arthroscopic surgical removal.

Not entirely, since rapid growth itself is a contributing factor, but avoiding excessive high-impact exercise and not over-supplementing calcium or overfeeding a growing large-breed puppy can reduce the risk and severity.

If treated promptly, many dogs recover well without lasting issues. Delayed treatment can allow secondary arthritis to develop as the joint compensates for the unstable cartilage, which is why early recognition matters.
