OCD is a cartilage problem that affects young large and giant breed dogs. It is due to several factors including genetics, trauma, rapid growth and nutrition.
The owner of any large breed puppy should be warned about the risks of OCD and advised on how to minimise development of the condition. Puppies should not be exercised on hard surfaces or allowed to jump or run downstairs until they are skeletally mature.
They should be fed on large breed puppy food, which has the correct calcium/phosphorous ratio to promote correct development of cartilage and bone.
