How common is osgood-schlatter disease in dogs?

Osgood-Schlatter disease is not a condition that affects dogs. It is a condition that affects humans, specifically adolescents, causing pain and swelling in the knee.

In dogs, the equivalent condition is called osteochondritis dissecans (OCD), which can also affect the knee joint, but it is a different condition with different causes and treatments.

It's important to use accurate terminology to avoid confusion and ensure that you're receiving the correct information. If you're concerned about your dog's health, it's always best to consult with a veterinarian.
