Causes
The cause is not fully understood, but it is linked to rapid growth. It is more common in males of large breeds, especially the German Shepherd.
Diagnosis
Physical examination (pain on bone palpation) plus X-rays showing characteristic changes.
Treatment
It is self-limiting: it resolves on its own once growth is complete. Only the pain is treated during flare-ups, with painkillers as prescribed by the vet. Rest during episodes.
Prevention
Not preventable, but avoiding excess calories and overly rapid growth in large-breed puppies helps.
