Hammer dogs tend to get this also, specifically in the left rear knee.
This might not be a popular opinion with vets or conformation folks, but my own view would be that the dog just has a little more work to do to win![]()
Ch Hammer actually carried several structural faults, but it still didn't prevent him from whipping and curring-out dogs with better conformation 8-)
IMO, the worst conformation fault at all is not conforming to the APBT standard of gameness ...
