Apols if slightly OT, but just to reply re elbow dysplasia, if you equate it to hip scores, because of the much smaller range, a grade of 0:1 is equivalent to a hip score of approx 0:13 - so you can see straight away how uneven that appears?
I have a bitch who has higher elbow grades 2:1, she was hit by a car as a pup, and I do believe environmental factors played a large part in any possible deterioration of her elbows, without going into reams of my life, my ex believed the best way to make a dog sleep through the night was to walk the legs off it. There is such a lot more weight on the front end of a dog of that size and build, it's easy to imagine with all the daft twists and turns they can be prone to doing more damage, possibly. Add to that, a vet that was new to taking hip and elbow plates, and I think we may have ended up with the worst end of the proverbial stick in her case. However, as much as I *think* the grades may not actually reflect her actual true elbow state, I did stick by the health test results, and decided to have her spayed, just in case anyone wondered ;)
