BM, DJD1 is NOT A DEGENERATING DISEASE. It does NOT GET WORSE. She has all the health test records for her dog.
Obviously, yes, there are some things that show up later in life, after a dog has been bred. This is something she knew about before she decided to breed her dogs. This is something that, so far, HAS NOT BEEN PASSED DOWN, and more than likely there will be a few pups that have it, but so far, none do. All her puppy buyers were, I'm SURE, informed of the parents health testing results. Both are OUTSTANDING dogs in their breed, and I do NOT see why they shouldn't be passing down those genes. If I was interested in a Rottweiler, Red would be the very FIRST person I would go to. On the same token, if I wanted a Borzoi I would stay VERY FAR AWAY from you and your lines.
BM, you are sitting on a very very high horse. One day, if the fall off doesn't kill you, you may just LEARN something.
