That has crossed my mind! I have wanted to call the new owner to find out, out of curiosity. The worst part of my story is that the owner of the sire is one of the most well-known judges in the country. And yet she put out a sire whose tests were misleading because she had him tested in the country from which he was imported and then provided those test results which are structured differently to those here, hence being misleading (long story, the owner of the boy with elbow dysplasia investigated -- she is a vet). And... after a couple of years of owning him, I heard she (the judge) sold him to someone else, so... clearly she decided he was not actually as good as she proclaimed when I called her when I was searching for a puppy. Getting a registered dog (with the Kennel Union) apparently doesn't mean much here -- the Kennel Union does not exclude a dog with health issues from being registered; it uses other criteria such as: the parents were previously registered. I need to reread the criteria (it has been a while), but to a novice such as myself, I assumed it meant certain health guarantees. But apparently it does not.
