You're welcome. It makes me very sad when I see people come on this board saying 'I got a working line so I wouldn't have to worry about HD' and then their dog has HD and in some cases very bad HD.
I think some unscrupulous breeders will tell people that to sell puppies. It also gets passed around on the internet and then people aren't able to make informed decisions.
In the end, there are good and bad breeders in both lines.
