I'm sorry, I don't have any advice or information for you, but I'm sure someone will. My husband once had a rottie with HD, and he did have surgery when he was younger--he's not home now, of course, but I can ask him later.

I just want to let you know that you and your kids are in my thoughts and prayers. I'm glad to hear that she isn't in any pain right now, and both Shiloh and Killian have the best most devoted mommy a doggie could ever wish for.
