Ok, being upset is one thing and asking for help is another. You need to find out what's best for the both of you....so put your anger aside (even though it sounds like you've made up your mind) Anita, that was going to be my next question...are you giving her back to the breeder just to be put down or does the breeder have special people that are willing to take on any of her special issue pups? As for your ortho specialist, most are surgeons and that's what they do, not saying it's not to be the case with your girl but without seeing anything, it's impossible for anyone to say anything or give opinions.
Once again, if you have the ability to post the x-rays and want honest opinions and help then please post the x-rays. My first newf's hips were so bad one popped out of socket, no surgery and he passed a few years later (different issue), so those that say they don't walk on their x-rays couldn't be more correct. You need to share more info to order to get info.
