I'm so sorry you lost Pixie. I agree with the other YT'ers. $7000 is way too much to pay for a puppy. Also, I asked a lot of questions when I bought Lucy. I called the breeder and asked if I could just come out and look and he was perfectly agreeable. He took me on a tour of his facilities and answered all questions. Your new baby is out there.
Good luck in your search
Kim and Lucy
