I have to agree with the other members. I would NEVER consider breeding a dog that was purchased from a miller, for the reasons mentioned. I'm sure that she is a lovely girl, both in her pictures and in person, but just because a dog is precious does not mean she is without genetic fault that could be passed on to future generations. Even if SHE shows no signs or sypmtoms, they *could* be lying dormant somewhere down the line waiting to rear their ugly heads again. It would be a HUGE risk that could cause truly heartbreaking results for both you and any potential new owners. Furthermore, it is impossible to tell if a dog is of a quality that should be bred when they are just puppies. Even the most experienced and accomplished show breeders can't make that determinatin. No one is suggesting that to offend you or insult your little angel...just to share their insight and express their concerns regarding the situation.
I truly do hope you will reconsider.
That being said, I am very thankful that she is no longer living in the horrendous conditions with the puppy miller. She deserves to live the life of the spoiled princess she is.
