Dakotah, relax - Manchesters is trying to help, and I agree with her. She was not "mean" when first suggesting that you THINK about what you are doing. It would be wise to listen to her advice, doing so may save you a lot of heartbreak in the future. (I speak from experience - I have a dog that is the product of poor breeding, and on some days, he is miserable. It's horrible for an owner to watch their dog in pain.) Ripley's breeder said her dogs were healthy, and I believed her because I honestly didn't care about the health of the parents at the time! I cared about the cute little puppy in my lap.
Don't turn a blind eye to the quality of the breeder, just because you want a puppy now.
I might even be mistaken, perhaps the breeder HAS done the necessary health tests and just failed to mention them to you, but that seems highly unlikely to me. (Probably the first thing I'd mention would be the fact that the parents were healthy, but that's just me.) Ask her about it - better to be safe than sorry!
