Oh, no, no and hell no. I just looked at her website and my opinion is you should walk away. Can somebody else please look at the link to moms on the puppy page and tell me if something looks off with "Sarah." Perhaps it is the camera angle, but that poor baby girl looks like a baboon. I'm sorry to offend, but most of her moms and dads look off to me, not standard at all. And Tatum's coat is very red.
OP, if the appearance of your Yorkie is important to you (and I'm guessing it is) you should really look for a breeder that is breeding to the standard set by the YTCA. Regarding coat, I have a soft (cotton) coated Yorkie and it broke my heart when I realized it, which wasn't until he was maybe 6 months old (I got him at 12 weeks). I don't know if experienced breeders can tell at 8-12 weeks what the quality of a puppy's coat will be, but I sure couldn't. It just wasn't fair to my Nicco to try to grow a long coat so he has a puppy cut. It mats so easily and no amount of grooming or product will change that.
