I agree with the others, check out the YTCA referral list, I will be forever thankful to the people at YorkieTalk who recommended the Yorkshire Terrier Club of America. Before I found YorkieTalk, I responded to a few newspaper ads, and heard back from a missionary in Africa,
I’m so naïve, I really believed it at the time! I always recommend going for a home visit, and getting to know the breeder. Please support breeders who do health testing, and understand the importance of breeding healthy dogs. I don't know how old your daughter is, but remember the Yorkshire Terrier is first of all, a terrier, and they aren't a purse puppy; they need lots of training and patience, and they require quite a commitment. Here are some of the YTCA breeders from Washington.
