Hmmm... I don't know. We don't have a Yorkie *yet* but I wouldn't go through that web site. It doesn't look like a lot of time was invested in it to make sure that the possible future owner of their pups are assured that they have sound breeding practices. Also, most reputable breeders "screen" future owners to make sure that they'll be well taken care of -- as a buyer, it's reassuring to me to be "screened"... I like to know that the breeder really cares about their puppies and finding a good home for them, not just whoever is willing to pay for them. I don't know -- it just seems a bit fishy to me.
Good luck on finding your wonderful yorkie companion...
