Welcome to YorkieTalk! We're in Seattle too, if you want, you can check out a Seattle Yorkie Meetup group sometime (
http://yorkie.meetup.com/258) which meets every third Saturday. You can see all kinds of purebred Yorkies (from smaller to bigger, different colors, etc) and talk with their parents about them.
We got our two from the same breeder in Everett, WA, but at different times. There's good and bad in getting them at the same time. The good is they grow up together and one won't get testy when a new one comes into the home, the bad is it's probably almost twice as much work initially. You can PM me if you are interested in our Everett breeder's name and phone number.
