Yorkie Breeders in Washington State

Your best bet is to go to a dog show (google dog shows in Washington state) and talk to the breeders, owners and handlers there.
But I must warn you they will likely not place a Yorkie in a home with children under 8 or so. They are fragile, high strung little dogs and often come with health problems, like many other small specialty breeds.
You may want to talk to the breeders directly about other options if your kids are younger, they can be very helpful in pointing you in the right direction!

Yeah, we just got a pup (not a yorkie though) and if you want an actual PUPPY (as in less than 6 months old) - they are not easy to find in shelters. And most rescues in our area (Seattle) will not adopt dogs to families with small children (under 8 years). So a breeder is pretty much the only option.

We ended up buying from a breeder after checking shelters. We found ours via an ad on ebay classifieds, but the newspaper (online) also has plenty of breeders advertising. I saw LOTS of yorkies when I was looking.
Just be smart and use common sense: ask to meet the pup before you pay, look where they are raised, is the area clean (bedding/poop picked up etc.), have they seen a vet, been wormed and vaccinated, do the look healthy...etc, etc.

It took us about 4 months to find our perfect pup...
Good luck!

Lots of Yorkies on Petfinder!

You might also want to try a Yorkie rescue group.

In my opinion, there are no reputable breeders. And yorkies? Oh my. Not a great dog with kids, and a dog that can have lots of health problems. Keep looking at rescue groups. You can find a nicer, much healthier dog there -- even a yorkie mix would be better than a purebred.

AKC has a breeder listing, http://www.akc.org/classified/search/index.cfm

but check petfinder.com
I found both of my dogs and my cat on petfinder , rescue dogs make the BEST dogs. And if you get a yorkie mix they actually live longer and have less health problems.
