There is -- or at least was -- a Silky that lived across the street. And now I know there is Snickers, the little Houdini dog that I got out of traffic a few months ago.
One of my neighbors has a chihuahua and the gal behind me has a rabid dachsund. (Dog is forever in ATTACK mode.)
Other than that, there are a few bigger dogs, but no other Yorkies that I know of.
