@Logicfest -- you might not want to look elsewhere if you are the type that likes to take a dog that might have been abused, give it a good home and restore the critter to its natural state of having fun in an environment where it is comfortable and loved. I have taken in a couple of dogs that were skittish because they have been abused and it was a lot of fun transforming them from nervous, distrustful animals to dogs that are comfortable in a loving environment.
By the way, be warned about Yorkies -- they tend to bark quite a bit. As you said, they are terriers. The problem with a Yorkie's bark is that it's more of a high-pitched yipe. That's not enough to scare a burglar, but it is enough to wake up everyone in your home in the middle of the night.
