She looks like a mix to me, and I know it's a bummer if you paid a lot of money for her. On the other hand, if you check out my avatar, you'll see my little guy, Thor. His color is about as far away from standard as you can get, and people tell me all the time how gorgeous he is. So you can still have a pretty pup.
I'm wondering if you have given a lot of thought to breeding yorkies? Do you have experience breeding them, or a mentor?
