Thank you all for your help! I thought that there were different 'types' of Yorkies, like a toy or a teacup, and then Yorkies that are bigger, about 7 lbs. Also, as someone else on this post said, possibly a Pomeranian/Yorkie mix. I'm trying to learn what I can about them, and I did contact a couple of breeders in my area who are waiting for a litter. Thank you for your comments
