I know the feeling!! I saw pictures of the puppies left in the litter I was interested in and brought 2 home! I'd had a yorkie last spring but she was stolen.. I soon realized I couldn't live without the breed, so I couldn't split the sisters up and took both!
The boyfriend had NO clue when we went to pick them up.. lol And now I'm getting a little biewer yorkie girl in February... Definite yorkie fever going on in this house!
