Wow, I am so so sorry your little girl got out and you have not been able to fine her. It should make us all stop and think about our own "kids" and be sure that we take precautions ourselves so that it does not happen to us. I have three tags on their collers (microchip tag, county license and one I had made up with my husband on the front and me on the back with two different phone numbers). BUT, if someone finds them and decides to keep them and yorkies are a prized possession, your chances are slim unless an honest person found her. Hopefully, they will see she was cared for and make the effort to return it. Again, so so sorry. I do hope she is either found and brought home or she finds her way back home to you.
