So sweet of you to take her in and try to help find her home. I also wondered if she might belong to an elderly person. Do you live in a small town...do you have a community center that you could leave a flier or what about local churches? Last year, we found an adorable Cairn Terrier wondering close to busy street. I just knew that he had to be lost so we kept him for a week and just kept checking the newspaper. Sure enough, a week later his parents had placed the cutest ad with his picture and wrote...."My name is Spike and I got out of my home....my mommy and daddy miss me so much. Can you help?".
So this ended happily, but it did take a week for it to all fall into place.
I am happy that this precious girl found her way to you!
