Lost Dog

I have been watching my parents dog, and she wandered off this evening. We had left the door open to enjoy the nice air. When we noticed it was after 11:00 pm. She is a small toy pomeranian. She is tan and black. She is pretty old and can't hear well anymore. Her name is Elise. She can really only hear loud whistles. If you see her or have heard of anyone that may have seen her. Please let us know. Thanks for your help!! If you read this pass it on for me.
