Lost Dog

I know most of you are dog lovers and will help us. Our neighbor lost her Chihuahua and is desperate to find him. She does a lot of  traveling and always takes her dog with her. Yesterday, she was  sitting on the couch watching TV. She called out for her puppy with no  response, and the back door was open.

She has been putting up signs everywhere. If you see this dog, please let me know and I will  notify her. Your help would be greatly appreciated.
