Oh where, oh where has my little dog gone?

Saturday Bella decided to make a break. She ran out of the yard and into 24th street. She was hit by a car and then took off running. She has not turned up in any shelter as of yet. We have spent the past two nights combing the neighborhood calling, whistling, talking about cookies loudly. To no avail. It's really quiet around here with out her. No built in alarm to force me out of bed. If you happen to see a black and white dog please call her and see if she likes the name Bella. Ask if she wants a cookie. Hopefully some family found her and she is living the high life. We would just like to know she is.
