history: I left the front door unlocked this morning and our dog got out. I can't believe I would be so careless.  I left the front door unlocked this morning and our dog got out. I can't believe I would be so careless. I'm sure that he will turn up soon. I really hope that you find him. We have been driving around all evening looking for him. He really is my best friend.
current: Maybe check your local animal shelters? Sometimes they are taken there by people who find them. 
next: We will have to go there next, hopefully he is chilling there.
