Is he chipped and registered? I'm sure he'll be found and returned to you. I have a feeling you are more nervous than your dog. Just take it easy and keep checking with contacts in that area.

Hope your pup turns up aj. Our dog escaped last week and some kind person had taken him to the rspca so we were able to pick him up the next day. He now has an rspca tag on his collar. If he escapes again they will know who he belongs too. Great organisation, they are able to rehome most of the lost/abandoned dogs here in Townsville.
