Well, I have to report that we found the owner. They posted a sign at the kennel the group boards dogs that don't have foster homes. The dog is apparently 9 years old, is mostly inside but the neighbors were redoing their fence and he must have got out or dug out there. I took him to the Pit Bull rescue to do a evaluation on him she called the owner to get a description to make sure it was their dog. It was, so I left him with her so she could explain the importance of neutering.
