Some animals seem to have all of the luck, or maybe their own personal guardian angel.
At the time I was working as a vet tech and was walking the dogs prior to surgery early in the morning. I saw a large Rottweiler hanging around behind the clinic, watching me. He had a collar on, so I grabbed a leash and approached him slowly. He started wagging his stubby tail, and willingly came with me to the clinic. While we called around trying to find his owner, the vet did a basic workup - she was concerned because he was thin and seemed extremely tired.
