My Sister-in-law heard a similar noise coming from a car trunk parked beside an old gas station close to downtown HOU. She got the owner to open the trunk only to revel a very similar dog without hair (mange) and a rope around the neck. She took him home, got him healed and named him Lucky.
That was over 9 years ago. He is alive and well enjoying retirement in New Mexico with his rescuer.
Here is the old-joke she remembered that she selected the name from....enjoy.
