This little puppy has clearly had a rough start in life, because when you see him in the beginning? The poor pup is homeless, living beside the train tracks, scared of any human interaction. Doggie would growl and bark at anyone who would try to get near him.
Poor guy…luckily the experienced rescue team was able to befriend him and let the puppy know they were here to help and not harm. They finally got the collar on him and carried the dog away.
