It is a sad video with a heartwarming ending. Watch as a poor puppy, severely mistreated by a homeless man, is found sitting helpless in a riverbed. His leg was intentionally cut, and he had been thrown down into the river some 30-feet intentionally.
A bystander, with his camera rolling, is called to action. Seeing the situation, he jumps into action to rescue the puppy sitting motionless below. He climbs over the fence running along the river and slowly approaches the puppy, so as not to alarm or frighten it further.
