They say, it's not the size of the dog in the fight that matters but the size of the fight in the dog that decides the winner. Sumit Mamgain, by that account, was a very big dog when he decided to take on a wild predator to save his cousin from the jaws of death. In 2015, Sumit - a 15 year old from Uttarakhand along with his older cousin Ritesh were grazing cattle in a field. Out of nowhere a leopard pounced on them and attacked Ritesh.
