Overview:Dogs are known as man's best friend, but now canines are striking fear into many who report attacks by predatory packs. Originally descended from wolves, domesticated dogs were brought to the United States 12,000 years ago and used as aggressive protectors. Today, more and more dogs are being turned loose on the streets and returning to their wild roots. These feral dogs are attacking people. Now, MonsterQuest launches a search to follow these ferals, using state of the art cameras to uncover where they live and how dangerous they are to man.
