Unlike other dogs, no one considers dingoes to be man’s best friend. These fluffy pups are highly intelligent but equally merciless. Their rotatable paws and necks allow them to hunt better than most other canines, and a single dingo can kill animals as big as a kangaroo. When traveling in packs, the females designate an alpha who proves her dominance by eating all of the other female dingoes' newborn offspring. After watching Zoo, pretty much any animal that travels in packs should make you a little nervous.
