Good point Nick. Those dogs have many years of evolution to "teach" them how to survive. They know the dangers of the elements and other predators. They know where to sleep so they don't get eaten and most of all they have learned that they must work together to survive. They learn to do all this without learning to sit and roll over on command.  I am with you in that taking a domesticated dog and dropping it in that environment would be like serving an easy dinner.  If some pups were dropped in the area and adopted by the pack it would learn quickly the "rules of the game" or be culled by nature.

My thought is that the human interaction forces our dogs to be lulled into a sense of security and thus makes them unsuitable for the really wild world. Given time and total isolation from man - they could (and have) evolved both in morphology and temperament - ala Wild Dogs.
