Malamutes do well outdoors in extreme cold. Closest tame animal related genetically to the wolf. Will escape if not behind a high fence with electric wire. Lots of hair shedding. They need a lot of exercise. The one I had made a military police dog cry, he didn't even growl at it. Will kill an attacker by grabbing them by the throat. Loads of fun in the forest. Will eat 90lbs of dogfood a month. Full size usually 120lbs. Can run 24 miles in 6 hours. Will sleep by the threshold of the door because it prefers the cold. I don't know about other dogs.
