My mum as had two a malamute and a siberian. Amazingly loyal, intelegent and protective dogs. But a lot of work as they have so much energy.
Kotuko was nearly a wolf beautiful but wild, he hunted and everything killed 2 sheep 4 rabbits some of which he partialy ate before we got hold of him. (The sheep were when he escaped once, farm only asked for value as they saw him and said it was a clean kill. Fortunatly they were very understanding)
But when my mum was burgled the police think they fled when he confronted them, they found a couple of kitchen knives dropped in the house so we suspect they chose not to take him on!
Truely amazing dogs but demand a special sort of owner, they are not your average pooch.
