Much like many of the dogs we have on this list, the Husky is quick, fast, and full of energy. Huskies are also mainly used as sled dogs too, because they can be able to run through the snow and all. The breed does have a history of being somewhat of a blue collar dog, they aren’t known to be sociable with other dogs, or animals in general. Still, that doesn’t mean they’re not dangerous, because they are. Unlike several of the dogs on this list, Huskies have claimed quite a number of human lives. Such incidents happened as recently as 1998, when the dogs were accountable for fatally attacking 15 people.
