This breed is known to be dangerous due to its strong facade and energetic body. They are usually quiet and loyal, at the same time being independent which makes them quite hard to train.
They are known to have great survival instincts. They are feared due to their capabilities and versatilities of doing things beyond that of a typical dog, such as pulling a sled, herding reindeer and serving as a watch dog.
They tend to become aggressive if they are bored. Hence, they need proper care, exercise and control to avoid aggression.
