The danger of this breed lies in its unpredictable behavior. They can be friendly one minute and then aggressive the next. They have the wolf’s predatory instincts, making this breed potentially dangerous if untrained. They are even more aggressive than wild wolves when provoked. This is why it is not legal to own one in most countries.
