Those are grey wolves who are more friendly with a photographer than expected. The secret is in not having FEAR, animals like dogs and wolves SMELL the fear in humans when near them; when humans have fear they give up a certain odor that the sensitive noses of the animals pick it up but human because their sense of smell is not so strong like those animals are not able to pick it up. When those animals smell the FEAR they attack for kill. No fear means> no smell> means no dogs or wolves attack or bites at least -unless the animal is too crazy one.
