A gigantic demon dog in the folklore of Germany. The name Aufhocker may be translated as 'Leap Upon'- and the creature is often seen to do this to its victims. Once it has leapt upon the back of its prey, it grows heavier and heavier until the person is virtually crushed to death. At other times, it will come upon an unwary traveller and walk for a time by his side, then suddenly rise upon its hind legs until it is tall enough to tear out his throat. It is also occasionally portrayed as a black horse, which invites weary travellers to ride on its back. Once mounted, they find that they cannot dismount, while the horse gallops faster and faster, usually ending by throwing them from its back into deep water or a swamp. The Aufhocker almost always attacks at night, and it is believed that if one can survive until morning, they may escape with their life.
