One main element is the wolf - girl connection. It's often that the girl has some sort of special bond with wolves, either being raised by them or having a supernatural link.
The setting of the story usually plays an important role. Most likely it's in a forest or a wild area where wolves can roam freely. The isolation and mystery of such a place add to the scariness. And then there's the girl herself. Her behavior, which is often different from normal humans, like having a more animal - like instinct, is also a key element.
In 'the wolf girl scary story', the element of the unknown is very prominent. We don't really know what the girl is fully capable of. Is she more wolf or more human? Her appearance might also be part of the scare factor. Maybe she has some wolf - like features, such as sharp teeth or hairy body parts. Also, the way she hunts or preys on others, if that's part of the story, is a major element. It gives the feeling that no one is safe when she's around, especially in the wilderness where she has the advantage.
