As a general rule, supernatural creatures are vulnerable to other supernatural creatures. Vampires can kill werewolves and vice versa. You can add demons, gargoyles, etc. to the list.

Actually, you can remove "supernatural" and just say that monsters are typically capable of hurting each other. Think Frankenstein Meets The Wolf Man or La Maldicion de la Bestia ("Curse of the Beast", aka ''Night of the Howling Beast). ''In the later, a werewolf fights a yeti (spoilers, the yeti is killed and the werewolf mortally wounded).

Ultimately, it all depends on the fictional universe. The Wolfman can only be killed by silver, but The Howling werewolves can be hurt by both silver and fire, and An American Werewolf in London can be killed like any other mundane creature.
