Werewolves, wolves, and dogs - Canidae
The Werewolf - Virlupus monstrum
Close relatives: The werewolves closest relatives are believed to be the timber wolf, gray wolf, dire wolf, and the crocotta.
Note: Ancient Egyptian accounts of Werewolf-like creatures (e.g. Anubis, Set) were likely not of this species, which is exclusively European and American. For the Ancient Egyptian, Greek, and numerous other cultural depictions of "dog-men", see Aliens & SUpernatural Monsters.
The crocotta - Virlupus frendo
Close relatives: The crocotta's close relatives are the werewolf, spotted hyena, cave wolf, and the African wild dog.
Mongooses & small mammals - Mustelidae
Dragon Weasel/Hydrus - Mustela ichneumon/Mustela hydrus
They may be two species but they are almost exactly the same thing, only the dragon weasel eats dragons, and the hydrus eats crocodiles.
Big cats - Felidae
The beast of Bodmin Moor/Exmoor - Panthera pinguis
Though they go by different names, we believe that they are both the same animal. Some have theorized that it may be the world's first black cougar, however this new species is much more closely related to the jaguar.

The maltese tiger - Panthera tigris
