Lúthien deserves some credit for making them fit, though.

In some mythology that is exactly what a werewolf is. . . a person who wears the skin of a wolf. Not as a fur or coat of course, when they put this on they would actually "become" a wolf. This seems an awful lot like what Luthien and Beren did. . .
