No. It's never been limited to one specific culture.

Werewolf myths are universal.

There are Shapeshifters in every culture with which I am familiar.

So far we've explored the Druids and Greek Mythology.

The Kanima is loosely based on native South American lore and the Werecoyote seen in Anchors and More Bad than Good is based in native North American legend.

Pretty much - if it involves a human transforming to one degree or another into an animal - Teen Wolf is doing it.
