Recommendations for creature feature/natural horror films?

I'm looking at doing a series of natural horror films at a local cinema. The main ones I have so far are English language and I'm looking for recommendations for some foreign films to add to the mix.

It needs to be a horror and heavily feature an animal (a real animal not an alien or monster etc).

More obscure and interesting films are very welcome, as well as classics from other cultures we may have missed.

If you know of any that you enjoy, let me know
