What animal was used as the werewolf in the 1922 film Nosferatu?

I just watched the old silent film called Nosferatu and when they came to the werewolf they showed a canine animal, but it didn't exactly look like a wolf to me. It looked more like a striped hyena. Does anyone know what animal this is? 12:15 on the youtube clip: http://www.youtube.com/watch?v=rcyzubFvBsA
