The Wolf's Lair?

I took this picture in Branféré, if I am not mistaken it is one of the huts for the maned wolves that were there. I might be mistaken ad it could be for some other animal entirely. Maned wolves are not the scariest of wolves: they look like big foxes. Yet this hut looks appropriately sinister. If it isn't a wolf's lair, it should be. When I was a young boy, we used to play a lot of games where the wolf was the central villain, based I guess on old fairy tales. I always imagined the lair to look like this.
