I'm trying to recall the name or source of a short animated film I saw many years ago on the internet.

It concerned a guy who goes into the woods with his dog to a small cabin. It's winter and snowy out. Sometime after they get to the cabin there's a knock at the door (I think). When the guy opens the door, there's no one there. Then he starts hearing strange sounds from outside. Footsteps in the snow, fingernails across the outside walls of the cabin, the doorknob rattles; stuff like that.

If I remember correctly, the dog goes crazy eventually and jumps out a glass window to chase after something. The guy goes after him. Off deeper in the snowy woods, he finds his dog cut in half and surrounded by people standing around it dressed in animal costumes.

It ends with the guy's implied death.

Anyone recognize this story or remember seeing a short net video like this? I think it had a one-word title.
