Raw Unedited footage of a Great Pyrenees dog attempting to ward off a bull moose. One week after hunting season closed. Great Pyrenees are aggressive with any predators that may harm their flock. Edited footage soon to follow. The Great Pyrenees dog's name is Wynny. Sorry for the shaky footage, I was worried about Wynny's safety, and caught myself following the action with my eyes, instead of the camera lens.
