What's the difference between an Elk and a Moose? Oh anywhere between 300-750 pounds and a whole heck of a lot of attitude! There aren't many predators willing to take on a Bull Moose all by their lonesome and only the very hungry pack of Wolves would attempt it either. Even a Big Old Brown Bear will go another direction unless driven by extremes. In all honesty, you wouldn't want a Cow Moose angry with your much either.
