If you mess with a moose, you get the hoof. That's what two Colorado women learned when they were out for a walk with their dogs.

The Gilpin County, Colo. women were near a subdivision when the moose suddenly appeared. "All of a sudden he looked at me grunted and then charged," Jackqueline Boron, 50, told Denver's KDVR.

Boron was stomped several times by the moose, sustaining four broken ribs, extensive bruising to her body, and a wound on her leg required 15 stitches. Her friend, Ellen Marie Divis, was also hurt in the fracas.

Although the women said their dogs had not been barking, their presence alone might have been enough. Moose and dogs are a combustible combination. The dogs bark and spook the moose, and it doesn't help that a dog, to a moose, resembles the latter's only predator in the wild, a wolf.

Generally, moose don't attack humans without first feeling provoked, and people are more likely to be injured by a moose during a vehicle accident. In Alaska, for example, the moose number more than 100,000, and that state can see 10 or so moose-related human injuries, and a couple of fatalities, per year.
