...you see that isn't caged.
You're a genius.
That's a completely retarded deduction to make from the story. This should be called " yet another reason for every law abiding American citizen to carry a firearm." Un-caged dogs aren't typically dangerous unless they form a pack. These animals were obviously reverting to their natural instincts. They did exactly what any hungry wolf would do if they stumbled on an old sickly moose. Imagine your a hungry wolf that's just taken down a moose and suddenly a second sickly moose rushes into the clearing. Its like fucking Christmas for any natural predator.
