I'm not that surprised. My Pomeranian barks at everyone and everything (including me, even though she's known me her entire life) and has no idea that she's actually small and ill-suited for combat.
Global News reports that Scout, a Pomeranian, lives in black bear country in West Vancouver, British Columbia. When a bear entered the home through an open door, Scout sent the bear scurrying for its life out of the home and then off the property. All six pounds of fury ran at the bear as fast as his feet could carry him in pursuit of the intruding bear.
