A clear case of not having the right tool for the right job......... Video Shows Man Shoot A Charging Grizzly Bear! - YouTube
unless it's hungry, or just mad!.. then it will break into your house, and kill you!.. and if you have kids outside in your yard, can they run fast enough into the house to escape the charging bear, maybe they will just freeze from fright, and get killed!..If you see a bear running around outside, shut up, close the doors and stay safe. It will go away.
it's best to have at least 2 dogs, one attacks from the front, while the other attacks from the rear. it's so confusing, the bear don't have a chance, and runs away..My dog (at the time) ran bears out of the yard, even brown bears, no problem at all.
The bears will run, until they get to the woods, there they stop and face the dog, and my dog was smart enough to NOT go into the woods, so problem solved!
