A 400-lb sow black bear? That would be a real whopper for a black bear sow.
They look bigger when they want to harm you.
I really doubt that the attack happen for 15 minutes or that the bear was 400lbs.
I seen bear hounds ripped really bad with just short contact with a bear.
Doesn’t look like the bear made contact with the dogs owner ether.
The amount of damage a bear can inflict in seconds is amazing.
They all look really good for having fought off a bear.
She is in FL no reason for going unarmed.
