a black bear can kill a man (or a dog) with a single swat of its paw.
I suppose anything is possible. But is it realistic? Has it ever happened?
Googling 'man killed by single punch' finds several instance where a person killed a person with one punch. I also find a lion killed a perosn with a single swipe. But not finding anything about a black bear doing this.
Has a black bear killed a man with single swat?
