Simple explanation. Bear spray works...on bears...because they have an olfactory system that is hundreds of times more sensitive than that of the pit bull you sprayed. Simple as that.View attachment 271070
I used bear spray on a pit bull that was killing my neighbor's dog,it did not work as well as I believed it would.It did temporarily dive on the ground and rub it's nose in the dirt,but,it was right back up within about 10 seconds.Maybe I should have used the whole can? I thought,at the time, if it can stop a charging bear,a dog would not need a full blast.
