Keep in mind that bear spray is not only effective against bear attacks, bear spray has also been used successfully in protecting against attacks by other wildlife such as cougars / Mountain lions. And although it is generally not advertised as such, bear spray would easily be a deterrent against aggressive dogs, humans, or pretty much any other threat of attack.

The great thing about bear spray is that it is generally allowed in national parks and other wilderness areas where firearms are prohibited.

Important! Keep your bear spray easily accessible. Bear spray in the bottom of your back pack is useless. Whichever brand of bear spray you choose, remember to read and understand the instruction BEFORE you hit the trail.
