Yeah, works fine on pit bulls - try it on a 800lb pissed off brown bear.
tkim - yes, i have been charged. the spray works like gangbusters, in my experience. it was very shocking because i was really familiar with the bears in the area, and they were usually very timid. i must have peed in the wrong bush
as far the pitbull story - man, forgive me, but i laughed hysterically at that story!! i can't believe you sprayed some puppy-yuppie!! thats awesome! the big, high power bear spray is different though. even the small, one handers. higher concentration of irritants, and the stream can extend up to 45 feet, obviously dispersing proportionally to the distance. there is no risk of missing, unless you spray yourself first and blind yourself
