My family plays the sport of paintball and they will leave
wilts or even make you bleed if the gun is to high or if your to close, I have
to say though it will stop that dog from coming after you again if it got shot
by one, just be safe and you might get in trouble with the law if you were
caught shooting an animal with it, and I think it would be to heavy to carry on
horseback and your horse may spook from the rapid shots.
