I had a run in with a real jerk this weekend at Birch Bay state CG in Washington state. He would walk his dog, a large full grown German Shepard mix, around the park and and jerk his narrow leather ...
IMO, there's a HUGE difference between giving the leash a quick snap to bring the dog's attention to you - and flipping the dog over. And quite frankly, doing something like that in as public a place as a campground shows that the REAL idiot is on the "looped end of the leash"
