You don't hit a donkey or a horse with a stick, unless you want your face kicked in. Which actually happened on our ranch, thankfully not to me though.
You ever heard of a horse whip? Do you know how to use them? They're usually over 8 feet long, and when swung, aimed and popped correctly, that pop exceeds the speed of sound, keeping the trainers at a safe distance with a safe advantage.
Wanna try again troll? I literally grew up on a horse ranch, and the proper tools of training horses and donkeys would rip your flesh open.
