i don't let them. of course you can't always stop a horse mid-buck. and sometimes a young horse is just playing and i don't want to ruin their play drive, but when it comes to preparing for safe riding, i don't let them buck. read on.
there is more than one way to not allow bucking. the first is simple. on the ground (preferably not riding), ask your horse to back up, go forward, go sideways, or any other thing other than buck, when you see him trying to buck. maybe the first time they buck, i don't do anything about it, because it may not become a bad habit. but
