try using a martingale.
Have the rider get off the horse immediately and try getting a more experienced rider to train the horse, or turn out the horse before riding to get that energy out. or more training with you to get the basics.
If your horse is really determined to rear, probably not. A martingale is not a good solution however, because it does not solve the problem, it just covers it up, kind of like a bandaid sort of. If you have checked for any paint he horse might be in, like a poor fitting saddle, a wolf tooth, ect. What works really well with rearing horses is when they rear up, pop them right between the ears to make them think they hit their head on something. How long they have been rearing will determine how many times you have to do it before they stop rearing for fear of hitting themselves.
A horse can not REAR up if he is moving forward. Rearing is a very bad and dangerous habit and should be discouraged. Most horses that develop the habit often do it in response to a rider being too heavy handed and hurting the horses' mouth.
"Whoa" is the classic command to stop a horse.
Make the horse want to do what you ask it to and make the horse understand you are the leader. To be the leader, move the horses feet forward, left, right and backwards. To make the horse want to do what you are asking it, make what you are asking it be the easiest thing to do. Like, if you want the horse to stop, lope the horse until he is begging to stop, and then, when you give the slightest signal to stop, the horse will stop on a dime.
The actual quote is "stop beating a dead horse" stop wasteing time on a pointless activity.
It means to stop the horse with the ropes.
There isn't much you can do to stop a horse from coming into season. This is a natural occurrence.
Have you ever heard of dressage? They basically make the horse dance. You can teach the horse reining manuvers, (sliding stop, lead changes, run-downs, spins, etc), cow cutting, barrel racing, trail riding, and many other disciplines. Groundwork is very important to teach your horse, and once you have ground work down pat, you can even teach your horse tricks like smile, yes, and more advanced tricks like bow, lay down and even rearing up!
This has happened alot to me, and from personal experience, I can truthfully say there is no way to really make a young horse stop bucking when it's running. The only thing you can do is try to hold on and pull their head up every chance you get.
A weanling is a young animal, such as a horse, that has recently been weaned from its mother's milk and is transitioning to a diet of solid food. Weaning typically occurs around 4-6 months of age for many animals.
You can start by allowing the horse to rest if you want it to stop pulling on the reins. It takes time for the horse to understand the movements and actions of the rider.
