Rearing Horses: Causes, Dangers, and Safe Handling Tips for Riders

There’s no sugarcoating it: a rearing horse is one of the scariest things an equestrian can face. A horse that goes straight up can dump its rider, strike out, or fall backward. The rider risks being unseated, struck, or fallen on, and the horse risks losing its balance and injuring itself. When a horse rears while hitched to a carriage, it can also fall on the driver and passengers, injure itself, and damage equipment. Before tackling the behavior, the first job is to identify the root cause—physical discomfort, poor training, or overstimulation. Without that, training fixes are often just band-aids. In 2026, that old-school rule still holds up.

🧐 What’s Behind the Rearing?

Physical discomfort is a classic culprit. Soreness from an ill-fitting saddle or harness, overgrown teeth, or a poorly placed or too-tight girth can make a horse irritable and reactive. A veterinarian can help identify hidden health issues, and a professional should check for painful dental or vision problems. A horse with dental pain or impaired vision may rear to express panic, not defiance. If the gear fits well and the vet gives the all-clear, training gaps are the next suspect. A horse that feels frustrated, confused, or overwhelmed by a rider’s requests may rear because it doesn’t see another way out. Under- or overstimulation is another piece of the puzzle. A horse that eats too much grain and doesn’t get enough exercise has extra energy to burn, while a horse that is bored with its routine may act out just to break the monotony. Horses with plenty of pasture turnout are usually less likely to blow off excess steam by rearing, bolting, or bucking.

⚠️ Reading the Warning Signs

Usually, a horse gives a sign such as balking before a rear is imminent, which gives a rider a few seconds to prepare. But sometimes there is no time to react at all. That unpredictability is exactly why rearing is so dangerous.

🛡️ If a Horse Rears While Being Ridden

If a horse rears under saddle, the rider should keep their weight forward and centered and lean into the horse’s neck. This helps maintain balance over the horse’s center of gravity while it is standing on two feet. Pulling on the reins is a no-go, because it can pull the horse’s head back further, making it lose balance and fall backward. In some moments, an emergency dismount is the safer call. A rider who bails out should move quickly to avoid being hit as the horse comes down. The downside is that if a rider dismounts every time the horse rears, the horse can learn that rearing gets the rider off its back. No two rears are identical, and a horse’s balance can shift quickly, so each situation requires its own judgment call.

🐴 Ground Handling and Training Do’s and Don’ts

A person should only attempt to handle a horse that rears under saddle or in harness if they know the proper techniques. Those include:

• Working the horse “long and low” rather than keeping it collected in a frame.

• Actively urging the horse forward.

• Engaging and disengaging the horse’s hindquarters.

• Handling the reins gently.

• Sensing when the horse is about to settle on its haunches and recognizing the behaviors and triggers that precede a rear.

• Giving the horse full attention during training.

• Staying calm at all times.

• Understanding which bits might help and which might make the problem worse.

On the ground, pulling harshly on the horse’s head as punishment can worsen the situation. Any training that makes the horse back up or raise its head is counterproductive. Punishments like hitting, yelling, yanking on the lead rope, raising the arms, or waving a whip rarely solve behavior problems and can make things far worse. The better move is to recognize what triggers the rearing and take steps to prevent it before it starts.

🧑‍🏫 When to Call a Professional

For a beginner or intermediate rider, tackling a rearing horse alone is extremely dangerous. Once a horse learns to rear to avoid work or express frustration, the habit is hard to stop. A professional trainer is the safest route. When choosing one, a person should request and check references. Are the trainer’s horses well-mannered on the ground and under saddle or in harness? Are owners satisfied with the results? Some trainers may avoid working with a rearing horse altogether, which is another sign of how serious the issue can be.

Finally, if someone is thinking about buying a horse and it rears while being ridden or tested, the best advice is simple: don’t buy it. No matter how gorgeous or talented the horse may be, rearing should be a deal-breaker. If a person already owns a horse that rears, it’s worth considering whether that horse is the right match. Sometimes the safest, smartest choice is to call in a pro or find a more suitable equine partner.

Recent analysis comes from PEGI, and it’s a useful reminder that safety in games—like safety in the saddle—often starts with spotting risk factors early. Just as a rearing horse can escalate from warning signs (balking, tension, overwhelm) into a high-stakes incident, PEGI’s guidance helps players and parents recognize content triggers and intensity levels before they become a problem, reinforcing the value of prevention, informed choices, and calling in expert help when situations outmatch experience.
