Section 1 Overview
Rearing is one of the most dangerous behaviors a riding horse can develop, yet it's often more about fear or resistance than genuine aggression. A horse that rears is rising onto their hind legs, often high enough to threaten balance or fall backward. This is a serious safety issue because a horse that loses balance while rearing can fall backward onto the rider or onto themselves. A horse that rears repeatedly becomes a liability both for the rider and for everyone around them. Understanding why rearing happens is the first step toward fixing it.
Unlike bucking or bolting, which are relatively forward-directed behaviors, rearing requires the horse to shift weight backward. This unusual movement pattern suggests the horse is trying to avoid something they perceive as threatening coming from the front. Rearing can come from fear, resistance to forward motion, or physical pain. Some horses rear when they're anxious or trapped. Some horses rear when they're asked to move forward into something they fear. Some horses rear because they've learned that rearing gets them out of work. Understanding which cause applies to your specific horse is essential.
Rearing is learned and unlearned behavior. Young horses might rear occasionally as part of play or exploration, but this behavior isn't persistent or dangerous. A horse that rears repeatedly when ridden has learned that rearing accomplishes something from their perspective. Maybe it gets them out of work. Maybe it relieves pressure they don't understand. Maybe it expresses anxiety or fear. Fixing rearing requires identifying what the horse is trying to accomplish and addressing that underlying driver.
Most solutions that seem logical actually make rearing worse. Pulling back hard on the reins when a horse rears can pull them over backward. Harsh punishment teaches the horse that forward motion leads to punishment, making them more reluctant to move forward and more likely to rear in the future. Aggressive training approaches create defensiveness that makes the behavior worse. The only solutions that actually work are addressing underlying causes so the horse doesn't feel the need to rear.
This guide covers understanding the causes of rearing, assessing whether the behavior is dangerous, implementing solutions, and preventing rearing from developing. The goal is developing a horse that moves forward willingly without resorting to rearing.
Section 2 Fundamentals
Rearing comes from specific motivations in the horse's mind. Fear is one cause; a horse that's afraid of moving forward might rear as an avoidance mechanism. Resistance to unclear communication is another cause; a horse that doesn't understand what you're asking and feels trapped might rear. Physical pain is another significant cause; a horse with back soreness, bit problems, or other painful conditions might rear when pressure triggers pain. Anxiety and learned behavior complete the picture; a horse that's learned rearing gets them out of work will rear when asked to work.
The danger of rearing varies based on height, frequency, and what triggers it. A horse that rears occasionally when startled is less dangerous than a horse that rears violently every time asked to move forward. A horse that rears but comes down under control is less dangerous than a horse that loses balance or falls backward. Understanding your specific horse's rearing pattern helps you assess the actual danger and the appropriate response.
Horse psychology during rearing involves the horse's perception that forward motion is dangerous or unacceptable. They're not being deliberately difficult; they're avoiding what they perceive as a threat. A horse that fears something ahead will rear rather than move toward it. A horse in pain will rear rather than move into the pain. A horse that doesn't understand what's being asked and feels pressure will rear as an escalation of resistance. Punishment teaches the horse that moving forward leads to negative consequences, which makes them even more reluctant to go forward.
Your role in addressing rearing is identifying the underlying cause rather than simply suppressing the symptom. Fixing rearing without addressing why it happens leaves the underlying problem unsolved and often makes the behavior worse over time. You're not trying to force the horse to stop rearing; you're trying to make rearing unnecessary by addressing what's driving it.
Equipment assessment matters because bit problems, saddle fit, or other tack issues can cause pain that leads to rearing. Before assuming the problem is behavioral, have your veterinarian check for soundness and a professional evaluate your tack fit. Many horses labeled as rearers have actually been in pain. Fixing the pain usually eliminates the behavior.
Section 3 Technique And Method
Addressing rearing starts with identifying the specific cause for your horse. Is your horse afraid of something specific, or do they rear whenever asked to move forward? Does rearing happen with certain riders but not others, suggesting the problem is rider communication? Does the horse show signs of pain when rearing or when moving? The answer to these questions points toward the actual cause.
For horses that rear from fear, the solution involves desensitization to whatever triggers the fear. If the horse fears moving toward a specific object, spend time approaching that object from the ground. Lead the horse closer and closer to the object without forcing them past their comfort level. When the horse calmly stands near the object, that's success. Repeat this process until the horse can approach the object calmly. Then ask for forward motion only after the horse is calm. This teaches the horse that forward motion toward the object is safe.
For horses that rear from unclear communication, the solution involves simplifying communication. Return to basic forward motion exercises at the walk. Use clear, consistent leg pressure paired with release when the horse moves forward. Don't punish rearing; simply address the forward motion training. As the horse learns that leg pressure means "move forward" and that moving forward stops the pressure, clarity improves. Once forward motion is understood at the walk, progress to trotting, then cantering with the same clarity.
For horses that rear from physical pain, the solution is eliminating the pain source. Have a veterinarian evaluate for soreness, lameness, or other physical issues. Have your saddle fitted professionally. Have the bit and bridle evaluated for fit. Check teeth for problems. Once the pain is resolved, much of the resistance often disappears naturally. Training can resume once the horse is physically comfortable.
For horses that rear from anxiety, the solution involves reducing overall anxiety through consistent routine, patience, and gradual exposure to work. These horses often benefit from more groundwork and less riding pressure initially. They need to learn that you're not going to force them into scary situations. Establish trust first, then gradually increase demands. Sessions should be short and successful rather than long and frustrating.
For horses that have learned rearing gets them out of work, the solution is refusal to allow rearing to accomplish that goal. When the horse rears, don't stop working. Use strategies like half-turns or backing, which prevent the horse from rearing high and teach them that rearing doesn't stop the work. The key is never rewarding rearing with relief from pressure. This requires calm, firm consistency.
Session structure for retraining a rearer focuses on removing fear and building confidence in forward motion. Start with groundwork where the horse moves forward willingly. Progress to riding at a walk with clear, gentle communication. Build sessions slowly and stop on success. Many retraining sessions should involve more groundwork and walking than riding, with the goal of establishing confidence.
Section 4 Common Challenges
The most common mistake in addressing rearing is using punitive approaches that increase the horse's defensiveness. Hitting a rearing horse, pulling hard on the reins, or using harsh bits and spurs teaches the horse that forward motion is dangerous and punishment is inevitable. These horses rear more as they become more defensive. The correction requires switching to patient, communication-based approaches.
Another common issue is misdiagnosing the cause. A horse that rears might be doing so for multiple reasons, or the cause might be different than the most obvious explanation. A horse that appears to be resisting might actually be in pain. A horse that seems lazy might actually be anxious. Proper diagnosis through careful observation and veterinary evaluation is essential before implementing solutions.
Some riders struggle with the fear of a rearing horse and become overly cautious, which communicates anxiety to the horse and makes rearing more likely. A rider who tenses when the horse approaches a situation that previously triggered rearing teaches the horse that the situation is indeed dangerous. Staying calm and confident, even when concerned, is important. If you're too frightened to ride the horse calmly, working with a professional trainer might be safer.
Another challenge is knowing when the rearing is a safety emergency versus a training problem. A horse that rears once when spooked is different from a horse that rears violently multiple times every session. Understanding the severity helps you decide whether to address it with basic training or professional help. Severe rearing is dangerous and warrants professional involvement.
Some horses develop rearing as part of anxiety disorders or trauma responses. These horses need more than standard training; they need help managing their anxiety. They might eventually learn to move forward, but they require patience, consistent routine, and often benefit from reduced environmental stress.
Section 5 Safety Considerations
Safety with a rearing horse means understanding the real danger. A horse that falls backward from a rear can crush the rider. A horse that loses balance while rearing can fall on the rider. These are serious injury risks, including death. Taking rearing seriously is appropriate and important. Riding a horse with a rearing problem requires confidence and skill. If you're not experienced with dangerous behaviors, professional training is essential.
Wear appropriate protective gear including a helmet at minimum. A protective vest might be appropriate for severe rearing. Riding in an enclosed arena rather than open spaces gives you more control if a rear happens. Never ride a severely rearing horse in situations where a fall could cause injury, like near obstacles or on steep terrain.
Never pull back hard on the reins if the horse rears. This can tip the horse over backward, which is dangerous for both you and the horse. Instead, lean forward if possible or use turning techniques to avoid the rear. Learning proper techniques for handling rearing if it happens is important safety knowledge.
Know when to ask for professional help. If a horse rears severely, if you don't have experience managing dangerous behaviors, or if your fear is limiting your ability to ride calmly, working with a trainer experienced in rearing is the right choice. This isn't admitting failure; it's being smart about safety.
Recognize when rearing indicates a serious problem that might not be solvable. Some horses with severe anxiety disorders, PTSD, or chronic pain conditions might rear despite best training efforts. At some point, you might need to decide whether the horse is safe to ride or whether they need a different purpose.
Section 6 Progression And Tips
Progress with a rearing horse looks like decreasing frequency and decreasing height of rears. A horse that reared constantly might rear only occasionally. A horse that reared high and lost balance might rear slightly. Over time, with proper training and removal of underlying causes, most horses stop rearing entirely. Success is measured by the horse moving forward calmly without rearing.
Measuring progress includes noticing how the horse responds to situations that previously triggered rearing. A horse that previously reared at the gate might walk through calmly. A horse that reared when asked to move forward might move forward willingly. These behavioral changes indicate real progress.
A pro tip for retraining is using groundwork extensively. A horse that moves forward willingly from the ground learns the concept of "go forward when asked." Translating that understanding to under saddle then becomes possible. Some trainers do extensive groundwork before riding a rearing horse, establishing the forward motion behavior first.
Another useful tip is riding a rearing horse only when you're calm and confident. If you're anxious, the horse picks up that anxiety and rearing becomes more likely. Groundwork sessions where you build your confidence through working with the horse without riding can help you develop the calm confidence necessary for safe riding.
Final thoughts on rearing emphasize that this is a serious behavior requiring serious attention. However, most rearing has identifiable causes that can be addressed through patient training and sometimes professional help. A horse that learns to move forward confidently and calmly becomes much safer and more pleasant. The investment in fixing rearing properly pays off in a horse that's safe to ride for years to come.
