Horse bucking is one of the most common — and most unnerving — problems riders face. Whether it is a small kick of the hind legs in canter or an explosive, head-down bronc that sends you into orbit, bucking is always the horse telling you something. The key to stopping it is working out what that something is.
This guide covers why horses buck, how to tell the difference between pain-related and behavioural bucking, and the practical steps you can take to fix the problem safely.

What Is Bucking?
Bucking is when a horse lowers its head and kicks its hind legs — and sometimes all four feet — off the ground. In a full buck, the horse’s back arches, the head drops between the knees, and the hindquarters are thrown upward with significant force. It is a natural movement: wild horses buck to dislodge predators, and domestic horses buck in the field as play. The problem arises when it happens under saddle. In rodeo, horses known as “broncos” or “broncs” are deliberately bred and encouraged to buck as athletes; this guide is concerned only with bucking as an unwanted behaviour in everyday riding horses.
The severity varies enormously. A single, half-hearted kick in the transition to canter is very different from a sustained, rodeo-style bucking fit. Understanding the type and intensity of the buck helps you identify the cause — and therefore the solution.
Bucking vs Crow-Hopping
Many riders describe their horse as “bucking” when it is actually crow-hopping — a smaller, less explosive movement where the horse stiffens its back and hops forward with its hind legs kicking out slightly. The difference matters because the causes are often different:
- True bucking: Head drops low, back arches, hindquarters thrown high. Often caused by pain, fear, or a strong evasion response. Difficult to sit and potentially dangerous.
- Crow-hopping: Head stays relatively level, back stiffens rather than arches, hind legs kick out but the horse stays relatively grounded. Often caused by laziness, resistance to leg aids, cold-backed behaviour, or mild discomfort. Annoying but usually manageable.
If your horse is genuinely bucking — head between knees, back arching, all four feet off the ground — always rule out pain first. If it is crow-hopping, the cause is more likely behavioural, though a vet check is still worthwhile.
Why Horses Buck: The Main Causes
Pain and Physical Discomfort
Pain is the most common reason horses buck, and the first thing to rule out. Common pain-related causes include:
- Poorly fitting saddle: A saddle that pinches, bridges, or sits on the spine creates pressure points that worsen under the rider’s weight. Many horses tolerate the discomfort at walk and trot but buck in canter when the saddle’s movement against the back intensifies. Have your saddle checked by a qualified fitter — not just once, but every 6–12 months as your horse’s shape changes.
- Back pain: Kissing spines, sacroiliac problems, muscle spasms, and spinal misalignment can all cause bucking. A horse that is sore through its back will often buck during transitions, when asked to work in an outline, or when the rider sits deeply. A veterinary examination including X-rays or ultrasound may be needed to diagnose the problem.
- Tight or pinching girth: A girth that is overtightened, positioned too far forward, or rubbing against sensitive skin behind the elbow can cause bucking, particularly soon after mounting or during the first few strides.
- Dental pain: Sharp enamel points, wolf teeth, or bit seat issues cause mouth pain that the horse may express by tossing its head and bucking when rein pressure is applied. A dental check every 6–12 months is essential.
- Hind limb or hock pain: Arthritis, bone spavin, or stifle problems cause pain when the horse engages its hindquarters — exactly the movement required for canter transitions. The resulting buck is the horse’s way of avoiding that engagement.
- Gastric ulcers: Equine Gastric Ulcer Syndrome (EGUS) affects an estimated 60–90% of horses in work. Ulcer pain can cause girthiness, sensitivity to leg pressure, and bucking, particularly when the horse is asked to go forward strongly.
Cold-Backed Behaviour
Some horses buck in the first few minutes of being ridden — often during the initial trot or first canter. This is commonly described as being “cold-backed” and may be caused by a combination of mild back discomfort and muscle stiffness. These horses often settle once they have warmed up, but the behaviour should not be dismissed as “just what he does” — it usually indicates low-grade discomfort that deserves investigation.
Fear and Anxiety
A frightened horse may buck as part of a flight response. Sudden noises, unfamiliar objects, or being asked to do something that worries them — such as approaching water or leaving the group — can trigger a fear-based buck. This type of bucking is usually accompanied by tension, head-raising, and attempts to spin or bolt.
Horses that have had traumatic experiences under saddle may also develop anticipatory anxiety. If a horse has been punished for refusing a jump, for example, it may begin bucking on approach to fences as a pre-emptive defence.
Resistance and Evasion
Some horses learn that bucking gets them out of work. If a horse bucks and the rider stops asking for the canter, or gets off, or puts the horse back to walk, the horse has been rewarded. Over time, this creates a habitual bucker — one that bucks not because of pain or fear, but because it works.
Resistance bucking tends to be lower intensity (crow-hopping rather than full bucking), is predictable (always at the same point in the session), and improves when the horse is ridden by a more confident, effective rider.
Excess Energy and Lack of Turnout
Horses that are stabled for long periods, overfed concentrates relative to their workload, or under-exercised are far more likely to buck. The buck is simply an expression of pent-up energy — the horse equivalent of a person fidgeting after sitting at a desk all day. Increasing turnout time, reducing hard feed, and providing adequate forage often reduces this type of bucking significantly.
Rider Imbalance
An unbalanced rider can inadvertently cause bucking by bumping the horse’s back, gripping with the lower legs (which the horse interprets as a “go” aid while the hands are saying “stop”), or collapsing through one hip. This conflicting pressure confuses the horse, and some respond by bucking. Improving your own position — through lessons on a well-schooled horse, lunge lessons, or core strength work — can make a remarkable difference.
How to Stop a Horse from Bucking
Step 1: Rule Out Pain
Before addressing behaviour, eliminate all physical causes. This means:
- Professional saddle fit check
- Veterinary examination of the back, hind limbs, and teeth
- Gastric ulcer scope (gastroscopy) if ulcers are suspected
- Check the girth, bit, and all tack for fit and condition
Do not skip this step. It is tempting to assume the horse is “just naughty,” but research consistently shows that a high proportion of behavioural problems in horses have an underlying pain component. Treating a pain-based problem as a training issue makes it worse, not better.
Step 2: Review Management
- Increase turnout time — horses need movement
- Reduce concentrate feed if the horse is not in hard work
- Ensure adequate forage (minimum 1.5% of bodyweight in dry matter per day)
- Warm the horse up properly before asking for canter work — 15–20 minutes of active walk and trot, not a quick walk around the arena
Step 3: Improve Groundwork
If the bucking is behavioural, groundwork rebuilds respect and communication without the risk of being thrown. Useful exercises include:
- Lunging: Assess the horse’s movement and willingness to go forward on a circle before getting on. If the horse is also bucking on the lunge, the problem is almost certainly physical.
- Lateral work in-hand: Shoulder-in, leg-yield, and turn on the haunches from the ground teach the horse to respond to pressure cues without the complication of carrying a rider.
- Desensitisation: For fear-based buckers, systematic desensitisation to the triggers (flapping objects, noise, leg contact) reduces the flight response over time.
Step 4: Ride Through It Correctly
If you are confident the bucking is behavioural and you are a competent rider:
- Keep the head up. A horse cannot buck effectively with its head elevated. If you feel the horse dropping its head to buck, use a firm upward rein aid to lift the head and immediately send the horse forward with your legs. Bridge your reins for extra security.
- Ride forward. Bucking requires the horse to slow down and round its back. Sending the horse actively forward — into a strong trot or canter — makes it mechanically difficult to buck. Never pull back, as this lowers the head and makes bucking easier.
- Do not punish after the fact. Smacking a horse after it bucks teaches it nothing useful — the horse does not connect the punishment with the buck. Instead, correct in the moment by driving forward and then asking again for the movement that triggered the buck.
What to Do If Your Horse Bucks While Riding
If your horse bucks unexpectedly while you are riding, your immediate priorities are safety and control:
- Sit deep and lean back slightly. A forward-tipping rider is much easier to unseat. Press your seat bones down and anchor your lower leg.
- Lift the horse’s head. Take a firm contact and pull one rein upward and to the side (a pulley rein). This prevents the horse from getting its head down for a sustained buck.
- Drive forward immediately. Use strong leg aids to push the horse into a forward trot or canter. Forward movement is the enemy of bucking.
- Use a one-rein stop. If the horse is bucking in a straight line and you cannot regain control, slide one hand down the rein and bring it firmly towards your hip, bending the horse’s head round to one side. This puts the horse onto a tight circle, disengages the hindquarters, and makes it mechanically impossible to keep bucking. The one-rein stop is the single most useful emergency tool a rider has — practise it at walk and trot so it is automatic before you ever need it in earnest.
- Do not bail out unless unsafe. If you can stay on, ride through it and then ask for the movement again calmly. Getting off rewards the behaviour.
When to Call a Professional
Seek professional help if:
- The bucking is violent and you are at risk of serious injury
- The horse has suddenly started bucking when it never did before — this strongly suggests pain
- You have ruled out pain and the horse continues to buck despite consistent, correct training
- You are a novice rider and do not have the skills to ride through a buck safely
- The horse bucks with every rider, regardless of experience level
A qualified BHS-accredited instructor or an experienced behaviourist can assess both horse and rider and develop a tailored training plan. If the problem is pain-related, a veterinarian with a specialism in equine sports medicine is the right first call.
Preventing Bucking Long-Term
Once you have addressed the immediate cause, these habits help prevent bucking from returning:
- Regular tack checks: Have your saddle refitted every 6–12 months. Check girth, numnah, and bit condition regularly.
- Routine veterinary and dental care: Teeth every 6–12 months, back checks annually, and prompt investigation of any change in behaviour.
- Adequate turnout and forage: A horse that moves freely and eats adequate fibre is calmer, healthier, and less likely to express frustration under saddle.
- Consistent, progressive training: Avoid asking for more than the horse is physically or mentally ready to give. Rushing training creates resistance; patient, incremental work builds confidence.
- Warm up properly: Every session should begin with 15–20 minutes of walk and trot work before asking for anything demanding. A cold-backed horse that is allowed to warm up gradually may never buck at all.
- Rider fitness and position: Your own balance and core strength directly affect your horse. Investing in your riding skills is one of the most effective ways to prevent bucking.
Frequently Asked Questions
Why does my horse only buck in canter?
Canter requires more engagement of the back and hindquarters than walk or trot, so it exposes discomfort that may not be apparent at slower gaits. Common causes include back pain, kissing spines, poorly fitting saddles, hind limb issues (particularly hocks and stifles), and gastric ulcers. A horse that bucks exclusively in canter should always be examined by a vet before any behavioural approach is taken.
Is it safe to ride a horse that bucks?
It depends on the severity and frequency. Occasional, low-level crow-hopping from a known trigger (cold-backed, fresh from the field) can be managed by an experienced rider. Violent, sustained bucking that unseat riders is genuinely dangerous and should not be ridden through until the cause has been identified and addressed. If in doubt, get professional help — the risk of a serious fall is not worth taking.
Can a horse be trained out of bucking?
If the bucking is behavioural (not pain-related), yes — most horses can be trained out of it through consistent, correct riding and management. The key is never rewarding the buck (by stopping work or dismounting) and always sending the horse forward through the moment. However, if the root cause is pain, no amount of training will fix it. Treat the pain first, then address any learned behaviour that remains.
Do certain breeds buck more than others?
There is no strong evidence that specific breeds are inherently more prone to bucking. However, hotter breeds such as Thoroughbreds and Arabians tend to be more reactive and may express discomfort or excitement through bucking more readily than heavier, calmer breeds. Management — particularly turnout, feeding, and workload — has far more influence on bucking behaviour than breed alone.
Should I use a stronger bit to stop bucking?
No. A stronger bit does not address the cause of bucking and may make it worse by adding mouth pain to whatever else is bothering the horse. If the horse bucks because of pain, a stronger bit adds to the problem. If the horse bucks from evasion, a stronger bit gives it more to evade against. Focus on finding and treating the cause, not on escalating the equipment.
Do horses buck when they’re happy?
Yes. Bucking is not always a problem — horses frequently buck, leap, and kick out from sheer exuberance, particularly when first turned out, in cold weather, or when galloping in company. This playful bucking in the field is normal, healthy behaviour and nothing to worry about. It only becomes a concern when it happens under saddle, where it puts the rider at risk. The skill lies in telling the difference between a fresh, happy horse letting off steam and a horse bucking because something is wrong.
Should you punish a horse for bucking?
No. Punishing a horse after it bucks does not work — the horse cannot connect a smack with an action that is already over, and if the bucking is caused by pain or fear, punishment makes the underlying problem worse. The correct response is to send the horse forward through the moment, keep its head up, and calmly ask again for the movement that triggered the buck. Always address the cause, never the symptom.
