Back Pain in Horses

Back pain in horses can range from mild muscular soreness to significant pain caused by injury, disease or problems elsewhere in the body. Because the back plays a central role in transferring movement between the hindquarters and forehand, discomfort can affect performance, behaviour and the way the horse moves.

Back pain should not automatically be assumed to originate in the back itself. Poor saddle fit, muscular strain, underlying orthopaedic problems, foot pain, altered movement and some medical conditions can all contribute.

Important: Persistent, significant or unexplained back pain should be investigated by your veterinary surgeon. Treatment should be based on identifying the underlying cause rather than simply trying to relieve the soreness.

What do we mean by back pain?

The horse's back is a complex structure involving the vertebral column, joints, ligaments, muscles and surrounding soft tissues.

These structures have to stabilise the body while allowing enough movement for the horse to walk, trot, canter, jump, turn and carry a rider.

Pain can develop when one or more of these structures is injured, overloaded or affected by disease. However, soreness can also develop because the horse changes the way it uses its body in response to pain somewhere else.

For example, persistent hindlimb or foot pain may alter movement through the pelvis and back, creating secondary muscular tension or soreness.

This is why finding where the horse is sore is not necessarily the same as finding why the horse is sore.

What might an owner notice?

Signs vary considerably between horses and may be subtle, particularly in the early stages.

An owner might notice:

• sensitivity when grooming or touching the back
• dipping, tightening or moving away when pressure is applied
• reluctance when being saddled
• resentment when the girth is tightened
• difficulty standing still for mounting
• reluctance to move forward
• stiffness during ridden work
• difficulty bending or working evenly on both reins
• problems with transitions
• reduced willingness to engage the hindquarters
• changes in jumping performance
• bucking, kicking out or other behavioural changes during ridden work
• reduced performance without an obvious explanation
• muscle asymmetry or loss of topline
• difficulty rolling, lying down or getting up in more significant cases.

None of these signs proves that the horse has primary back pain. Similar changes can occur with lameness, poor saddle fit, dental discomfort, inappropriate training, behavioural problems and other conditions.

A change from what is normal for the individual horse is often particularly important.

Why does back pain occur?

There is no single cause.

Muscular strain and fatigue

Muscles can become sore following unusual exercise, excessive workload, slipping, jumping, compensatory movement or returning to work too quickly after a period of reduced activity.

Poor physical conditioning can also make fatigue and muscular soreness more likely.

Saddle and equipment problems

An unsuitable or poorly fitting saddle can create abnormal pressure and restrict normal movement.

Saddle fit can also change as a horse gains or loses weight or muscle, meaning a saddle that fitted previously may no longer fit correctly.

Pain elsewhere in the body

This is particularly important.

A horse experiencing foot or limb pain may change the timing and loading of its movement. Those compensatory changes can alter how the pelvis and spine move and how the muscles of the back are used.

Consequently, treating the back without recognising the original source of pain may provide only temporary improvement.

Spinal and joint conditions

Problems affecting the vertebrae and associated joints can cause pain. One well-known example is overriding or impinging dorsal spinous processes, commonly referred to as kissing spines.

However, abnormalities seen on imaging do not always correspond directly with the degree of pain experienced by an individual horse. Veterinary assessment therefore considers the whole clinical picture rather than an X-ray finding in isolation.

Sacroiliac region

Pain associated with the sacroiliac region can affect performance and hindquarter function and may sometimes be perceived by the owner as general back soreness.

Diagnosis can be challenging and requires veterinary investigation.

Injury

Falls, slips, becoming cast, collisions and other traumatic events can damage muscles, ligaments, joints or bone.

Back Pain in Horses — Finding the Cause Matters

Visual concept:
A clean side-profile illustration of a horse with the back and pelvis subtly highlighted. Rather than showing a single red "pain spot", use several possible contributing areas — back, saddle region, hindlimbs and feet — with fine connecting lines towards the back.

Main graphic wording:

BACK PAIN IN HORSES
The sore area may not be where the problem started.

Possible contributors:

Muscles • Saddle fit • Spine • Sacroiliac region • Limbs • Feet • Workload

Primary or secondary back pain?

This distinction can be useful when investigating the problem.

Primary back pain originates within structures of the back itself.

Secondary back pain develops because another problem changes the way the horse moves or uses its body.

For example:

Foot pain → altered loading → altered limb movement → altered pelvic/back movement → muscular soreness

This is one reason a horse with a sore back may need a broader lameness and veterinary assessment rather than treatment being concentrated solely on the painful area.

How is back pain investigated?

Investigation will depend upon the individual horse and the signs being shown.

A veterinary examination may include assessment of:

• posture and muscle development
• areas of heat, swelling or tenderness
• movement of the back
• movement in hand
• lameness
• movement on the lunge
• ridden movement where appropriate
• feet and limb function
• saddle and tack.

Where necessary, further diagnostic procedures may include local anaesthetic techniques and imaging such as radiography or ultrasonography. More advanced investigations may sometimes be required.

The aim is not simply to confirm that the horse's back hurts, but to determine why it hurts.

The importance of saddle fit

Saddle fit deserves particular attention because the horse's shape is not static.

Muscle development, age, workload and changes in body condition can all alter the shape of the horse beneath the saddle.

A horse returning to work, losing weight or developing more topline may therefore require the saddle to be reassessed.

Regular assessment by a suitably qualified saddle fitter can form an important part of preventing and managing some back problems.

Treatment and management

There is no universal treatment for equine back pain.

Management depends on the underlying diagnosis and may involve a combination of veterinary treatment, controlled exercise, rehabilitation, physiotherapy or other appropriately qualified professionals, saddle assessment and changes to training or workload.

Where another painful condition is responsible for compensatory back soreness, that primary condition also needs to be addressed.

Simply repeatedly treating tight or painful muscles without investigating why they are becoming sore risks managing the consequence rather than the cause.

Rehabilitation and returning to work

Rehabilitation should be appropriate to the diagnosis.

Depending on the problem, a programme may aim to progressively restore:

• comfortable movement
• mobility
• muscular strength
• core stability
• coordination
• cardiovascular fitness
• appropriate topline.

Workload should normally increase gradually rather than moving directly from rest to normal ridden exercise.

The horse's feet, saddle, body condition and overall comfort should also be considered during rehabilitation.

Can nutrition help?

Good nutrition supports the horse's general health, muscle function and ability to maintain an appropriate body condition, but supplementation should not be regarded as a treatment for unexplained back pain.

A balanced diet providing adequate energy, good-quality protein, vitamins and minerals is important, particularly for horses undertaking regular work or rehabilitation.

Body condition also matters. Excess weight increases the overall mechanical load carried by the horse, while inadequate nutrition can make it difficult to develop and maintain appropriate muscle.

Where a horse is losing topline or muscle unexpectedly, the reason should be investigated rather than assuming that additional feed or supplementation alone will solve the problem.

When should I call the vet?

Seek veterinary advice where back pain is persistent, recurring, significant or associated with:

• obvious lameness
• sudden deterioration in performance
• marked behavioural change
• severe pain
• weakness or incoordination
• difficulty getting up
• trauma or a fall
• unexplained muscle loss
• reluctance to move
• signs that are becoming progressively worse.

Sudden severe pain or neurological abnormalities require prompt veterinary attention.

Can back pain be prevented?

Not every case can be prevented, but sensible management can reduce some avoidable risks.

Regularly review:

• saddle fit
• hoof care
• body condition
• workload
• fitness
• muscle development
• training intensity
• footing and working surfaces
• recovery following strenuous exercise.

Perhaps most importantly, investigate persistent changes in movement, behaviour or performance rather than repeatedly treating them as isolated muscular soreness.

The JCG Health Hub takeaway

Back pain is a sign, not a diagnosis.

The painful area may be the source of the problem, but it may also be reacting to something happening elsewhere in the horse.

The key questions are therefore not only "Where is my horse sore?" but "Why is my horse sore?"

Finding and addressing the underlying cause gives the horse the best opportunity for comfortable, sustainable movement.
