Why Does My Horse Crib, Weave or Stall-Walk?

By Dr Duncan Houston

Crib-biting can destroy stable doors. Weaving can make a horse look unable to settle. Stall-walking can continue until the bedding is flattened and the horse is sweating.

It is tempting to call these behaviours bad habits, stable vices or simple boredom. None of those explanations is clinically useful enough.

Crib-biting, windsucking, weaving and box-walking are recognised equine stereotypies. They most commonly develop when a horse’s feeding, movement or social needs conflict with the environment available to them. Once established, the behaviour can become deeply ingrained and may persist even after management improves.

Quick Answer

Equine stereotypies are repetitive and relatively fixed behaviours such as crib-biting, windsucking, weaving and stall-walking.

They are not usually deliberate misbehaviour, and horses are unlikely to simply copy them from another horse. Management should focus on forage access, social contact, turnout, predictable routines and identifying pain or gastrointestinal disease rather than punishment or mechanical suppression alone. A new, rapidly worsening or physically harmful behaviour requires veterinary assessment.

Equine Stereotypies at a Glance

Behaviour	What it looks like	Main concern
Crib-biting	The horse grasps a fixed object with the incisors, flexes the neck and produces a characteristic grunt	Colic association, dental wear, property damage and underlying management stress
Windsucking	Similar neck flexion and air movement without needing to grasp an object	Similar concerns to crib-biting
Weaving	Rhythmic side-to-side movement of the head and neck, usually with alternating weight between the forelimbs	Social frustration, confinement, reduced rest and possible physical wear
Box-walking or stall-walking	Repeated walking around the stable along the same route	Frustration, separation distress, feeding anticipation, weight loss or failure to rest
Other repetitive behaviours	Pawing, wood-chewing, tongue movements, headshaking or wall-kicking	These are not automatically stereotypies and may have different behavioural or medical causes

Crib-biting, weaving and box-walking are the classic equine stereotypies described in behavioural research. Wood-chewing and several other repetitive behaviours are often classified separately because their pattern, motivation and underlying causes may be different. (ScienceDirect)

What Is an Equine Stereotypy?

A stereotypy is a repetitive, relatively unchanging pattern of behaviour with no obvious immediate goal.

The word obvious matters. The behaviour may appear pointless to an observer, but that does not mean it is biologically meaningless.

Stereotypies may develop when a horse repeatedly experiences:

• Frustration

• Social restriction

• Forage restriction

• Confinement

• Unpredictable feeding

• Inability to perform a strongly motivated behaviour

• Repeated stress during development

Some evidence suggests that performing a stereotypy may reduce arousal or frustration in certain horses. Once the behavioural and neurological pattern becomes established, the horse may continue performing it even when the original trigger is no longer present. (ScienceDirect)

This is why I avoid calling stereotypies “stable vices.” The word vice implies choice, moral fault or deliberate disobedience. The horse is not plotting the demise of the stable door. It is expressing a behaviour that has developed through a combination of environment, learning, physiology and individual susceptibility.

Which Behaviours Are True Stereotypies?

Crib-Biting

During crib-biting, the horse usually:

1. Grips a stable door, fence, feeder or another fixed surface with the incisors

2. Pulls backwards

3. Contracts the lower neck muscles

4. Draws air into the upper oesophagus

5. Produces a characteristic grunt

The behaviour is often performed immediately before or after concentrate feeding, during confinement or when the horse is anticipating a predictable event.

Windsucking

Windsucking involves a similar neck movement and characteristic sound, but the horse does not need to grasp an object first.

Owners and researchers sometimes use the terms crib-biting and windsucking interchangeably, so studies commonly group them together as crib-biting or windsucking behaviour.

Weaving

A weaving horse moves the head and neck repeatedly from side to side while shifting weight between the forelimbs.

It commonly occurs:

• At the stable door

• When other horses leave

• Before feeding

• When turnout is expected

• During prolonged confinement

• When the horse has limited social contact

Some horses weave only during anticipation. Others perform it for long periods.

Box-Walking or Stall-Walking

A box-walking horse repeatedly follows the same route around the stable.

The movement may be circular, rectangular or follow the walls. Some horses walk mainly before feeding or turnout, while severely affected horses may continue for prolonged periods and struggle to eat, rest or maintain weight.

Is Wood-Chewing a Stereotypy?

Not necessarily.

Wood-chewing involves biting and consuming or stripping wood without the characteristic neck flexion and grunt of crib-biting. It may represent redirected foraging behaviour, insufficient forage access, exploration, learned behaviour or environmental frustration.

A four-year study of young horses treated wood-chewing separately from stereotypies such as crib-biting, weaving and box-walking. Wood-chewing was particularly associated with post-weaning stable or barn housing rather than pasture management. (Beva)

The distinction matters because covering the stable in metal may stop access to the wood but does not correct inadequate forage, dental discomfort or the management problem causing the chewing.

Pawing, tongue movements, licking, headshaking and wall-kicking should also not automatically be labelled stereotypies. Their meaning depends on the pattern, trigger, frequency and the horse’s physical health.

Why Do Horses Develop Stereotypies?

There is rarely one single cause.

The behaviour generally develops through an interaction between management, early experience, feeding, social environment, individual temperament and biological susceptibility.

Weaning and Early Management

The period around weaning appears particularly important.

In a four-year prospective study, weaning through confinement in a stable or barn was associated with more than twice the rate of abnormal behaviour compared with paddock weaning. Continued barn housing after weaning increased the risk further, while concentrate feeding after weaning was associated with approximately four times the rate of crib-biting development. (Beva)

This does not mean every stable-weaned foal will develop a stereotypy. It means abrupt social separation, dietary change and confinement occurring together can create a high-risk developmental environment.

A safer weaning program generally preserves:

• Contact with familiar horses

• Access to forage

• Free movement

• Predictable handling

• Gradual dietary change

• A stable social group

Forage Restriction and Concentrate Feeding

Horses are adapted to consume forage for many hours each day.

Long periods without forage may create hunger, gastric acidity, oral frustration and anticipatory behaviour. Large concentrate meals can also produce a rapid change in feeding motivation and gastrointestinal physiology.

Epidemiological studies have repeatedly associated stereotypies with restricted roughage, concentrate feeding and limited pasture access. A Swiss population study concluded that prevention strategies should emphasise substantial roughage, daily free movement and tactile contact with other horses while limiting unnecessary concentrate feeding. (Beva)

Established crib-biting may not disappear simply because more forage is provided. A small feeding study found that unrestricted hay did not eliminate crib-biting in horses with an established stereotypy, although sufficient forage remains important for gastrointestinal health and for preventing further management-related frustration. (ScienceDirect)

Social Isolation

Visual contact through bars is not always equivalent to meaningful social contact.

Horses are strongly motivated to interact with other horses through touching, grooming, resting nearby and coordinated movement.

A 2025 study divided 20 individually stabled horses into an isolated group and a group allowed one hour of paired social interaction each day. After four months, horses receiving social contact showed fewer stereotyped and repetitive behaviours in their stables, fewer negative behaviours during grooming and a more optimistic response during cognitive testing. (ScienceDirect)

Another study found that purpose-designed social boxes substantially increased positive physical interactions between neighbouring stallions without causing serious injuries during the observation period. (PubMed)

This does not mean every horse can safely be released into a group immediately. Injury, infectious disease, rehabilitation restrictions and individual compatibility still matter. The goal is to provide the safest achievable level of meaningful contact.

Confinement and Lack of Free Movement

Turnout provides more than exercise.

It allows horses to choose where to stand, graze, investigate, interact and move away from social pressure. Horses kept without daily pasture or paddock access have shown greater odds of crib-biting, weaving and box-walking in observational studies. (Beva)

Stable enrichment may help, but it cannot fully replace the horse’s basic need for movement, forage and social contact.

A study of 187 individually boxed horses found only limited benefits from factors such as straw bedding, a window and reduced concentrate feeding. No simple stable modification completely corrected the wider welfare restrictions associated with long-term individual confinement. (MDPI)

Feeding Anticipation and Predictability

Some horses perform stereotypies primarily before:

• Feeding

• Turnout

• Exercise

• Other horses leaving or returning

• A familiar person arriving

• Competition or transport

In these horses, the behaviour may be closely linked to anticipation and frustration rather than occurring continuously.

The answer is not always to make the entire routine unpredictable. Predictability can help horses feel secure. The useful change is reducing long waits, competition, abrupt transitions and repeated exposure to a cue that occurs long before the expected event.

For example, preparing feed in front of a stalled horse for 30 minutes every evening can turn one meal into a lengthy frustration experiment.

Pain and Gastrointestinal Discomfort

Gastrointestinal discomfort may contribute to crib-biting in some horses, particularly around weaning.

A study comparing 19 young horses that had recently started crib-biting with 16 non-crib-biting horses found significantly greater gastric inflammation and ulceration in the crib-biting group. An antacid diet improved the stomach findings, although crib-biting declined in many foals regardless of diet. (BVA Journals)

This finding suggests an association between early crib-biting and gastrointestinal disturbance. It does not prove that gastric ulcers cause every case, that crib-biting causes every ulcer or that acid suppression will cure an established stereotypy.

Pain elsewhere may also increase restlessness, repetitive movement or oral behaviour. Dental disease, lameness, back pain and other medical problems must be considered, especially when the behaviour begins suddenly in an adult horse.

Temperament and Individual Sensitivity

Two horses can experience the same environment but respond differently.

Studies have identified differences in reactivity and tactile sensitivity between some stereotypic and non-stereotypic horses. These differences may reflect temperament, previous experience or changes in neurological pathways associated with chronic stress and repeated behaviour. (PubMed)

This does not make the horse defective. It means some individuals are more vulnerable to a particular management challenge.

Are Equine Stereotypies Genetic?

There appears to be some inherited susceptibility, but the evidence is not simple.

Thoroughbreds have had higher crib-biting prevalence than several other breeds in population studies. A United States survey reported crib-biting in 13.3% of Thoroughbreds compared with an overall population prevalence of 4.4%. (Beva)

A Finnhorse study produced a high preliminary heritability estimate of 0.68. In contrast, a later Chilean horse study estimated low heritability and concluded that environmental factors may explain a greater proportion of the behaviour in that population. (ScienceDirect)

A candidate-gene study involving 98 crib-biting horses and 135 controls also failed to identify a major association with the genes examined. (ScienceDirect)

The practical conclusion is:

• Genetics may influence susceptibility

• Management strongly affects whether that susceptibility is expressed

• No single crib-biting gene has been identified

• Breed is a risk marker, not a diagnosis

• A family history may be worth considering in breeding decisions

Current evidence does not justify a universal rule that every horse displaying a stereotypy must be excluded from breeding. The whole horse, family pattern, welfare implications and likely management of the offspring should be considered.

Can Horses Learn Cribbing From Another Horse?

There is little evidence that stereotypies are contagious.

In the United States crib-biting survey, only about 1% of horses were reported to begin crib-biting after exposure to another crib-biting horse. The degree of contact with affected horses was not associated with crib-biting risk. (Beva)

Several horses in one yard may still develop similar behaviour because they share:

• The same feeding system

• Similar periods without forage

• The same turnout restrictions

• Similar training pressure

• Limited social contact

• Related bloodlines

The shared environment is a more plausible explanation than copying in most cases.

Isolating a crib-biting horse to protect other horses may therefore increase social stress without preventing anything.

Does a Stereotypy Mean the Horse Is Currently Stressed?

It is a welfare warning, but it is not a precise live stress meter.

The behaviour may reflect:

• A current management problem

• A previous environment

• An established habit

• An individual coping response

• A combination of these factors

Some studies have found that cortisol decreases after a stereotypy or that horses performing crib-biting during a frustrating task have lower salivary cortisol and fewer frustration behaviours. This supports the theory that the behaviour can have a coping function in some contexts. (Cambridge University Press & Assessment)

Other studies have found no consistent difference in plasma or faecal cortisol between stereotypic and non-stereotypic horses. (PubMed)

The correct interpretation is not that crib-biting is good for the horse. It is that simply stopping the visible behaviour does not necessarily improve the underlying emotional state.

A horse physically prevented from weaving may look quieter while remaining just as frustrated.

Are Stereotypies Harmful to Horses?

The degree of harm depends on the behaviour, its frequency and the individual horse.

The behaviour itself may produce physical consequences. More importantly, it may reveal that the horse’s feeding, movement or social needs are not being met.

Crib-Biting and Colic

Crib-biting and windsucking have repeatedly been associated with colic.

A matched case-control study found a significant association between crib-biting or windsucking and a history of colic, although no particular type or severity of colic accounted for the overall relationship. (Beva)

Crib-biting has also been strongly associated with epiploic foramen entrapment, a specific form of small-intestinal strangulation requiring emergency surgery. The association is clinically important, but it does not prove that crib-biting directly causes the intestine to become entrapped. (Open Research Surrey)

Research into recurrent colic has also identified crib-biting and, in one study, weaving as risk markers for recurrence. (Beva)

The old explanation that crib-biting causes colic simply because the horse fills its gastrointestinal tract with swallowed air is inadequate. Research indicates that only limited aerophagia occurs, and the relationship probably involves more complex differences in gastrointestinal function, management and neurophysiology. (Springer Nature Link)

What Owners Should Do

A crib-biting horse should not be expected to colic constantly, but the horse’s colic risk deserves attention.

Monitor:

• Appetite

• Water intake

• Manure production

• Body condition

• Frequency of crib-biting

• Changes in forage

• Time spent stabled

• Previous colic episodes

New abdominal discomfort should not be dismissed as “just the cribbing horse being dramatic.”

Crib-Biting and Gastric Ulcers

Crib-biting and gastric ulceration can occur together, particularly in young horses around weaning.

The relationship may run in several directions:

• Gastrointestinal discomfort may increase motivation to crib

• The same management factors may contribute to both conditions

• Crib-biting may alter gastrointestinal physiology

• The two may coexist without one directly causing the other

Gastroscopy is the only way to confirm and grade gastric ulceration accurately. Treating a horse with omeprazole solely because they crib does not establish a diagnosis and may not change an established stereotypy. (BVA Journals)

Dental Wear and Oral Injury

Repeatedly gripping a hard surface can wear the incisors or damage the mouth in some horses.

Check for:

• Uneven incisor wear

• Fractured teeth

• Gingival injury

• Difficulty grasping forage

• Quidding

• Dropping feed

• Weight loss

• Oral odour

Crib-biting has also been associated with temporohyoid osteoarthropathy in a retrospective population, although the direction of the relationship remains uncertain. (Beva)

A horse showing abnormal eating, facial swelling, quidding or sudden oral behaviour should receive a complete veterinary dental examination. (AAEP)

Weight Loss and Poor Body Condition

A horse that spends prolonged periods crib-biting, weaving or stall-walking may spend less time eating and resting.

Weight loss may also indicate:

• Dental disease

• Gastric ulceration

• Chronic pain

• Poor forage access

• Social exclusion

• Malabsorption

• Chronic infection

• Endocrine disease

• Another underlying medical condition

Do not assume the stereotypy itself explains every kilogram the horse loses.

Weaving, Stall-Walking and Physical Wear

The physical consequences of weaving and stall-walking are sometimes overstated.

Severely affected horses may develop:

• Uneven hoof wear

• Fatigue

• Reduced rest

• Loss of condition

• Recurrent minor injuries

• Swelling or soreness associated with repetitive movement

• Damage from striking walls, doors or partitions

The stronger clinical concern is often what the behaviour says about the horse’s management and whether the horse can eat, drink, lie down and rest normally.

How Worried Should You Be?

Risk level	What it looks like	What to do
Lower risk	Long-standing, occasional behaviour; normal appetite, body condition, manure, movement and rest	Record the pattern and review management at the next routine veterinary visit
Moderate risk	Behaviour increasing around feeding, confinement or social separation; minor dental wear, property damage or reduced rest	Improve forage, turnout and social contact, and arrange veterinary review if it persists
High risk	New onset in an adult, rapid escalation, weight loss, recurrent colic, oral injury, lameness or inability to settle	Arrange prompt veterinary examination and a full management assessment
Critical	Colic, collapse, neurological signs, severe injury, uncontrolled bleeding, inability to eat or drink, or severe exhaustion	Treat as an emergency

Not Every Repetitive Behaviour Is a Stereotypy

This distinction is especially important when a behaviour appears suddenly.

Behaviour	Possible non-stereotypic explanations
Pawing	Feeding anticipation, frustration, colic, limb pain or discomfort while tied
Repeated circling	Stall-walking, but also neurological disease, visual impairment, pain or confusion
Headshaking	Flies, eye disease, ear disease, dental pain, tack discomfort or trigeminal-mediated headshaking
Tongue or lip movements	Oral lesions, dental discomfort, bit pressure, feeding anticipation or learned behaviour
Wood-chewing	Redirected foraging, insufficient forage, exploration, dental disease or gastrointestinal discomfort
Wall-kicking	Feeding anticipation, social conflict, separation distress, pain or learned attention-seeking
Fence-walking	Separation from companions, unsuitable turnout, resource frustration or inability to access shelter, water or forage

Sudden one-directional circling, loss of balance, head pressing, altered awareness or collisions with objects should be treated as possible neurological disease rather than ordinary box-walking. Potentially infectious neurological cases require prompt veterinary investigation and appropriate biosecurity. (AAEP)

When Is This an Emergency?

A stereotypy by itself is rarely an emergency. The physical signs occurring alongside it may be.

Contact a veterinarian immediately if the horse develops:

• Repeated rolling

• Looking at or kicking the abdomen

• Persistent pawing with reduced appetite

• Little or no manure

• Abdominal distension

• Profuse sweating

• Collapse

• Severe or non-weight-bearing lameness

• A deep wound or uncontrolled bleeding

• Seizures

• Incoordination

• Sudden blindness

• Head pressing

• Persistent circling in one direction

• Difficulty swallowing

• Feed or saliva coming from the nostrils

• Severe weight loss or weakness

• A rectal temperature outside the horse’s normal range with depression

Pawing and repetitive movement can be early colic signs. UC Davis advises contacting a veterinarian immediately when abdominal pain is accompanied by rolling, flank-watching, kicking at the belly, reduced appetite or failure to pass manure. (UC Davis Veterinary Medicine)

What To Do Right Now

1. Stop exercise and remove the horse from immediate hazards.

2. Call your veterinarian.

3. Do not punish or restrain the behaviour aggressively.

4. Record temperature, heart rate, appetite and manure production if it is safe to do so.

5. Take a video from a safe distance.

6. Do not administer sedatives, pain relief, ulcer medication or calming products unless directed.

7. Do not force a neurologically abnormal or painful horse to walk repeatedly.

How Will a Veterinarian Assess the Behaviour?

There is no single blood test for equine stereotypies.

Diagnosis begins with establishing exactly what the horse is doing, when it happens and whether a medical condition could be producing a similar pattern.

Your veterinarian may ask:

• When did the behaviour begin?

• Did it start around weaning, a move, transport or a management change?

• Does it occur before or after feeding?

• Is it worse when other horses leave?

• How many hours is the horse stabled?

• How long is the horse without forage?

• Has the frequency changed?

• Has the horse lost weight?

• Has the horse had colic?

• Does the horse stop when turned out?

• Can the horse eat, drink and rest normally?

• Has anyone tried a collar, bar, muzzle or medication?

A veterinary examination may include:

• Body-condition assessment

• Oral and dental examination

• Gastrointestinal assessment

• Lameness examination

• Neurological examination

• Eye examination

• Review of diet and forage

• Review of turnout and social arrangements

• Gastroscopy when gastric ulceration is suspected

• Blood tests or imaging when other disease is possible

Videos taken at the actual time and location of the behaviour are extremely helpful. Horses have a charming habit of behaving perfectly once the veterinarian arrives.

What Should You Do if Your Horse Has a Stereotypy?

1. Record the Pattern

For seven to fourteen days, record:

• Time of day

• Behaviour performed

• Approximate duration

• Feeding times

• Turnout

• Exercise

• Horses nearby

• Changes in routine

• Appetite

• Water intake

• Manure

• Any colic or pain signs

The trigger often becomes clearer when the behaviour is viewed as a timeline rather than a frustrating isolated event.

2. Assess the Horse’s Physical Health

Arrange veterinary examination when the behaviour is:

• New

• Increasing

• Associated with weight loss

• Associated with recurrent colic

• Interfering with eating or resting

• Causing injury

• Accompanied by abnormal movement or awareness

An established crib-biting horse still needs routine dental care and investigation of any gastrointestinal signs. Do not assume every future problem belongs to the same behavioural diagnosis.

3. Increase Safe Forage Access

Aim to minimise long periods without forage.

Practical options include:

• More frequent forage provision

• Several hay stations

• Slow feeders

• Lower-energy forage when weight control is needed

• Feeding forage before concentrate

• Splitting concentrate into smaller meals

• Reducing unnecessary concentrate

• Using a forage analysis to balance the ration properly

For an overweight or insulin-dysregulated horse, unlimited access to rich pasture or high-sugar hay may be unsafe. The goal is prolonged, controlled forage intake using an appropriate low-sugar forage plan, not metabolic chaos served in a hay net.

4. Review Concentrate Feeding

Ask whether the horse genuinely needs the current quantity of grain, sweet feed or pellets.

Base the decision on:

• Workload

• Body condition

• Forage quality

• Age

• Reproductive status

• Metabolic health

• Muscle and weight goals

Reduce concentrate gradually rather than making an abrupt dietary change.

Concentrate feeding after weaning has been associated with increased crib-biting development, and established crib-biters often perform the behaviour most intensely around concentrate feeding. (Beva)

5. Increase Turnout and Free Movement

Provide daily turnout whenever medically and practically possible.

Turnout should offer:

• Safe footing

• Adequate space

• Shade and shelter

• Water

• Forage

• Suitable companions

• Fencing appropriate for the horse

• Enough room to avoid conflict

A small individual pen may provide fresh air without satisfying the horse’s need for meaningful movement or social interaction. The quality of turnout matters as much as the word appearing on the stable schedule.

6. Improve Social Contact

The strongest option is usually compatible group or pair turnout.

Where this is not possible, consider:

• Adjacent turnout

• Stable partitions allowing safe tactile contact

• A social box

• A calm neighbour

• Supervised shared exercise

• A stable design allowing greater visual and physical interaction

Introduce horses safely and complete infectious-disease quarantine before allowing direct contact.

Even limited regular interaction may improve welfare. In the 2025 study, one hour of paired social contact per day reduced stereotyped and repetitive behaviours in individually housed horses. (ScienceDirect)

7. Reduce Feeding Frustration

If the behaviour begins while feed is being prepared:

• Prepare feed out of sight where possible

• Avoid lengthy delays after feeding cues begin

• Feed forage before concentrate

• Use a consistent feeding order

• Prevent one horse from watching every other horse eat first

• Distribute forage before the yard becomes highly aroused

Predictability is useful. Thirty minutes of bucket-rattling theatre is less useful.

8. Use Enrichment Intelligently

Enrichment may help, but it should supplement rather than replace forage, movement and social contact.

Options include:

• Several forage locations

• Safe browse

• Purpose-built slow feeders

• Stable windows

• Rotating safe objects

• Scratching surfaces

• Food-search opportunities

• Mirrors for selected weaving horses

A small study involving six established weaving horses found that a stable mirror significantly reduced weaving during the five-week treatment period. The sample was small, so mirrors should be treated as one possible aid rather than a guaranteed cure. They must be shatter-resistant and installed safely. (ScienceDirect)

9. Make the Environment Physically Safe

For a crib-biting horse:

• Remove sharp metal edges

• Repair splintered timber

• Secure feeders and buckets

• Protect electrical cables

• Check incisor wear

• Avoid toxic paints and coatings

For a weaving or stall-walking horse:

• Improve footing

• Remove projections

• Protect knees and hocks from sharp surfaces

• Ensure doors and partitions are secure

• Provide adequate space

• Check hoof wear regularly

Do not apply caustic chemicals, irritants or electrical deterrents to cribbing surfaces.

10. Reassess Objectively

Review the horse after two to four weeks of meaningful management changes.

Measure:

• Frequency and duration of behaviour

• Body weight

• Body condition

• Appetite

• Manure

• Rest

• Injuries

• Colic episodes

• Ability to interact normally

• Time spent eating forage

A reduction is encouraging. Complete disappearance is not required before management is considered beneficial.

Established stereotypies frequently persist after the original environmental problem improves, so success should also be judged by the horse’s physical health and overall welfare. (ScienceDirect)

Managing Crib-Biting and Windsucking

Priorities include:

1. Review forage and concentrate feeding.

2. Investigate recurrent colic, poor condition or ulcer signs.

3. Check the incisors and oral cavity.

4. Increase turnout and social contact.

5. Identify feeding and confinement triggers.

6. Remove dangerous cribbing surfaces.

7. Monitor whether the horse can eat and rest normally.

Some owners provide a safer designated cribbing surface rather than attempting to eliminate every opportunity. This may reduce damage to dangerous structures, but it should be combined with management changes and dental monitoring.

Managing Weaving

Weaving is commonly linked to social separation and anticipation.

Management may include:

• More turnout

• Pair or group housing

• A horse in the adjacent stable

• Safer tactile contact

• A stable window

• A properly installed mirror

• Less waiting before turnout or feeding

• More distributed forage

• Moving the horse away from a high-traffic or highly stimulating location

Blocking the stable door with weaving bars may shift the behaviour further back into the stall without resolving the motivation.

Managing Stall-Walking

First identify when the horse walks.

Common patterns include:

• Before feeding

• When companions leave

• After relocation

• During box rest

• When turnout is reduced

• During travel or competition

• When a mare or stallion is reproductively aroused

• During pain or gastrointestinal discomfort

Management should address the trigger.

For a horse on veterinary box rest, unrestricted turnout may not be an option. Alternatives can include safely increased social contact, multiple forage points, controlled hand-walking when prescribed, stable relocation beside a calm companion and a more structured daily routine.

Should You Use a Cribbing Collar, Muzzle or Anti-Weave Bars?

Mechanical devices may suppress the visible behaviour, but they do not necessarily remove the motivation.

The research is mixed.

An earlier experimental study found that a crib strap increased cortisol in crib-biting horses and concluded that physically preventing crib-biting or weaving may have negative welfare effects. (Cambridge University Press & Assessment)

A later randomised crossover study involving eight crib-biting horses found that two collars and a muzzle significantly reduced crib-biting without clear evidence of substantial distress during the short treatment periods. However, the authors still emphasised that underlying husbandry factors should be improved rather than relying solely on suppression. (Beva)

My Practical View

A mechanical device may be considered when:

• The horse is injuring their mouth

• A medical procedure requires temporary prevention

• There is an immediate property or safety risk

• The horse is damaging an essential structure

• Management improvements are being introduced simultaneously

It should not be the first and only response.

The device must:

• Fit correctly

• Allow normal eating and drinking

• Avoid skin injury

• Be checked frequently

• Be removed if breathing, swallowing or behaviour changes

• Never be tightened simply because the horse still finds a way to crib

Visible suppression is not the same as treatment.

Does Surgery Cure Crib-Biting?

Surgery has been used to alter the muscles and nerves involved in crib-biting.

In a retrospective study of 33 horses undergoing a modified Forssell’s myectomy, 61% had no reported recurrence, while 39% eventually resumed the behaviour. Outcomes appeared better when surgery occurred within six months of the behaviour beginning. (Acta Veterinaria Brno)

This was not a randomised trial, and surgery does not address the environmental or welfare factors associated with development of the behaviour.

Surgery should therefore be viewed as a specialist option for selected severe cases, not routine treatment for every crib-biting horse.

Do Anti-Anxiety Medications Help?

Medication is not the routine first-line treatment for an established equine stereotypy.

There is no standard medication proven to reliably cure crib-biting, weaving or stall-walking in ordinary clinical use.

Medication may occasionally be considered when:

• Severe anxiety is present

• A compulsive disorder is suspected

• The horse cannot be managed safely

• Medical causes have been investigated

• Environmental improvements have been maximised

• A veterinarian with equine behaviour experience is directing treatment

Sedation should not be used simply to make a horse appear settled.

The treatment target should be the horse’s welfare and ability to function, not merely producing a quieter stable video.

Can Equine Stereotypies Be Cured?

Established stereotypies are often managed rather than cured.

Management may:

• Reduce their frequency

• Reduce physical harm

• Improve eating and rest

• Reduce triggering situations

• Improve social welfare

• Lower associated health risks

Some young horses stop or substantially reduce a newly developed behaviour. Others continue throughout life despite excellent management.

Persistence does not mean management changes have failed. The nervous system may have converted the behaviour into a well-established habit even after the original cause has changed.

How Can Stereotypies Be Prevented?

Prevention is most effective before the behaviour becomes established.

Focus on young horses and major management transitions.

Use Social, Gradual Weaning

Where possible:

• Avoid abrupt total isolation

• Keep familiar companions nearby

• Use calm adult horses

• Maintain forage access

• Avoid changing housing, diet and social group simultaneously

• Provide paddock movement

Stable or barn weaning and continued post-weaning confinement were significant risk factors for abnormal behaviour in the four-year prospective study. (Beva)

Provide Forage for Much of the Day

Avoid repeated long fasting periods.

Use safe controlled-forage systems for horses requiring weight management rather than simply removing all forage for hours.

Minimise Unnecessary Concentrate

Feed concentrate only when forage alone cannot meet the horse’s nutritional needs.

Provide Daily Movement

Daily turnout, paddock access and safe voluntary movement should be treated as core husbandry rather than optional entertainment.

Maintain Social Relationships

Stable social groups and regular contact help horses develop and retain normal communication skills.

Introduce Confinement Gradually

Prepare young horses for short periods of stabling before asking them to tolerate prolonged confinement, travel, competition or rehabilitation.

Monitor Early Warning Signs

Early repetitive oral or locomotor behaviour should trigger a management review before the pattern becomes deeply established.

Common Mistakes Owners Make

Calling It Bad Behaviour

Punishment does not correct hunger, isolation, pain or frustration.

Assuming Other Horses Will Copy

There is little evidence for behavioural contagion. Isolating the affected horse may make the underlying social restriction worse.

Using a Collar Without Changing Anything Else

The horse may stop cribbing while remaining hungry, socially isolated or frustrated.

Treating Every Repetitive Movement as a Stereotypy

Pawing can be colic. Circling can be neurological. Headshaking can be painful. New behaviour requires diagnosis.

Relying on Toys Alone

A hanging ball cannot replace forage, turnout or another horse. It is enrichment, not a complete welfare program.

Assuming Ulcer Medication Will Cure Cribbing

Gastric disease deserves investigation when indicated, but an established stereotypy can continue after the stomach improves.

Ignoring Weight Loss or Recurrent Colic

Those are medical problems, not acceptable side effects of owning a cribber.

Frequently Asked Questions

Can horses catch cribbing from another horse?

There is little evidence that horses simply copy crib-biting from stablemates. Horses living together may develop similar behaviour because they share the same diet, confinement and social restrictions. (Beva)

Does cribbing cause colic?

Crib-biting and windsucking are associated with increased colic risk, including recurrent colic and epiploic foramen entrapment. The exact causal pathway is not fully understood, so cribbing should be treated as a risk marker rather than proof that colic will occur. (Beva)

Does cribbing mean my horse has gastric ulcers?

No. Young crib-biting horses have shown greater gastric inflammation and ulceration in research, but many ulcerated horses do not crib and many established cribbers will continue after gastric treatment. Gastroscopy is needed for diagnosis. (BVA Journals)

Should I put a cribbing collar on my horse?

Not as the only treatment. A collar may temporarily reduce the behaviour when there is a specific safety or medical reason, but forage, turnout, social contact and physical health should be reviewed first.

Will my horse ever stop weaving or cribbing?

Some horses improve substantially after management changes, particularly when the behaviour is identified early. Long-established stereotypies commonly persist, but their frequency and welfare impact can often be reduced.

Should I avoid buying a horse that cribs?

Crib-biting is not automatically a reason to reject a horse. Consider the horse’s colic history, dental health, body condition, management needs, stable-damage risk and whether your property can provide sufficient forage, turnout and social contact. Check whether your boarding facility has restrictions before purchase.

Final Thoughts

Crib-biting, windsucking, weaving and stall-walking are not simply irritating habits.

They are behaviours shaped by the horse’s early experiences, feeding system, social environment, confinement, physiology and individual susceptibility.

The most important correction is that stopping the visible movement is not the same as treating the horse. A collar, bar or muzzle may suppress what you can see while leaving the underlying motivation untouched.

Start with the basics:

• Rule out pain and disease

• Protect forage access

• Reduce unnecessary concentrate

• Increase free movement

• Improve meaningful social contact

• Make the environment safe

• Monitor weight, appetite, manure and colic

• Avoid punishment

Some horses will continue performing an established stereotypy even after their welfare improves. That does not mean the behaviour should be ignored, but it does mean the goal should be a healthier, safer and better-functioning horse rather than a perfectly still one.

ASK A VET™ can help you organise behaviour videos, feeding patterns, turnout records, body-weight changes and colic observations so that recurring stereotypies can be assessed in context. New behaviour, weight loss, recurrent colic, neurological signs or injury still requires direct veterinary examination.
