What Every Equestrian Should Know About Ataxia in Horses

Ataxia in horses is a loss of coordination caused by a problem in the nervous system rather than in the limb itself. That distinction matters enormously. It changes how the horse is investigated, how it is treated, and above all how safe it is to handle and ride. When a horse starts stumbling, dragging its toes, swaying while standing or crossing its hind legs on a turn, ataxia belongs high on your list of concerns and lameness belongs lower down it.

Ataxia is not common, but it is always serious, and a proportion of cases are genuinely dangerous to be around. The sooner it is recognised and investigated properly, the better the outcome tends to be.

This guide covers what ataxia actually is, the three types vets distinguish between, how the standard grading scale works, the full list of causes with a British and South African slant, and what happens at diagnosis. It is written for horse owners and yard staff, not for vets, but it does not water the clinical detail down.

What Is Ataxia in Horses?

Ataxia is a clinical sign, not a diagnosis. It tells you that something is disrupting the nervous system, whether that is the brain, the spinal cord or the peripheral nerves, but it tells you nothing about what that something is. Wobbler syndrome, a virus, a fall, a vitamin deficiency and a mouldy bale can all produce a horse that moves the same way. The underlying cause has to be identified before any meaningful treatment can start.

Normal, coordinated movement depends heavily on proprioception, which is the horse’s ability to sense where its limbs are without looking at them. Nerves running from the limbs to the spinal cord and brain report joint angle, muscle tension and foot position continuously, and the brain uses that stream of information to place the next stride. When the pathway carrying those signals is damaged or compressed, the information arrives late, distorted or not at all. The result is a gait that looks unsteady, exaggerated or badly timed.

This is why an ataxic horse often looks worse when you make the task harder. Walking in a straight line on level ground is something a horse can partly manage on momentum and habit. Turning tightly, walking on a slope, backing up with the head raised, or having the tail pulled sideways all force the horse to react and rebalance, and that is where a deficit shows.

The Three Types of Ataxia in Horses

Vets separate ataxia into three types according to which part of the nervous system has failed. Knowing which type you are looking at narrows the list of causes dramatically, which is why the neurological examination is built around telling them apart.

• General proprioceptive, or spinal, ataxia. Damage to the spinal cord or the sensory pathways running through it. This is by far the most common form in horses, and it is what wobbler syndrome, spinal trauma and most infectious spinal disease produce. The horse does not know where its feet are, so it places them badly.
• Vestibular ataxia. Damage to the balance apparatus of the inner ear or its connections in the brainstem. The horse has lost its sense of which way is up, so it leans, tilts its head, circles or falls consistently towards one side.
• Cerebellar ataxia. Damage to the cerebellum, which fine tunes movement rather than initiating it. The horse knows where its limbs are and has normal strength, but cannot regulate the size and force of a movement. The classic picture is an exaggerated, high stepping, jerky action, often with a head tremor that gets worse when the horse concentrates on something.

The practical difference for an owner is weakness. Spinal ataxia usually comes with weakness, and the horse may buckle or nearly go down when circled tightly. Cerebellar ataxia does not cause weakness, and the horse is more likely to look clumsy and overdone than unsteady. Vestibular disease tends to be asymmetric in an obvious way, with a head tilt that is visible from the front.

How to Recognise Ataxia in Horses

Common Signs to Watch For

Ataxia most often shows in the hind limbs first, although all four can be involved. In the majority of spinal cases the hind limbs are roughly one grade worse than the forelimbs. Signs worth taking seriously include:

• Stumbling or tripping noticeably more than the horse used to
• Dragging the toes, which usually shows up as square scuffing on the front of the hoof wall or the shoe
• Swinging a limb too far outwards, or placing it underneath the body
• Crossing the limbs when turning
• Standing with an unusually wide base, as though bracing
• Swaying through the trunk or neck while standing still
• Treading on itself, particularly overreaching onto a front heel
• Pivoting on the spot when turned, staying rooted while the legs catch up, instead of stepping across cleanly
• Being slow to correct itself after a trip, so a small stumble turns into a near fall

The single most useful thing to watch for is inconsistency. As Horse & Hound’s veterinary explainer puts it, with ataxia the gait changes all the time. A leg might swing out to the side on one stride and under the body on the next, a joint might overflex, a foot might scuff. Lameness repeats itself. Ataxia does not.

In some horses the signs are clearly asymmetric, with one side worse than the other. That pattern points towards an inflammatory or infectious cause rather than a symmetrical compressive one, and it is also the pattern most likely to be mistaken for lameness at first glance.

How Ataxia Differs from Lameness

A lame horse has a consistent, repeatable change in gait driven by pain or a mechanical restriction in one limb. Trot it up ten times and you see the same thing ten times. An ataxic horse produces uncoordinated movement that varies stride to stride, can shift between limbs, and is accompanied by a loss of balance that lameness does not cause. A lame horse knows exactly where its foot is and does not want to put weight on it. An ataxic horse does not reliably know where its foot is at all.

Vets use a specific set of manipulations to separate the two: watching the horse on a slope and on a firm surface, walking it in tight circles in both directions, pulling the tail sideways while it walks to test how easily it can be displaced, backing it up with the head raised, and placing a limb in an odd position to see how long the horse takes to correct it. A neurologically normal horse resents having its tail pulled and resists it. An ataxic horse gets dragged sideways.

It is worth knowing that severe ataxia and severe lameness can look similar to an untrained eye, and that the two can coexist. Older horses with arthritic change in the neck can present with a forelimb lameness caused by nerve root compression, with the ataxia only becoming obvious once someone looks for it.

Conditions That Can Be Mistaken for Ataxia

Not every horse that moves oddly is ataxic. Several conditions produce an abnormal gait through an entirely different mechanism, and confusing them wastes time and money:

• Foot pain. A horse with a severe foot abscess can genuinely look ataxic, which is one reason a routine physical examination comes before the neurological one.
• Shivers. A neuromuscular condition producing hindlimb hyperflexion and trembling, typically when backing up or picking up a hind foot, but a normal gait going forwards. See our entry on equine shivers.
• Stringhalt. An exaggerated, involuntary snatching up of one or both hind limbs, consistent and repeatable rather than variable.
• Fibrotic myopathy and other mechanical gait faults. A restriction in the muscle produces a characteristic slapping down of the foot that never varies.
• Weakness without ataxia. Conditions such as botulism and transport tetany produce profound weakness and trembling but not true incoordination, and tetanus produces rigidity that is unmistakable once you have seen it.

Grading Ataxia in Horses: The 0 to 5 Scale

Vets grade ataxia on a standard scale so that severity can be recorded objectively and progress tracked over weeks or months. The grade is also the single biggest factor in deciding whether a horse is safe to ride and whether surgery is worth attempting. The grades below follow the scale Dr Philip Ivens MRCVS sets out in Horse & Hound’s veterinary explainer on ataxia, written up by Andrea Oakes. The scale runs from 0 to 5:

0. Grade 0. Normal strength and coordination. No deficit under any test.
1. Grade 1. Walks normally in a straight line, but shows a slight deficit on tight circles or with the head extended. May sway when the tail is pulled.
2. Grade 2. Ataxia present at all times, though mild, along with a mild increase in muscle tone or weakness in all four limbs. Clearly worse during the manipulations described above.
3. Grade 3. A more marked increase in stiffness and obvious ataxia, with a tendency to buckle and fall when circled vigorously, backed up or swayed.
4. Grade 4. The horse spontaneously trips, stumbles and falls, without needing to be provoked into it.
5. Grade 5. The horse is recumbent and unable to stand.

Two practical points follow from this. First, a grade 1 horse can look completely normal in the school and still be neurologically abnormal, which is exactly why vets go looking for deficits rather than waiting for them to appear. Second, the jump from grade 3 to grade 4 is the point at which the horse becomes a serious danger to itself and to anyone near it, because it no longer needs a provocation to fall over.

Is Ataxia in Horses an Emergency?

Yes. Treat suspected ataxia as an emergency and call your vet the same day. There are three reasons.

• The horse is a fall risk. Even mild incoordination can become a stumble and a fall without warning, and an ataxic horse that goes down in a stable or a lorry can injure itself badly.
• Some causes are progressive and time sensitive. Compressive and inflammatory conditions generally respond better the earlier they are addressed.
• Some causes are contagious. If more than one horse on a yard develops neurological signs, you are potentially dealing with an outbreak, and every hour before biosecurity goes in makes it worse.

Do not ride a horse with suspected ataxia until a vet has assessed it. That is not an overcautious position. A horse that cannot reliably tell where its own feet are cannot be relied upon to catch itself, and the rider is the one who comes off worst.

Causes of Ataxia in Horses

Wobbler Syndrome, or Cervical Vertebral Stenotic Myelopathy

Compression of the spinal cord by the vertebrae of the neck is the most common non-infectious cause of ataxia in horses. It goes by several names: cervical vertebral stenotic myelopathy, cervical vertebral malformation, cervical spondylomyelopathy, or simply wobbler syndrome. We cover it in depth separately, and there is a reference entry on equine wobbler syndrome as well.

Two distinct populations are affected. Young horses, most of them under three years old and often well grown and fast developing, develop it through abnormal development of the cervical vertebrae. They present with symmetric ataxia, weakness and stiffness in all four limbs, hind limbs usually a grade worse than front, and no cranial nerve signs. Older horses more often develop it through arthritic change in the facet joints of the neck. They frequently show neck pain on palpation, may present initially for a forelimb lameness, and can have focal muscle wastage, focal sweating or palpable bony change along the neck.

Diagnosis starts with standing cervical radiographs and measurement of the vertebral sagittal ratios to assess how much room the spinal canal actually has. Radiographs alone identify a suspicious site but do not prove compression, so a myelogram is needed to confirm where the cord is being compressed and is essential if surgery is being considered.

Equine Herpesvirus Myeloencephalopathy (EHM)

Certain strains of equine herpesvirus attack the blood vessels supplying the spinal cord, producing the neurological form of the disease known as EHM. For British and South African yards this is the cause that should worry you most, because it is the one that spreads.

EHM typically appears suddenly, often following a fever, and the classic picture is hind limb weakness and incoordination that is worse behind than in front, reduced tail tone, and difficulty urinating or obvious dribbling. A wobbly horse with a bladder problem is EHM until proven otherwise. Because the virus moves between horses in shared airspace and on shared equipment, any yard with more than one neurologically affected horse should stop all movement on and off the premises and call the vet immediately rather than waiting to see what happens overnight.

Equine Degenerative Myeloencephalopathy (EDM) and Neuroaxonal Dystrophy

Equine degenerative myeloencephalopathy, also called equine neuroaxonal dystrophy or eNAD, is a progressive disorder involving diffuse degeneration of axons, myelin and neurons in the spinal cord and, to a lesser extent, the brainstem. The MSD Veterinary Manual records it in many breeds across North America, Australia and England, so it is a genuine British differential rather than an import.

The cause is not fully understood, but vitamin E deficiency and genetic factors are both thought to be involved. Signs usually appear during the first year of life and consist of symmetric ataxia and weakness in all four limbs, with the hind limbs often worse. They may then stabilise or progress slowly. Unlike EPM, EDM does not cause cranial nerve signs or muscle wastage.

There is no definitive test in the living horse. Diagnosis rests on the clinical picture plus exclusion of everything else, and one of the more useful features is that myelography and cerebrospinal fluid analysis both come back normal, which helps separate EDM from a compressive lesion. Low serum alpha-tocopherol supports the diagnosis, interpreted against the reporting laboratory’s own reference range.

Be careful about what vitamin E can and cannot do here. Ensuring mares and youngstock up to two years old have access to lush green pasture is a genuine preventive measure, and supplementing pregnant mares and newborn foals is preventive in affected families. Once neurological signs have developed, however, supplementation can prevent further worsening but does not reverse deficits that are already present. Anyone promising you a recovery from a bucket is overselling it.

Equine Protozoal Myeloencephalitis (EPM)

Start with the geography, because most of the material written about EPM online is American and does not say this clearly. According to the MSD Veterinary Manual, EPM is a common neurological disease of horses in the Americas, reported across most of the contiguous United States, southern Canada, Mexico and several Central and South American countries. Outside those regions it occurs only sporadically, in horses that have previously spent time in the Americas.

For a UK or South African owner, that means EPM is a serious consideration for an imported horse and a remote one for a horse that has never left the country. The reason is the parasite’s life cycle: the definitive host for Sarcocystis neurona is the North American opossum, and horses are infected by eating feed or water contaminated with sporocysts shed in its droppings. No opossum, no local transmission. A minority of cases are caused by the related Neospora hughesi, whose natural hosts have not been identified.

Where it does occur, EPM is notorious for variable and asymmetric signs, because the parasite can infect any part of the central nervous system. The typical presentation is asymmetric ataxia and limb weakness with regional muscle wastage, sometimes with cranial nerve involvement such as facial paralysis, head tilt or difficulty swallowing. A useful discriminator is that affected horses are not usually painful or febrile.

Diagnosis is genuinely difficult. It requires neurological signs consistent with EPM, exclusion of the other causes on this page, and demonstration of antibody production within the central nervous system. Antibodies can appear in the cerebrospinal fluid of clinically normal horses, either through blood contamination during sampling or by crossing an intact blood brain barrier, so a positive result on its own proves very little.

Three treatments are FDA approved, with apparently similar efficacy. The doses below are the ones printed on those products’ own labels and in the veterinary consensus statement, and they are given so you can follow what your vet is weighing up, not so you can medicate a horse. All three are prescription-only medicines and the protocol is a veterinary decision.

• Ponazuril paste, a loading dose of 15 mg/kg by mouth on the first day only, followed by 5 mg/kg by mouth every 24 hours for 27 further days – the dosage printed on the Marquis (ponazuril) product label. A flat 5 mg/kg every day for 28 days is the regimen the licensing trial ran, not the one on the label: the label adds the three-fold first-day loading dose because that is what brings blood and spinal fluid levels up to steady state within a day or two
• Diclazuril pellets, 1 mg/kg by mouth every 24 hours for 28 days – the dose on the Protazil (diclazuril) product label
• Sulfadiazine with pyrimethamine, 20 mg/kg of sulfadiazine and 1 mg/kg of pyrimethamine by mouth every 24 hours – the regimen set out in the ACVIM consensus statement on EPM (Reed et al., Journal of Veterinary Internal Medicine 2016;30:491-502), which describes it as running for up to six months rather than to a fixed stopping point

Twenty-eight days is the labelled course for the two antiprotozoals, but the same consensus statement notes that most horses with EPM are in fact treated for longer, generally six to eight weeks or more for as long as they are still improving, and that when to stop is judged on neurological improvement rather than on repeat antibody testing. On the efficacy: in the Marquis licensing work 28 of 47 horses (60%) treated at 5 mg/kg for 28 days improved by at least one neurological grade, and in the Protazil work 28 of 42 horses (67%) at 1 mg/kg were counted successes by the clinical investigators, falling to 10 of 24 (42%) on masked videotape review. Fewer horses than that recover completely, and relapses can occur up to two years after treatment stops. There is no vaccine. Treat any source still recommending nitazoxanide under the brand name Navigator as out of date, since it is no longer among the approved options.

Trauma

A fall, a collision, a pull back while tied, or a strike to the poll or neck can cause immediate neurological deficits. Trauma is the classic cause of ataxia that appears from nothing in a horse that was sound an hour earlier, which distinguishes it from the gradual onset of wobbler syndrome or EDM. Severity depends entirely on where the injury sits and how much damage was done, and a horse that has fallen over backwards deserves a neurological assessment even if it gets up and walks off.

Cerebellar Abiotrophy

Cerebellar abiotrophy is a genetic condition in which cerebellar cells develop normally and then degenerate, most familiar in Arabian foals. It produces the cerebellar picture described earlier rather than spinal ataxia: an exaggerated, high stepping action, a head tremor that worsens with concentration, poor judgement of distance, and a startle response that is wildly out of proportion. Affected foals typically appear normal at birth with signs emerging over the following weeks to months. It is worth knowing about because the gait is so distinctive that recognising it early saves a great deal of investigation.

Congenital Abnormalities

Some horses are born with structural abnormalities of the vertebrae or spinal cord. The best known is occipito-atlanto-axial malformation, or OAAM, in which the first and second cervical vertebrae and the base of the skull form abnormally, with fusion between the atlas and the occiput and underdevelopment of the atlas and the dens. It occurs across breeds but is familial in Arabians.

Affected horses may be ataxic from birth or develop signs later. An abnormal head and neck carriage is common, and in some cases an audible click can be heard when the head is moved. Radiographs confirm it.

Vestibular Disease

Disease affecting the inner ear or its brainstem connections impairs the vestibular system, which governs balance and spatial orientation. Affected horses show a head tilt, lean or fall consistently to one side, circle, and may have abnormal eye movements. Temporohyoid osteoarthropathy, in which the joint between the hyoid apparatus and the skull becomes arthritic, is a recognised cause and can also produce facial nerve paralysis. The presentation is different enough from spinal ataxia that it usually declares itself, but the underlying loss of coordination is the same problem seen from a different angle.

Toxins and Poisonous Plants

A long list of toxins can produce ataxia, and the list is strongly regional. Horse & Hound’s veterinary explainer notes that the most common toxic cause in the UK is severe nettle rash, which is worth remembering the next time a horse comes in from a field with overgrown headlands moving strangely. Heavy metals such as lead and arsenic are also implicated, as are ionophore antibiotics such as monensin when horses gain access to cattle or poultry feed. Ionophore poisoning is a genuine yard risk wherever livestock feeds are stored alongside horse feeds, and it is frequently fatal.

Mouldy feed is the other significant category. Equine leukoencephalomalacia, caused by fumonisin toxins in mould affected maize, destroys white matter in the brain and is a recognised cause of neurological disease in South Africa and other maize growing regions.

Ragwort deserves a specific mention because owners often expect it to cause neurological signs directly. It does not. Ragwort destroys the liver, and the neurological signs that follow, including aimless walking, head pressing and apparent incoordination, are the result of liver failure rather than direct damage to the nervous system. The distinction matters because the treatment and the prognosis are entirely different. If you are dealing with ragwort on your land, our guide to removing ragwort safely covers the practical side.

Sensible precautions are unglamorous but effective: store horse feed separately from livestock feed, inspect hay and haylage for mould before feeding, walk pastures regularly for poisonous plants, and take overgrown nettles more seriously than most people do.

Vitamin E Deficiency and Motor Neuron Disease

Beyond its role in EDM, prolonged vitamin E deficiency causes problems in horses of any age. Fresh green grass is the main natural source, so horses kept on dry lots, fed almost entirely on hay, or with poor fat absorption are the ones at risk. Blood testing identifies deficiency and guides supplementation.

The related condition to know about is equine motor neuron disease, which follows prolonged vitamin E deficiency in adult horses. It is worth distinguishing carefully, because affected horses are weak and trembling and stand with all four feet gathered underneath them, but they are not truly ataxic. They know where their feet are; they simply cannot hold themselves up.

Other Infectious Causes and Space Occupying Lesions

Several other infections reach the nervous system. West Nile virus and the equine encephalomyelitides are important in the regions where they circulate, and Lyme disease is occasionally implicated in neurological signs. Rabies can present as ataxia and is a genuine differential in South Africa and other countries where it is endemic. The UK is free of terrestrial rabies, so it is not a routine British concern, but it remains a reason to limit unnecessary handling of an undiagnosed neurological horse anywhere the disease exists.

Finally, anything that takes up space near the spinal cord can compress it. Synovial cysts, vertebral fractures and tumours including melanoma, lymphoma and plasma cell myeloma all appear in the literature as causes of ataxia, and they tend to produce signs that progress steadily and do not respond to treatment aimed at anything else.

How Vets Diagnose Ataxia in Horses

Diagnosis has two aims: confirm that the horse really is ataxic, and work out where in the nervous system the problem sits. Only then does the list of possible causes become short enough to test against.

It begins with history and signalment, because age and breed narrow things considerably. A two year old Thoroughbred and a twenty year old cob with the same grade of ataxia have very different likely diagnoses. Your vet will want to know how quickly the signs came on, whether the horse has fallen or been transported recently, whether it has travelled abroad, what it is fed, what is growing in its field, and whether any other horse on the yard is affected.

A general physical examination comes next, covering heart rate, respiratory rate and temperature, both to find other abnormalities and to rule out the things that mimic neurological disease. A fever points towards an infectious cause. A foot abscess explains a lot for very little money.

The neurological examination itself assesses cranial nerves, then watches the horse move: on a firm level surface, on a slope, in tight circles both ways, backing up with the head raised, and with the tail pulled to each side. The horse may be asked to walk over a kerb or with its head elevated, and limbs may be placed in abnormal positions to time the correction. From this the vet grades the ataxia and localises the lesion.

Further diagnostics follow the suspicion rather than being applied as a fishing expedition:

• Blood work for infection, inflammation, muscle enzymes, liver function and vitamin E status
• Cervical radiographs to assess the vertebrae and calculate sagittal ratios
• Myelography to confirm the site of spinal cord compression, which is essential before surgery
• Cerebrospinal fluid analysis for inflammatory and infectious disease, and for intrathecal antibody testing
• Advanced imaging such as CT, and MRI where the anatomy and the horse’s size allow it
• Specific infectious disease testing, including PCR on nasal swabs and blood where EHM is suspected
• Endoscopy of the guttural pouches where temporohyoid disease is a possibility

There is no single test for ataxia, and there is no shortcut. The goal is always to name the underlying disease.

Treatment and Supportive Care

Treatment depends entirely on the diagnosis, which is the whole reason for the diagnostic effort. Compressive disease may be managed medically with anti inflammatories and, in young horses, a controlled growth programme using a restricted plane of nutrition with balanced trace minerals, or surgically by stabilising the affected vertebrae. Arthritic older horses may benefit from ultrasound guided steroid injection into the affected facet joints. Infectious causes need the specific drug for the organism involved. Deficiency states need correcting and then time.

Alongside whatever specific treatment is chosen, supportive care matters and is often what the owner actually ends up doing:

• Deep, level bedding with banked sides, and removal of anything the horse could fall onto
• Hand feeding and hand watering where the horse cannot safely lower or raise its head
• Manual removal of faeces where the horse cannot pass them normally
• Urinary catheterisation where bladder function is affected, which is common in EHM
• Turning recumbent horses every three to four hours, or supporting them in a sling, to prevent pressure sores and muscle damage
• Anti inflammatory medication to reduce swelling around compressed or inflamed nervous tissue

Recovery from neurological injury is slow. Nervous tissue repairs over months rather than weeks, and improvement often continues for six months or more after the cause has been dealt with. Judging the final outcome too early is a common mistake in both directions.

Safety Around an Ataxic Horse

An ataxic horse is not being difficult and cannot be schooled out of it. Handle it accordingly.

• Keep the horse on level, non slip footing. Avoid slopes, steps, ramps and wet concrete.
• Give it room. Never stand where you would be crushed or knocked over if the horse swayed or fell towards you.
• Avoid tight spaces, and avoid backing the horse up in a confined area, since backing is one of the manoeuvres most likely to make it fall.
• Use a long lead rope so you are not directly beside the shoulder, and do not tie the horse solidly.
• Think hard before transporting. Travel is one of the highest risk activities for an ataxic horse. Discuss it with your vet first.
• Limit the number of people handling the horse until a diagnosis is confirmed, both for the infectious risk and so that the people who do handle it know what they are dealing with.

Call your vet as an emergency rather than waiting if the signs appeared suddenly, are getting worse, or come with a fever, urinary dribbling, reduced tail tone, facial changes, or if a second horse on the yard becomes affected.

Ataxia and the Pre-Purchase Vetting

Neurological assessment is part of a thorough pre-purchase vetting, and it is one of the areas where buyers most often do not realise what they are or are not getting. A vet examining a horse for purchase will typically watch it walk and trot in hand, turn in tight circles and back up, which will pick up moderate ataxia but can miss a grade 1 horse on a good day.

Two practical points for buyers. First, mild ataxia is a legitimate reason to walk away from a horse regardless of how well it jumps, because it affects soundness in the true sense and it can progress. Second, if a horse trips repeatedly during a viewing, do not accept “he is just lazy behind” or “he always does that on hard ground” as an explanation. Ask for the horse to be turned tightly both ways and backed up, and if you are not satisfied, have the vetting done properly and say specifically that you want the neurological assessment covered.

Prognosis for Ataxia in Horses

Outcome depends on three things: the underlying cause, the grade of ataxia at the point treatment starts, and how quickly it started. Lower grades and earlier intervention consistently do better.

Broadly, trauma and inflammatory conditions caught early can improve substantially, sometimes back to full work. EPM improves in roughly 60% of treated horses, though complete recovery is uncommon and relapse is possible for up to two years. Compressive disease in young horses can respond well to a controlled growth programme or to surgery, but neither is a guarantee. EDM, congenital malformations and cerebellar abiotrophy carry a guarded to poor outlook, because the damage is degenerative or structural rather than something that can be reversed.

The harder conversation is about residual deficits. A horse may recover enough to live comfortably in a field and still never be safe to ride again, and returning a horse with persistent ataxia to ridden work puts a rider on an animal that may fall. That is a decision to take with your vet, honestly, on the basis of the grade rather than on hope.

Ataxia is not a wait and see problem. If your horse is moving as though it does not quite know where its feet are, get it looked at. The British Horse Society publishes general health and welfare guidance, but nothing on a website replaces a vet with hands on the horse.
