Horse Down and Can’t Get Up: Emergency Steps Before the Vet Arrives

A horse may be recumbent because of severe pain, weakness, injury, neurologic disease, or metabolic problems. Common causes include colic, fractures or other trauma, severe lameness, and muscle injury such as exertional rhabdomyolysis ("tying up"). Horses can also go down from shock, blood loss, overheating, or exhaustion. In mares, difficult foaling and post-foaling complications are important emergency causes.

Neurologic disease is another major category. Conditions that affect the brain, spinal cord, or nerves can cause weakness, incoordination, or inability to rise. Examples include equine protozoal myeloencephalitis (EPM), viral encephalitis, severe head or neck trauma, and some toxic or infectious disorders. Metabolic problems such as hypocalcemia can also cause muscle tremors, weakness, and recumbency.

Sometimes the horse is technically able to move but is too painful, exhausted, or unstable to stand safely. A horse that has been down for a while can then develop secondary muscle and nerve damage, making it even harder to rise. That is one reason time matters so much in these cases.

Because the list of causes is broad, pet parents should avoid guessing. Your vet will use the history, physical exam, and the horse's mentation, pain level, and ability to move the limbs to narrow down the cause and decide whether treatment, referral, or humane euthanasia is the safest option.

A horse that is down and cannot get up is not a monitor-at-home situation. See your vet immediately. Horses are not built to stay recumbent for long periods, and complications can develop quickly. Even if the horse briefly tries to rise, repeated failed attempts, heavy sweating, distress, abnormal breathing, or obvious pain all raise the urgency further.

Call your vet at once if the horse is trapped against a wall, cast in the stall, showing colic signs, has had a fall, may have a fracture, is weak after transport or exercise, is a mare around foaling, or has neurologic signs such as stumbling, tremors, head tilt, or a wobbly gait before going down. Also treat it as an emergency if the horse is dull, has pale or dark gums, is bleeding, or seems unable to bear weight on one limb.

While waiting, focus on safety and observation. Keep the area quiet, note the time the horse went down, and watch breathing, sweating, attempts to rise, manure and urine output, and any signs of trauma. If the horse is thrashing violently, protect people first and call your vet back with an update.

The only time "monitoring" applies is after your vet has already examined the horse and given you a specific plan. Until then, recumbency in an adult horse should be treated as a red-level emergency.

Your vet will first assess safety, pain, circulation, breathing, and whether the horse can be helped to stand safely. The exam often includes heart rate, breathing rate, temperature, gum color, hydration, gut sounds, limb evaluation, and a neurologic check. Your vet will also ask about recent exercise, transport, trauma, colic signs, foaling, medications, and how long the horse has been down.

Initial treatment depends on the suspected cause. Your vet may give pain control, sedation, IV fluids, electrolytes, or emergency medications, and may pass a nasogastric tube if colic is suspected. If trauma or fracture is possible, they may stabilize the limb and avoid forcing movement. In some cases, short-term anesthesia or controlled assistance is needed to move the horse more safely.

Diagnostic testing may include bloodwork, lactate or muscle enzyme testing, ultrasound, radiographs, rectal exam, or referral for advanced imaging and intensive monitoring. If the horse is recumbent from a neurologic or metabolic problem, your vet may recommend hospitalization for repeated exams, fluid therapy, sling support, or treatment of the underlying disease.

If the horse has severe injuries, prolonged recumbency, or a poor chance of recovery with acceptable welfare, your vet may discuss humane euthanasia. That conversation is never easy, but it is part of thoughtful emergency care when suffering is high and recovery is unlikely.

Home care starts with calling your vet immediately and keeping everyone safe. Move other horses away, reduce noise, and keep children and bystanders back. If the horse is in a stall and safely reachable, remove buckets, hay nets, and sharp objects. If possible without putting yourself at risk, place deep bedding or other soft footing around pressure points.

Do not pull on the head, tail, or limbs to force the horse up. Do not drag the horse with equipment, and do not give sedatives, pain medications, or oral products unless your vet specifically instructs you to. If the horse is thrashing, stay clear of the legs and update your vet. If the horse is quiet and your vet advises it, you may help keep the head and neck in a natural position and protect the horse from getting cast tighter against a wall.

Useful information for your vet includes the exact time the horse went down, recent exercise or transport, any fall or collision, colic signs, foaling status, recent medications, manure and urine output, appetite, and whether the horse has tried to rise. Photos or short videos can help if they can be taken safely.

After your vet arrives, home nursing may include deep bedding, frequent repositioning, careful hydration and feeding plans, and close monitoring for pressure sores, swelling, or renewed weakness. The details depend completely on the cause, so follow your vet's instructions rather than a one-size-fits-all plan.
