Colic Emergencies in Horses, Donkeys, and Mules
Recognize abdominal pain, understand why mild signs can be serious, and prepare for farm treatment or urgent hospital referral.
Do not delay care to finish this guide.
Call an equine veterinarian now for suspected colic. Severe pain, weakness, or collapse requires immediate emergency assistance; do not wait for rolling to occur.

The immediate priority is safe access to a veterinarian familiar with the species. The examination and stabilization plan come before trying to name the condition at home.
This guide explains possible causes and care decisions. It does not prescribe a treatment or establish that an animal or colony is safe to monitor without professional advice. Follow the plan for the actual situation and bring the information requested by the care team.
What Colic Means
Colic describes abdominal pain rather than one diagnosis. Gas accumulation, impacted feed, intestinal inflammation, obstruction, and displaced or twisted intestine can all produce similar outward behavior. Some problems respond to medical care, while others threaten the blood supply to the bowel and need surgery. An owner cannot reliably distinguish those categories by how loudly or dramatically an animal reacts.
This guide applies to domestic horses, donkeys, and mules. Knowing the individual animal matters: a quiet donkey that stops joining its companion may be showing a meaningful emergency sign.
Signs Owners May Notice
Look for repeated pawing, watching or biting at the flank, stretching, frequent lying down, rolling, sweating without an obvious reason, or refusing feed. Manure production may decrease, but passing manure does not rule out an obstruction because material already beyond the affected area can still leave the body. Some animals become unusually withdrawn rather than restless.
Donkeys often show less obvious pain than horses. Dullness, reduced appetite, isolation, or a change in ear position and interaction can deserve prompt attention. Describe those changes clearly rather than reporting only that the animal is not rolling. Mules also deserve assessment based on their own behavior and examination, not assumptions about toughness.
Why Prompt Contact Matters
Contact the veterinarian when colic is suspected, even if signs appear mild. Report violent or repeated rolling, persistent sweating, worsening abdominal enlargement, marked weakness, or inability to stand as emergencies. An animal that becomes quiet after sustained severe pain is not necessarily recovering. Exhaustion or shock can reduce its ability to show discomfort.
Explain how long signs have been present and whether they are changing. If the veterinarian asks for vital signs, provide only measurements you can safely obtain and interpret with their help. Do not risk a kick or delay assistance to complete a checklist.
Safe Actions While Help Is Arranged
Remove access to feed until the veterinarian gives a feeding plan, and ask specifically about water access. Keep the animal where observation and veterinary access are possible, with hazards removed. Stay out of the path of a distressed horse. A quiet companion nearby may reduce stress when it can be managed safely, but avoid crowded spaces or situations that put people between animals.
Gentle walking may be advised if the animal is comfortable and the handler can remain safe. Do not force continuous walking, exhaust the animal, or chase it to keep it upright. If it can lie quietly in a safe area, ask the veterinarian whether resting is appropriate. Walking does not untwist intestine and must not replace veterinary assessment.
Actions That Can Make Matters Worse
Do not pour oil, water, or other remedies into the mouth, administer an enema, or attempt to pass a stomach tube. Incorrect administration can cause aspiration or injury. Do not reach into the rectum to perform an examination. These are procedures requiring veterinary training, restraint decisions, and an understanding of the risks.
Give pain medication only according to current veterinary instructions for this episode. Tell the veterinarian about every drug already given, including the amount and time. Temporary relief is valuable but can mask worsening disease. Avoid repeated doses because pain returns, and do not assume a medication supplied for an earlier episode is automatically appropriate now.
Information That Helps the Veterinarian
Prepare a short timeline covering the last normal meal, drinking, manure, work, and behavior. Include recent feed changes, grain access, travel, deworming, dental care, previous colic or surgery, and medicines. Mention diarrhea, suspected toxin exposure, a new pasture, or several animals becoming ill. Those details help direct the examination without determining the diagnosis by themselves.
For donkeys, promptly report reduced intake even when pain looks mild. Ask about the additional consequences of not eating and the need for nutritional monitoring. Collect packaging or photographs of suspect feed if safe, but do not spend time searching the property while emergency care is being delayed. Keep someone available to answer calls and guide the veterinarian to the animal.
What Professional Assessment May Involve
The veterinarian evaluates pain, circulation, hydration, intestinal sounds, and the animal’s overall condition. Depending on findings, the examination may include ultrasound, blood tests, abdominal fluid sampling, a carefully performed rectal examination, or a stomach tube to assess and relieve stomach fluid accumulation. Not every animal needs every test, and some procedures are inappropriate until restraint or stabilization is arranged.
Repeated assessment is often important because colic changes over time. The veterinarian may recommend referral based on persistent pain, concerning circulation, imaging findings, or the need for monitoring unavailable at the farm. Referral does not mean surgery is inevitable; it means that further evaluation and treatment can be available without another transfer if deterioration occurs.
Preparing for Referral and Transport
Ask the veterinarian whether the animal is fit to travel and what stabilization is needed first. Contact the receiving hospital before leaving, confirm its entrance and acceptance, and organize a suitable trailer and experienced driver. Do not try to drag or force a collapsed animal into a trailer. Safe recovery and transport of a down equine require professional planning.
Bring identification, medication records, insurance information if applicable, and a reliable contact number. Prepare these decisions before a crisis whenever possible. During travel, follow the clinical team’s instructions about feed, observation, and companions; do not create a handling hazard by attempting examinations inside a moving trailer.
Treatment and Recovery
Treatment depends on the cause and severity. Veterinary care may include pain relief, fluids, carefully selected enteral treatment, hospital monitoring, or surgery. A bowel obstruction or loss of blood supply needs a different approach from uncomplicated gas discomfort. The response to initial treatment helps guide the next step but does not establish that the episode is resolved.
After improvement, obtain written instructions for feed reintroduction, medication, activity, and monitoring. Watch appetite, comfort, manure, drinking, and attitude rather than relying on one reassuring sign. Contact the team if pain returns or eating remains poor. Surgical patients have additional wound, exercise, and follow-up requirements; another animal’s recovery timetable is not a safe substitute for that individual plan.
Reducing Future Risk
Review water availability, forage quality, feeding consistency, dental care, and parasite control with the veterinarian. Introduce management changes gradually and prevent accidental grain access. Weather, travel, and a change of caretaker can disrupt drinking or feeding routines, so make written care instructions accessible. Prevention reduces some risks but cannot eliminate every cause of colic.
Keep emergency numbers, trailer arrangements, hospital directions, and a basic record of normal behavior ready. Ask what early signs are especially important for this animal and which medicines may be used only after a phone consultation. A prepared response helps owners recognize changes sooner and avoids losing valuable time deciding whom to call when abdominal pain begins.
Questions for the care team
Ask these once urgent care is underway; collecting answers should not delay the initial call.
- Which changes require immediate referral rather than continued farm monitoring?
- What should I do about feed, water, and walking while you travel here?
- Which signs are especially subtle in my donkey or mule?
- What is the recheck and feeding plan after this episode?
