If your horse is restless, keeps looking at its belly, or stays down, the first question is: is this colic, and how serious? This guide helps you recognize the signals, judge the urgency, and act. Diagnosis and treatment always belong with the vet — if in doubt, call right away.
What Colic Is
Colic isn't a disease in itself, but an umbrella term for abdominal pain. The causes vary widely: a blockage in the intestine, gas buildup, cramping, sand accumulation, or, in the most serious cases, a twisted gut. Some cases are mild and resolve on their own or with light treatment. Other forms are life-threatening within hours.
As an owner, you can't determine the cause in the moment — and you don't need to. Your job has three parts: recognize the signals, judge how serious it is, and call in the vet in time. The faster a serious form is recognized, the better the odds of a good outcome.
The Symptoms
A horse in abdominal pain shows it in fairly recognizable ways. Watch for behavior that deviates from what's normal for your horse:
- Repeatedly lying down and getting up again, or staying down for a long time
- Rolling, sometimes violently and with legs in the air
- Kicking or biting at its own belly, looking back at the flank
- Pawing the ground, pacing restlessly in the stall
- Refusing to eat when it normally would
- Little or no manure, or noticeably dry manure
- Sweating without having worked
- A visibly swollen belly
- Repeated yawning or curling of the upper lip
A single isolated sign doesn't necessarily mean anything — a horse will sometimes roll out of simple comfort. It's the combination that counts: restlessness plus not eating plus clear pain behavior is reason to be alert right away.
How Serious Is It: Judging the Urgency
The rule of thumb: the more intense the pain and the more signs at once, the greater the urgency. The breakdown below helps with the assessment but doesn't replace the vet's judgment.
| Picture | What you see | Action |
|---|---|---|
| Mild | Somewhat restless, looks back at the belly, eats hesitantly, stays standing | Call the vet to discuss, keep a close eye on the horse |
| Moderate | Repeatedly lies down and gets up, rolls calmly, won't eat, little manure | Have the vet come out, don't wait it out |
| Severe | Rolls violently, throws itself down, sweats, can't be calmed | Call emergency services immediately, possible transport to a clinic |
Two things always raise the urgency: pain that persists or increases despite rest, and pain so intense that the horse throws itself down and risks injuring itself. With the latter, there's no need to hesitate — call the emergency service.
Vital Signs: Your Baseline
To recognize "abnormal," you need to know what's normal. Measure these values on your own horse a few times at rest so you have a reference point. The ranges below are general; they can vary slightly per horse.
| Value | Normal at rest (adult horse) |
|---|---|
| Heart rate | roughly 28–44 beats per minute |
| Respiration | about 8–16 breaths per minute |
| Temperature | around 37.5–38.5°C |
| Mucous membranes (gums) | pink and moist |
| Capillary refill time | within about 2 seconds |
With colic, an elevated heart rate is one of the most useful warning signs: a pulse that stays well above 44–48 at rest often points to pain. Gut sounds tell you something too — a belly that's completely silent, or one that gurgles abnormally loudly, both belong in your report to the vet. Pale, dry, or dark red mucous membranes and a slow refill time (press briefly on the gum and see how quickly the color returns) are also important to pass on. Report the values you measured when you call — they help gauge how quickly someone needs to come.
What to Do Right Away
Your role is to keep the horse safe and calm and not make the situation worse — not to treat it yourself.
- Call the vet (or the emergency service right away if you suspect a serious form). Describe the behavior, how long it's been going on, and the vital signs. Ask what to do until they arrive.
- Take away feed. Don't let a horse with abdominal pain keep eating. Water can usually stay available, unless the vet says otherwise.
- Let the horse walk calmly if it wants to, but don't force anything and don't force movement if it's exhausted. The old idea that you have to walk a colicking horse for hours to stop it from rolling is outdated — discuss this with the vet.
- Make the surroundings safe: a thickly bedded stall or soft footing, sharp edges removed, other horses kept away so the horse doesn't hurt itself while rolling.
- Don't give painkillers or any other medication on your own initiative. These mask pain signals and make assessment harder. Only on the vet's instruction.
- Note the time the symptoms started and how they change. That's valuable information on arrival.
What Reduces the Risk of Colic
Colic can never be fully prevented, but a number of habits lower the risk. This is especially relevant for competition riders: transport, a changed routine, and stress on a show day are known triggers.
- Provide unlimited or generously spread-out forage; long periods without hay increase the risk.
- Feed concentrates in small portions and change the ration gradually, over several days.
- Always provide clean water; drinking too little is a common factor, especially in winter and during transport.
- Keep a consistent deworming policy based on fecal egg counts and have the teeth checked yearly.
- Limit ingestion of sand from bare pasture or a sandy surface.
- Build back up gently after transport or a competition and keep an eye on the horse for the first few hours.
In Short
Treat restlessness combined with not eating and pain behavior as colic until proven otherwise. Learn your own horse's normal vital signs so deviations stand out, and report them when you call. Take away feed, keep the surroundings safe, and don't give anything on your own initiative. With severe, persistent pain, call the emergency service right away; if in doubt, call anyway — better one time too early than one time too late. For diagnosis, exact values, and treatment, the vet is the only correct source.
