When a horse paws at the ground, keeps turning to look at or bite its flank, and cannot seem to settle, most experienced owners feel their stomach drop, and for good reason. That cluster of behaviors is the classic picture of colic - abdominal pain - and colic is the single most common emergency killer of horses. It ranges from a mild gas ache that passes on its own to a twisted gut that needs surgery within hours. The trouble is that you often cannot tell which is which from the outside early on, so the safe rule is simple: treat every colic as urgent, and call the vet.

This guide is about the next hour: how to read the severity from your horse's vitals, what to do while help is on the way, and the two or three mistakes that make things worse.

Most Likely Causes

  • Gas or spasmodic colic: the most common and usually the mildest, from gas building in the gut. Often resolves with basic treatment.
  • Impaction: firm, dry manure blocking the gut, common with a sudden feed or hay change, poor water intake, or cold weather when horses drink less.
  • Sand colic: from grazing on sandy ground and taking in sand that irritates and blocks the gut.
  • Displacement or torsion: the gut moves out of position or twists. This causes severe, unrelenting pain and is a surgical emergency.
  • Other causes: parasites, gastric ulcers, and enteroliths (intestinal stones) can all trigger colic signs.

The signs tend to escalate in a recognizable order: pawing, then looking at or biting the flank, then kicking at the belly, then repeatedly lying down and getting up, then rolling and sweating. The further along that ladder a horse is, the more urgent it is.

Check These First

Vitals turn a scary situation into information the vet can act on. If you can do it safely, gather these:

🔍 Check the Vitals

  • Heart rate: normal is about 28-44 beats per minute. Over 60 signals serious pain or shock. Feel under the jaw or behind the left elbow.
  • Gut sounds: put your ear to the flank in all four quadrants (upper and lower, both sides). Some gurgling is good; a completely silent gut is a bad sign.
  • Gum color and refill: gums should be pink and moist, with color returning under 2 seconds after you press. Dark, purple, brick-red, or slow-refilling gums mean shock.
  • Manure: when did the horse last pass manure, and how much? A gut that has gone quiet often stops producing.
  • Temperature: take it if you can, and note it for the vet.
  • Behavior: is the horse trying to throw itself down and roll violently, or resting quietly? Violent rolling is a red flag.

Call the vet immediately for any colic - and treat it as critical if you see: Violent, repeated rolling · A heart rate over 60 · No gut sounds at all · Dark or purple gums with slow refill · Heavy sweating and unrelenting pain · No manure passed · A distended belly · A horse going down and unable to rise. Colic can progress to surgical in a matter of hours.

What to Do Tonight

  • Call the vet first. Do this before anything else and describe the signs and vitals. Early veterinary care is the biggest factor in survival.
  • Remove all food. Take away hay and feed. Do not let a colicking horse eat, because it can worsen an impaction or a displacement.
  • Leave water available. Do not withhold water unless your vet tells you to.
  • Manage rolling with walking. If the horse is trying to roll violently, hand-walk it gently to reduce the risk of injury and a twist. Do not exhaust it with hours of forced walking. If it will stand quietly, let it rest.
  • Do not give banamine or bute without the vet's go-ahead. Pain medication masks the signs the vet needs to judge severity.
  • Write down the timeline: when signs started, the last manure, the last meal, and water intake. Keep yourself and the horse safe from injury while you wait.

A clear history helps enormously when the vet arrives, and repeat colics often have patterns worth tracking. VetGPT's health tools let you log vitals, manure output, and feed or water changes over time and get an AI read on how urgent a set of signs looks, so you can hand the vet a precise picture instead of a rushed guess.

Common Questions

Is pawing always colic in a horse?

Not always, but pawing plus looking at or biting the flank, restlessness, repeatedly lying down and getting up, or rolling is the classic colic picture. Because colic can go from mild to surgical within hours, any horse showing this cluster should be assessed as a possible colic and the vet called.

How do I check if my horse's colic is serious?

Check three vitals. Heart rate should be 28-44 bpm; over 60 signals serious pain or shock. Gut sounds should be present in all four quadrants; silence is bad. Gums should be pink and moist with refill under 2 seconds; dark or slow-refilling gums mean shock. Any of these, or violent rolling and no manure, means a serious colic.

Should I walk a colicking horse?

Hand-walking helps if the horse is trying to roll violently, since it reduces injury and twist risk. But it does not cure colic and you should not exhaust the horse. If it will stand or rest quietly without rolling, let it, and wait for the vet.

Can I give banamine or bute for colic?

Not without talking to your vet first. These drugs mask the pain the vet needs to gauge severity and can hide a surgical case until it is too late. Call the vet, describe the signs, and follow their instructions on medication.
