Horse Colic: How to Read the Signs and
What to Do Beforethe Vet Arrives
Every horse owner remembers their first bad colic. You walk out to the barn and something's just off. He's not at the gate. He's standing in the corner, head low, pawing at the dirt — then he swings around and stares at his own belly. Your stomach drops, because somewhere deep down you already know.
Here's the truth that twenty-five years around sick horses will teach you: colic is the most common reason a horse needs an emergency vet, and one of the leading natural killers of horses — but most colics are not the bad kind, and the person standing in that stall is the biggest factor in how the night ends. You're almost always the first one there. Long before the vet's truck comes down the drive, it's your eyes, your hands, and your steady head buying your horse time. This guide shows you how to use all three.
The first hour, step by step
How do you prevent colic?🤠 A horseman's bottom line: Stay calm, take the heart rate, pull the feed, and call your vet early. Do those four things and you've already done your horse a world of good. This guide is education for owners — it does not replace your veterinarian. When in doubt, make the call. You'll never regret the colic call that turned out to be nothing.
The first hour is yours, and how you use it matters. Here's the order that works:
- Call the vet first — always. Even if it looks mild. Describe the signs, read off the vital signs, and let the vet decide how fast they need to come. Calling early is never the wrong call, and it's the cheapest call you'll ever make.
- Pull all feed. Hay and grain come away. Leave water unless your vet says otherwise.
- Write down the clock. When it started, the vital signs, the last manure you saw, the last time he ate and drank, and anything that changed lately — new hay, a skipped deworming, a sandy paddock, a cold snap. The vet will want all of it.
- Keep him calm and safe. Your nerves travel right down the lead rope, so slow your own breathing first. Put him where he can't hurt himself if he goes down.
- Hand-walk only to prevent rolling. If he's frantic and keeps trying to hurl himself down, walk him slow and easy, ten or fifteen minutes at a stretch, to settle him and stop a dangerous roll. If he'll stand or lie quietly without thrashing, let him rest — walking is a tool, not a cure.
- Get ready to haul. If there's any chance this becomes a referral or a surgery, hook the trailer up and have it ready before the vet even arrives. Minutes saved here have saved lives.
What you should NOT do
Good intentions hurt horses every year. Steer clear of these:
- Don't reach for Banamine or bute on your own. Pain meds can mask a surgical colic and rob your vet of the signs they need to make the right call. Give them only when, and how, your vet directs.
- Don't walk him into the ground. An exhausted horse is in worse shape, not better. Walk only to stop rolling.
- Don't let him eat, no matter how bright he looks once the pain eases. Wait for your vet's all-clear.
- Don't drench him with oil, salt, or home remedies. You can send it down the windpipe and into the lungs. Leave the tubing to the vet.
- Don't "wait until morning" on a horse with red-flag signs. Colic can go from mild to surgical in a few hours.
You can't promise a horse will never colic, but you can stack the deck hard in his favor. Almost all of it comes back to one idea: a horse's gut was built to trickle-feed forage and water all day long. The closer you keep him to that, the safer he is.
- Forage first, always. Plenty of good hay or pasture, fed little and often, keeps the gut moving the way nature intended.
- Water — and warm it in winter. Horses drink less when water is icy cold, and that's exactly when impaction colics spike. A few degrees of warmth keeps a horse drinking.
- Change feed slowly. Phase any new hay or grain in over about two weeks. Sudden changes are a classic trigger.
- Beat the sand. Feed off mats or in slow-feeders, never off bare dirt, and ask your vet about a periodic psyllium routine if you live in sandy country.
- Keep him moving. Turnout and regular exercise keep the gut working. The stalled-up, idle horse colics more.
- Mind the teeth and the worms. Yearly dental floats so he can chew his feed, and a parasite program built on fecal egg counts, not guesswork.
- Know his normal. His resting heart rate, his manure, his appetite, his gum color. You can't spot "off" until you know "normal."
Build your colic plan before it ever happens
The owners who come through a colic well are the ones who got ready on a calm day. Before you ever need it:
- Post your vet's number — and a backup clinic's — where anyone at the barn can find it.
- Keep the trailer maintained and ready to roll, and make sure your horse loads.
- Stock a simple first aid kit and learn to take vital signs until it's second nature. A hands-on equine first aid class is worth every penny.
- Sort out the money question ahead of time — insurance or an emergency fund — so it never slows you down.
❓ FAQ / Solution Section (all 9 — paste into the article's Solution Section / additional_info)
Is horse colic always an emergency? — Treat every colic as an emergency until your vet says otherwise. Many turn out to be mild gas or spasmodic colic that settles quickly — but the dangerous kinds look the same in the first hour, and minutes matter if it's a twist. Calling your vet early is never the wrong move.
What's the very first thing I should do if I think my horse is colicking? — Call your veterinarian, then take away all hay and grain and note the time and your horse's heart rate. Don't give any medication unless your vet directs you to. Those first few steps protect your horse and give the vet the information they need.
Should I walk a colicking horse? — Only to stop dangerous rolling. If your horse keeps trying to throw himself down, a slow, easy walk can settle him. But the old idea that you must walk a colicking horse for hours is a myth — if he'll stand or lie quietly without thrashing, let him rest. Never walk him to exhaustion.
Can I give my horse Banamine for colic? — Only if your veterinarian directs you to, at the dose they specify. Pain medication given too early can mask the signs of a surgical colic and delay a life-saving decision. Take the vital signs and call first.
How do I take my horse's heart rate? — Press a stethoscope behind the left elbow and count beats for 15 seconds, then multiply by four — or feel the artery along the lower jaw with two fingers. A normal resting adult horse is 28–44 beats per minute. A rate over 60 signals serious pain and a likely emergency.
Will my horse survive colic? — Most horses recover fully, especially when colic is caught early and treated promptly — the majority of cases are mild and resolve with simple veterinary care. Surgical colics are far more serious and time-sensitive, which is exactly why fast recognition and an early call make such a difference.
How much does colic treatment or surgery cost? — It varies widely. A farm call and treatment for a mild colic often runs a few hundred dollars; hospitalization with fluids can reach the low thousands; and colic surgery with aftercare commonly runs from several thousand into five figures. Catching colic early and carrying equine insurance or an emergency fund both help enormously.
Can cold weather or stress cause colic? — Yes. Cold weather is a classic trigger because horses drink less icy water, which leads to impaction colic — warming the water helps. Stress, sudden feed changes, sandy ground, dental problems, and parasites are other common causes. Steady forage, plenty of water, and a consistent routine are your best prevention.
How long does colic last? — A mild gas or spasmodic colic may ease within a few hours of treatment. But you should never just wait it out — because you can't tell a mild colic from a serious one by time alone, any colic that lasts more than a short while, or that worsens at any point, needs your veterinarian.
