What colic really means for your horse

Colic is not a single disease. It is a catch-all term for abdominal pain, and the causes range from a mild gas build-up to a twisted gut that can become life-threatening within hours. Because horses cannot vomit, anything that irritates or blocks the digestive tract tends to worsen quickly. The key is to know what is normal for your horse, so you spot the subtle changes early. Most cases are manageable, but the difference between a straightforward episode and a surgical emergency often comes down to how fast you act.

Early signs that deserve your attention

Mild colic can look like grumpiness or a horse that is simply “not quite right”. You might notice your horse pawing the ground, looking at its flank, or lying down more than usual. Some will stretch out as if to urinate, curl their upper lip, or grind their teeth. A reduced appetite is a major clue: leaving a favourite feed, picking at hay, or refusing treats. Droppings may become small, dry, or fewer in number. Mild restlessness, sweating for no reason, and a tucked-up appearance are also worth noting.

Get into the habit of checking vital signs when your horse seems off. A normal resting heart rate is around 28 to 44 beats per minute, respiration 8 to 16 breaths per minute, and temperature 37.5 to 38.5°C. A heart rate creeping above 60, rapid breathing, or pale gums are red flags. Write down the time you first noticed something and what you have seen. That information helps your vet enormously.

When colic becomes an emergency

Call your vet immediately if any of the following occur. Do not wait to see if things settle.

• Violent or continuous rolling, especially if your horse throws itself down and cannot be distracted.
• Pain that does not ease after 20 to 30 minutes, or that comes back in waves.
• No droppings for 12 hours or more, or straining with nothing produced.
• A visibly distended abdomen that looks bloated or drum-like.
• Rapid breathing, flared nostrils, or sweating without exercise.
• Heart rate over 60 beats per minute at rest, or gums that are pale, blue, or tacky.
• Depression or unresponsiveness, or a horse that seems to give up and stand still.

If you are unsure, ring the vet anyway. It is far better to call for advice than to wait and watch a mild colic become a surgical one. Trust your instincts: if your horse is behaving in a way that frightens you, that is reason enough to pick up the phone.

What to do while you wait for the vet

Keep yourself and your horse safe. Remove all feed, but leave fresh water available unless your vet advises otherwise. If your horse is rolling violently, do not put yourself in the way. Try to move it to a small, safe area such as a stable or a well-fenced pen with soft footing. Walking gently can sometimes help mild gas colic, but never force a horse that is lying down quietly or is exhausted. Do not give any medication, including painkillers, without veterinary guidance, as this can mask symptoms and delay diagnosis.

Have key information ready: your horse’s age, breed, usual diet, worming history, recent changes in routine, and the exact time symptoms started. Note whether it has passed droppings and what they looked like. If you can, take a photo of any unusual posture or behaviour. The more detail you can give, the faster your vet can decide on treatment.

Reducing the risk in daily care

While not all colic is preventable, good management lowers the odds. Feed little and often, with plenty of forage as the foundation. Make any feed changes gradually over at least a week. Ensure constant access to clean water, and check troughs and buckets in freezing weather. Keep on top of dental care so your horse chews properly, and follow a sensible worming programme based on faecal egg counts and veterinary advice. Regular exercise, turnout, and a consistent routine help keep the gut moving. Avoid sudden stress, long periods without food, and access to sandy or rich pasture that can cause impaction.

Trust your gut feeling

You know your horse better than anyone. A subtle change in attitude, a missed meal, or a single paw at the ground can be the first clue. Colic can escalate from mild discomfort to a life-threatening emergency in a matter of hours. Do not worry about being a nuisance. Veterinary teams would much rather see a horse early than arrive too late. If you are concerned, call. If the signs are severe, call immediately. Early recognition and quick action give your horse the best possible chance.
