Signs of Colic in Horses: What to Watch For
"Colic" isn't one disease — it's the umbrella term for abdominal pain, and it ranges from a mild gas spasm that passes in twenty minutes to a surgical emergency. Because you can't tell which one you're looking at from the first symptom alone, the safe habit is the same every time: call the vet early, and describe exactly what you're seeing.
Early signs to watch for
- Reduced or absent droppings, or droppings that look drier or smaller than normal for that horse.
- Pawing the ground, repeatedly looking at or nipping the flank.
- Lying down more than usual, or getting up and down repeatedly and restlessly (distinct from a normal, relaxed nap).
- Reduced interest in feed or water, especially in a horse that's normally a good eater.
- Sweating without exertion, elevated resting pulse, or a tucked-up, uncomfortable stance.
- Rolling, particularly violent or repeated rolling rather than a single roll-and-shake after turnout.
Not every horse shows every sign, and mild wind colic can look alarming for ten minutes and then resolve completely. That's exactly why you call rather than guess — the vet, not you, decides whether it's urgent.
Why speed matters more than severity
A horse can go from mild discomfort to a genuine emergency within an hour. Vets consistently say the same thing: call at the first signs, not once you're certain it's serious. A vet talking you through what to watch for over the phone costs you nothing but a call; waiting to "see if it settles" is the decision that turns a manageable case into a harder one.
What the vet will want to know
Having this ready before you call saves time that matters:
- When you last saw the horse completely normal, and what changed since.
- Resting pulse, gum colour and capillary refill time if you can safely check them.
- Whether droppings have been passed, and roughly when.
- Recent changes: feed, turnout, water source, weather, travel, or a recent worming or dental visit.
- Whether this horse has colicked before, and how that episode went.
This is exactly what a health log is for. If you've been recording weight, appetite and normal vitals in your horse's profile (see what to record in a health log), you already have the "last seen normal" answer instead of guessing under pressure.
While you wait for the vet
Follow your vet's specific instructions on the call — they may want the horse walked gently, or kept still and quiet, depending on what they're hearing from you. Remove feed, keep water available unless told otherwise, and keep the horse somewhere safe to move if it wants to lie down. Do not give any medication without veterinary direction; masking pain can hide how the case is actually progressing.
Reducing the risk
No routine eliminates colic risk entirely, but consistent habits lower it: steady access to forage, gradual feed changes, regular turnout, a reliable worming programme, and dental checks that keep chewing efficient. Weight and appetite trends logged over time (not just remembered) are often the first hint that something in the routine needs a second look — our laminitis and spring turnout guide covers a related example of a seasonal risk that shows up in the same kind of data first.
Log it after, not just during
Once the vet visit is over, record the diagnosis, treatment and any follow-up date while it's fresh. A pattern of mild episodes is information a vet needs to see across months, not recall from memory during the next emergency call. YardForge's horse health records keep that timeline, plus recurring reminders, against each horse's profile so it's there the next time you need it.
