Summer Colic: The Warning Signs Owners Miss
The dramatic presentation is easy to recognise. The quiet one is far more common, and it is the one that costs time.
Everyone knows the picture. A horse down in the stable, rolling, sweating, getting up and going down again. That version of colic announces itself, and nobody misses it.
The version worth writing about is quieter, because it is more common and because the delay between noticing and acting is where the damage happens.
Before anything else: colic is not a diagnosis. It is a word for abdominal pain, and the causes behind it range from mild and self resolving to genuinely life threatening. Nothing in this article substitutes for a vet. It is about noticing sooner.
The quiet signs
A horse in early or mild abdominal discomfort often does not roll or thrash. It does smaller things.
It goes off its feed, or picks at it rather than eating properly. For most horses this is deeply out of character and is the single most useful thing an owner notices.
It turns and looks at its own flank, repeatedly. Not once, which means nothing, but as a pattern.
It paws at the ground. It stretches out as though trying to urinate without producing anything. It lies down more than usual, or lies down at odd times, or keeps getting up and down.
It stands apart from the others, or stands unusually still, or seems dull in a way that does not match the horse.
Droppings reduce, change consistency, or stop.
Any one of these on its own may be nothing. Several together, or one that persists, is worth acting on.
The most valuable diagnostic instrument on any yard is somebody who knows what that particular horse normally does.
Why knowing the normal matters so much
None of the signs above mean anything in isolation. Plenty of horses paw. Plenty of horses lie down in the afternoon sun.
What makes them meaningful is deviation. This horse, which always finishes its feed, has left half of it. This horse, which never lies down during the day, has been down twice this morning.
That is why the owners who catch things early are not the ones with the most equipment. They are the ones who look at the same horse every day and notice when the pattern breaks.
The summer specifics
A few things make the warmer months their own case.
Water intake matters more and is easier to get wrong. Horses drink less when troughs are warm, stale, or awkward to reach, and reduced intake is a recognised risk factor for impaction. Clean water, checked and refilled, is not a small thing.
Grazing changes. Bare, overgrazed summer paddocks encourage horses to take in sand and grit along with what is left of the grass, which carries its own risks in some regions.
Routine changes cluster in summer: travelling to shows, different fields, changes in turnout hours, unfamiliar forage away from home. Sudden change is a recognised trigger, and summer is when most of it happens.
What to do
Call the vet. That is the entire recommendation, and it should come earlier rather than later.
While waiting, take the horse off feed and remove any remaining hay, so nothing more is going in. Note when you first noticed something, what you saw, and whether it is getting worse. Your vet will ask.
Do not medicate on your own initiative. Pain relief given before a vet has examined the horse can mask exactly the signs they need to assess.
And do not sit on it to see whether it passes. The mild cases resolve, and a vet visit for a horse that turns out to be fine is the cheapest possible outcome of the day.
