Why Mild Colic Is So Easily Missed
When people think of colic, they often picture a horse violently rolling, sweating, and clearly in distress. In reality, many colic cases start far more quietly.
Mild colic is one of the most commonly missed health issues in horses because the signs can be subtle, inconsistent, and easy to explain away. Horses may still be eating, still be standing, and still look “mostly fine” — yet something is not right internally.
Learning to recognise the early signs of mild colic in horses gives you a crucial head start. Acting early can prevent a mild digestive issue from developing into a serious emergency.
This article explains what mild colic really looks like, how it differs from more severe cases, and what horse owners should do when something feels slightly off.

What Is Mild Colic?
Mild colic refers to low-level abdominal discomfort rather than severe pain. It may be caused by gas, slight gut spasms, mild dehydration, or small digestive disturbances.
In many cases, mild colic:
- Develops slowly
- Comes and goes
- Causes vague behavioural changes
- May resolve with prompt management or veterinary treatment
Because horses are prey animals, they are very good at hiding pain — especially low-level discomfort. This is why mild colic often shows up as behavioural changes rather than dramatic symptoms.
Subtle Behaviour Changes That Can Indicate Mild Colic
One of the earliest warning signs is a change in normal behaviour. Owners often describe this as their horse being “not quite themselves”.
Common behavioural clues include:
- Standing quietly but looking dull
- Less interest in surroundings
- Standing away from field mates
- Slower reactions than usual
- Reduced curiosity
These signs are easy to overlook, particularly in calm or older horses.
A good rule of thumb is this:

Changes in Eating and Drinking Habits
Appetite changes are one of the most reliable early indicators of mild colic.
You may notice:
- Eating more slowly
- Leaving part of a feed
- Picking at hay instead of eating normally
- Refusing treats they would usually take
Some horses will continue to eat despite discomfort, so a reduced appetite should never be ignored — but normal eating does not rule colic out.
Drinking behaviour may also change:
- Drinking less than usual
- Only taking small sips
- Avoiding cold water
Reduced water intake is particularly important, as dehydration is both a cause and a consequence of colic.
Mild Physical Signs of Colic
Unlike severe colic, mild cases often show intermittent physical signs rather than constant pain.
Common mild physical signs include:
- Occasional pawing at the ground
- Turning the head towards the flank
- Stretching out as if to urinate
- Lifting the tail repeatedly
- Shifting weight from side to side
These behaviours may appear briefly, disappear, and then return later. This on-and-off pattern is typical of mild colic and one reason it is often dismissed.
Lying Down More Than Normal
Horses with mild colic often lie down more frequently, but without violent rolling.
You might see:
- Lying down in the stable when they usually stand
- Lying down briefly, then getting up
- Lying flat but appearing calm
This behaviour can easily be mistaken for tiredness or relaxation, especially after turnout or exercise. However, a change from normal resting habits is worth paying attention to.
Droppings: One of the Most Important Clues
Droppings provide valuable insight into gut health and are often overlooked.
Signs to watch for:
- Fewer droppings than normal
- Smaller or drier droppings
- Droppings that look unusually firm
- Mild diarrhoea or loose droppings
Any noticeable change in droppings, especially alongside behavioural changes, should raise concern.
Checking droppings daily is one of the simplest and most effective ways to spot digestive issues early.
Gut Sounds: Quiet Isn’t Always Good
If you are experienced and confident listening to gut sounds, changes can sometimes indicate mild colic.
- Very quiet or absent gut sounds can suggest reduced gut movement
- Loud, gurgling sounds may indicate gas
However, gut sounds alone are not a reliable diagnostic tool for owners and should never replace veterinary advice.
How Mild Colic Differs From Severe Colic
Understanding the difference helps owners make better decisions.
Mild colic typically:
- Causes low-level discomfort
- Allows the horse to remain standing
- Shows intermittent signs
- May improve temporarily
Severe colic:
- Causes continuous or escalating pain
- Often involves violent rolling
- Leads to sweating and distress
- Requires urgent veterinary intervention
Mild colic can become severe if left untreated — which is why early recognition matters so much.

Common Situations Where Mild Colic Develops
Mild colic often appears following routine changes that seem harmless at the time.
Common triggers include:
- Slight changes in forage
- Reduced water intake in cold weather
- Increased stabling
- Light stress (travel, routine disruption)
- Changes in grazing
Because these situations are common, owners may not immediately connect them to colic symptoms.

What To Do If You Suspect Mild Colic
Early action is key, even when signs are mild.
Step 1: Remove Hard Feed
Remove concentrates and treats immediately. Follow veterinary advice regarding forage.
Step 2: Encourage Water Intake
Ensure fresh, clean water is available and easily accessible.
Step 3: Monitor Closely
Watch for:
- Increased discomfort
- Rolling
- Sweating
- Worsening behaviour
Step 4: Call the Vet If Unsure
Never worry about “overreacting”. Vets would rather assess a mild case early than treat a severe one later.

Why Owners Hesitate — and Why They Shouldn’t
Many owners delay action because:
- The horse is still eating
- The signs seem minor
- They don’t want to “make a fuss”
Unfortunately, this delay is one of the most common reasons mild colic becomes serious.
Trust your instincts. If something feels wrong, it usually is.
Preventing Mild Colic From Occurring
While not all colic can be prevented, good management reduces risk significantly.
Key prevention measures:
- Make feed changes gradually
- Provide constant access to clean water
- Maintain regular turnout
- Avoid long periods of inactivity
- Monitor droppings daily
Small, consistent routines are often more effective than major interventions.

Mild colic
Mild colic is not always dramatic — and that’s exactly what makes it dangerous. The ability to recognise small changes in behaviour, appetite, and routine is one of the most valuable skills a horse owner can develop.
Early recognition, calm action, and good management give horses the best chance of a quick and uncomplicated recovery.
Frequently Asked Questions About Mild Colic in Horses
In some cases, mild colic can improve on its own, especially if it is caused by minor gas or temporary digestive upset. However, colic can worsen quickly, so horses should always be monitored closely. If symptoms persist, worsen, or return, a veterinarian should be contacted promptly.
Mild colic symptoms may last anywhere from a few minutes to several hours. Short-lived episodes can still be significant, as colic can progress unpredictably. If signs last longer than 30–60 minutes or recur, veterinary advice is recommended.
A vet should be contacted if mild colic symptoms do not improve, if the horse becomes more uncomfortable, stops eating or drinking, or shows repeated episodes of pain. Early veterinary involvement is always safer than waiting for symptoms to worsen.
Early signs of mild colic often include restlessness, reduced appetite, flank watching, stretching as if to urinate, changes in manure, or a dull or withdrawn attitude. These subtle symptoms are easy to miss but are important early warning signs.
Even mild colic should be taken seriously. While some cases remain minor, others can progress into more severe forms of colic. Recognising early signs and responding quickly helps reduce the risk of complications.
Yes. Sudden changes in diet, feeding large grain meals, poor-quality forage, or inadequate water intake are common triggers for mild colic. Gradual feed changes and good hydration are key to reducing colic risk.
Light movement, such as gentle hand-walking, may help in some mild cases, but forced exercise should be avoided. If the horse appears uncomfortable or symptoms worsen, stop and contact a vet.
