Colic is scary and can come out of nowhere. It's the #1 cause of death in horses and can range from the mildest of cases that self correct, to the more severe that require quick intervention. Read Colic: How To Defend, Diagnose and Deal to help you minimize your horse's risk of suffering from colic, while letting you know what to look for, as well as what to do if symptoms occur.
Colic is not a disease, but a symptom of distress in a horse's abdomen (gut or belly). Although it's not possible to prevent colic, there are practices you can put in place to minimize the risk of colic in your horse. The American Association of Equine Practitioners (AAEP) has compiled the following recommendations:
- Establish a daily routine to include feeding and exercise schedules and stick to it.
- Feed a high quality diet comprised primarily of roughage.
- Avoid feeding excessive grain and energy-dense supplements. (At least half the horse's energy should be supplied through hay or forage. A better guide is that twice as much energy should be supplied from a roughage source than from concentrates.)
- Divide daily concentrate rations into two or more smaller feedings rather than one large one to avoid overloading the horse's digestive tract. Hay is best fed free-choice.
- Set up a regular parasite control program with the help of your equine practitioner.
- Provide exercise and/or turnout on a daily basis. Change the intensity and duration of an exercise regimen gradually.
- Provide fresh, clean water at all times. (The only exception is when the horse is excessively hot, and then it should be given small sips of luke-warm water until it has recovered.)
- Avoid putting feed on the ground, especially in sandy soils.
- Check hay, bedding, pasture, and environment for potentially toxic substances, such as blister beetles, noxious weeds, and other ingestible foreign matter.
- Reduce stress. Horses experiencing changes in environment or workloads are at high risk of intestinal dysfunction. Pay special attention to horses when transporting them or changing their surroundings, such as at shows.
You can follow all of the above recommendations and colic may still occur. Identifying and recognizing symptoms right away is the key to helping a horse in distress. Hereâ¬"s what to look for in a horse that may be suffering from colic:
- Pawing the ground
- Kicking or biting at the belly
- Excessive sweating not related to external temperature or work
- Turning the head toward or into the flank
- Putting the head down to water, but not drinking
- Stretching out as if to urinate, without doing so
- Head is held in an unusual position
- Teeth grinding or lip curling unrelated to sexual interest
- Trying to or repeatedly lying down and getting up
- Repeated rolling, often with grunting sounds
- Sitting in a dog-like position, or lying on the back
- Leaving food or being completely disinterested in food
- Lack of bowel movements or fewer bowel movements than normal
- Reduced or absent digestive sounds
- Rapid breathing and/or flared nostrils
- Elevated pulse rate (greater than 50 beats per minute)
- Depression

If you notice any one of these signs you need to be vigilant and monitor your horse's behavior for an extended period of time. Whenever you suspect your horse may be suffering from colic, call your vet to alert him or her of your suspicions. If the colic appears mild in nature, your vet will more than likely have you walk your horse and watch for the passing of gas and bowel movements. It's good for your vet to know the situation early on, so if rapid measures are necessary later, everyone will be prepared. Having the following information when talking to your vet will help everyone assess the situation, even if your vet is not immediately able to be on site:
- Describe what you're physically seeing in your horse that makes you suspect colic from the symptoms listed above.
- Basic Vital Signs (temperature, pulse, respiration & gut sounds):
Temperature: To take your horse's temperature we recommend using an electronic rectal thermometer (check your tack/feed/or supply catalogs). Moisten the end going into your horse's anus with petroleum jelly. Tie your horse and insert the thermometer about two inches. Typically you'll need 30 seconds to get an accurate reading. Your horse's normal temp should be between 99 and 101.5.
Respiration: Simply watch the rise and fall of the flank with each flank and count how many times this occurs within a minute.
Pulse: We recommend you have a stethoscope in your barn emergency kit. Position the head of the stethoscope against the chest wall beneath the left elbow and then move the scope as far forward under the elbow as possible. You will count the number of beats during a 15 second period and multiply by four. Your horseâ¬"s normal heart rate is between 30 and 40 beats per minute (bpm). You can also use your fingers to acquire the same calculation by placing a finger over an artery (sides of fetlock or under the jaw are two of the easiest spots).
Gut Sounds: Still using the stethoscope listen to your horses gut sounds in the lower flank and upper flank on each side of your horse for at least one minute per placement. You should hear two to four gurgles per minute and a louder grumble every few minutes. You can also simply press your ear against your horses flank for almost the same result. If you hear nothing, you horse may be experiencing a severe colic.
- Gum Assessment:
Visual: What do the gums look like? Are they white, pale pink, dark pink, red or bluish-purple?
Moisture: Are they moist, tacky, or dry?
Color Replacement: How much time does it takes for the color to return to the horse's gum after you briefly press on the gum with your thumb?
- Bowel Assessment: Last noted, including color, consistency, and frequency
- Routine: Describe any recent changes in management, feeding or exercise
- History:
Medical: Know what and when of recent vaccinations, deworming and any past episodes of colic
Breeding: Know your horse's pregnancy status if a mare, and recent breeding history if a stallion
- Insurance: Know if your horse has major medical and the requirements for treatment. This is especially important if surgery is contemplated to save your horse's life.
Remember, it's not just the more obvious pawing or trying to roll that indicates colic. Lethargy and a diminished appetite or any change in your horse's disposition can indicate an issue. Knowing your horse and his behavior will help you know when something is "Soff" and if colic is a possibility. Although colic is one of the most frightening words in a horse person's vocabulary, most cases, when caught early, are resolved with moderate medical treatment (analgesics and either fluids or laxatives). Preparation and keeping your head about you is the key to navigating any unusual situation in your horse's health.
