When it comes to performance horses, the single most important thing to understand about colic is that early detection is critical. Performance horses, often in intense training and competition, are at higher risk for colic due to stress, dehydration, and dietary changes. Our editorial team emphasizes that recognizing subtle signs can make the difference between a mild episode and a life threatening emergency.
Performance horses may show signs of colic differently than pasture horses. They are often stoic and may mask discomfort until it becomes severe. Owners must be vigilant for any deviation from normal behavior, especially during or after training sessions.
Behavioral Changes in Performance Horses
Performance horses have distinct routines and temperaments. The first signs of colic often involve subtle behavioral shifts. A horse that is normally eager to work may become dull, reluctant to move forward, or resistant to cues. Conversely, a calm horse may become agitated, pawing the ground or looking at its flank. These changes are especially noticeable during warm up or competition.
In the stall, watch for restlessness: circling, lying down and getting up repeatedly, or standing with the head turned toward the belly. Some horses may yawn excessively or stretch as if trying to urinate. Because performance horses are often handled intensively, any deviation from their usual attitude should raise suspicion.
Physical Signs of Discomfort
Physical examination can reveal colic signs. A performance horse may have an elevated heart rate (above 40 beats per minute at rest) or respiratory rate. Capillary refill time may be prolonged beyond 2 seconds. Gum color can become brick red or bluish. Listen for absent or reduced gut sounds on both sides of the abdomen. A horse that kicks at its belly or looks back frequently is often in pain.
Sweating in a horse that is not working hard is a red flag. Some horses will have muscle tremors, especially over the flank. In performance horses, dehydration can worsen colic: check skin tenting over the neck or shoulder. A horse that refuses to drink after exercise is concerning. Observing these signs early can prompt intervention before the condition progresses.
Digestive and Appetite Changes
Performance horses are typically fed a high energy diet with concentrates and hay. A sudden loss of appetite or refusal to eat grain is a common early warning. Some horses may eat hay but leave grain, or vice versa. They might take small amounts of water frequently or avoid drinking altogether. Reduced manure output or dry, mucus coated fecal balls can indicate impaction colic, which is common in performance horses due to limited turnout and high grain diets.
Watch for a horse that lies down more than usual or gets up and down frequently. Rolling violently is a sign of severe pain, but many performance horses will just stand quietly and appear depressed. Changes in manure consistency or frequency should be noted. In some cases, the horse may pass small amounts of manure or none at all for several hours. Recognizing these digestive cues is vital for timely veterinary care.
When to Call the Veterinarian
Any persistent sign of colic in a performance horse warrants a veterinary call. Do not wait for the horse to roll violently or show extreme pain. If the horse has a heart rate over 48, no gut sounds, or is continuously pawing and sweating, contact your veterinarian immediately. Performance horses may deteriorate rapidly due to their high metabolic rate and stress.
While waiting, remove all feed but provide water if the horse will drink. Do not walk the horse excessively; gentle hand walking can be helpful if the horse is calm and not in danger of falling. Never administer pain relievers without veterinary guidance as they can mask symptoms. Your veterinarian will perform a rectal exam and possibly pass a nasogastric tube. Early intervention often resolves colic with medical treatment, avoiding surgery. Being proactive is the best way to protect your performance horse’s health and career.
