How to Stop a Horse From Cribbing: A Practical Owner’s Guide

If you own a horse that cribs, you know the sound all too well: that hollow, gulping grunt as your horse grabs a fence board, stall door, or even a water trough and sucks in air. It is not just annoying, it can lead to worn teeth, weight loss, and even colic. The good news is that while you may not be able to “cure” cribbing entirely, you can absolutely manage it and reduce the behavior significantly. The key is understanding why your horse does it and then making smart changes to his environment and routine. Let’s get into what actually works.

Understand Why Horses Crib in the First Place

Cribbing is a stereotypy, meaning it is a repetitive, compulsive behavior that often stems from stress, boredom, or a high-concentrate diet. Horses are natural grazers meant to roam and eat small amounts all day. When they are stalled for long hours or fed large grain meals with little forage, they can develop this oral fixation. Some studies suggest a genetic predisposition, but the environment is the biggest trigger. Think of it as your horse’s way of self-soothing. Before you try to stop it, ask yourself: is my horse getting enough turnout, social time, and forage? Addressing those three factors is the foundation of any cribbing management plan.

Adjust Your Horse’s Diet and Forage

One of the most effective ways to reduce cribbing is to mimic a horse’s natural feeding pattern. Increase hay or pasture time so your horse is constantly chewing. You can also use a slow feeder hay net or a grazing muzzle to extend eating time. If you feed grain, consider reducing the amount or switching to a low-starch, high-fiber feed. A sudden spike in blood sugar from grain can trigger cribbing. For eventing horses who need extra energy, it is important to balance their diet carefully.

Always make fresh water available, as some horses crib more when dehydrated.

Use a Cribbing Collar Correctly

A cribbing collar is a strap that fits around the horse’s throat. When the horse tries to arch his neck and suck air, the collar tightens slightly, making it uncomfortable to complete the motion. These collars do not hurt the horse, but they are a management tool, not a cure. Fit is critical: too loose and it won’t work, too tight and it can cause rubs or restrict breathing. Use a fleece-lined collar and check it daily. Never leave a cribbing collar on a turned-out horse unsupervised, as it can catch on fencing. Many owners use the collar during stall time only. And remember, the collar stops the action but not the urge, so pair it with the other strategies below.

Enrich the Stall and Turnout Environment

Boredom is a huge driver of cribbing. If your horse is stalled for long periods, he needs mental stimulation. Hang a jolly ball, a salt lick, or a treat-dispensing toy in his stall. You can also place a mirror designed for horses, which some studies show reduces stereotypies. Turnout is even better: aim for as many hours as possible with a buddy. Horses are herd animals, and social isolation is a major stressor. If your horse is an eventer, you might worry about keeping him sound and happy. A calm, enriched environment helps his overall well-being and can even improve performance.

Make Physical Changes to the Stable

If your horse cribs on stall doors, fences, or gates, you can make those surfaces less appealing. Cover the edges of doors with metal cribbing guards, plexiglass strips, or even old tires cut in half. You can also paint wooden surfaces with a bitter-tasting anti-cribbing paint (available at most feed stores). Another trick: install a wooden or rubber grid on the stall door that makes it uncomfortable to grip. For horses that crib on the top edge of a stall wall, raise the height of the wall or add a roller. These are deterrents, not solutions, but they can buy you time while you work on the root causes. If you are building or remodeling a stable, consider the eventing horse stable size requirements to ensure your horse has enough room to move and lie down, which reduces stress.

When to Call Your Vet

Cribbing can lead to real health problems. Over time, it wears down the upper incisors, which can affect grazing. It can also cause excessive salivation, weight loss, and in severe cases, colic from swallowing too much air. If your horse starts cribbing suddenly, or if the behavior becomes more intense, call your vet. There are also medical options, such as surgical procedures (like a modified Forssell’s procedure) that cut certain neck muscles, but these are last-resort measures with risks. Always discuss behavior modification and diet changes with your vet first. They can also check for underlying pain, such as from ulcers or lameness, which can trigger cribbing. A horse that is uncomfortable may crib to release endorphins.

“You cannot punish a horse out of cribbing, but you can manage him into a happier, healthier life.”

Consistency and Patience Are Your Best Tools

Stopping cribbing is rarely a quick fix. It takes a combination of diet changes, environmental enrichment, and sometimes a collar. Keep a journal of when and where your horse cribs most, and adjust your approach. Some horses improve dramatically with just more turnout and a slow feeder. Others need the full toolkit. And if you have an eventing horse, remember that stress from training can contribute. Make sure your horse is getting enough rest and recovery. A well-rested horse is less likely to develop compulsive habits.

You are not alone in this, and with time, you can help your horse feel better and crib less.
