Hearing that hollow, grating sound of your horse cribbing for the first time can be unsettling. You might feel worried, frustrated, or unsure what to do next. Cribbing (also called crib-biting or windsucking) is a stereotypy, meaning a repetitive, seemingly pointless behavior. But it’s not just a bad habit. It’s usually a sign that something in your horse’s environment or health needs attention. Let’s walk through why horses crib, what it means for their well-being, and how you can help them find healthier ways to cope.

What Exactly Is Cribbing and Why Do Horses Do It?

Cribbing involves a horse bracing its upper incisors on a hard surface (like a fence rail, stall door, or feed tub), arching its neck, and pulling backward while sucking in air. This often produces a distinct grunt or gulping sound. While the behavior looks odd, it’s believed to release endorphins, which can be calming for the horse. The most common triggers include:

  • Boredom and lack of turnout: Horses are natural grazers, designed to move and eat for 16+ hours a day. When confined to a stall with limited forage, they often develop cribbing as a coping mechanism.
  • Stress or anxiety: Changes in routine, weaning too early, competition pressure, or separation from herd mates can spark cribbing.
  • Gastric discomfort: Research strongly links cribbing to stomach ulcers. The act of sucking air may increase saliva production (which buffers stomach acid) and provide temporary relief from pain.
  • Genetics and learned behavior: Some breeds (like Thoroughbreds and Warmbloods) seem more prone. Foals may also learn the habit by watching a cribbing dam or neighbor.
Did You Know?

Not all windsucking is cribbing. Some horses suck air without grabbing a surface (called ‘free’ windsucking). And not every horse that cribs will develop health problems, but the risk is real. If your horse cribs, consider having your vet check for gastric ulcers, especially if they also show signs like poor appetite or mild colic.

Is Cribbing Dangerous for My Horse?

Cribbing itself isn’t always immediately harmful, but it can lead to serious issues over time. The most common physical consequences include:

  • Worn down teeth: Constant pressure on the incisors can cause uneven wear, making it harder for your horse to graze and chew properly.
  • Weight loss and poor condition: Cribbing can replace time spent eating, and the endorphin rush may reduce appetite. Horses that crib are also more prone to colic, especially epiploic foramen entrapment, a life-threatening type of colic linked to windsucking.
  • Muscle strain in the neck and jaw: The repetitive motion can lead to tension and discomfort in the throatlatch and poll area.

If your horse is an eventer, cribbing can also affect performance. A horse dealing with gastric pain or chronic stress may not have the focus or energy needed for training. For example, if you’re working on a eventing horse training schedule, a cribbing horse might be more distracted or resistant during flatwork. Similarly, a horse that cribs due to stomach discomfort may show subtle signs of lameness in eventing horses that are actually referred pain from the gut, not a leg issue.

“Cribbing is not a vice, it’s a voice. Your horse is telling you something isn’t right, and it’s your job to listen.”

How Can I Stop My Horse From Cribbing?

There is no magic cure, but you can significantly reduce cribbing by addressing the root cause. Here are the most effective strategies:

  • Increase turnout and social time: The single best fix is more time outside with a buddy. Horses are herd animals, and isolation is a major stressor. Even a few extra hours of turnout can make a huge difference.
  • Provide constant forage: Free-choice hay or a slow feeder keeps your horse’s gut busy and reduces boredom. Aim for at least 1.5% of body weight in forage daily.
  • Use cribbing collars wisely: A cribbing collar (a strap that tightens when the horse arches its neck) can discourage the behavior, but it’s a band-aid, not a solution. Never leave it on 24/7, and always pair it with environmental changes.
  • Manage diet and ulcers: Feed a low-starch, high-fiber diet. Alfalfa hay is naturally buffering for the stomach. Talk to your vet about a gastric ulcer treatment trial if you suspect pain. Knowing what do eventing horses eat can give you ideas for a gut-friendly diet that also supports energy needs.
  • Enrich the environment: Hang a likit, provide a jolly ball, or use a mirror in the stall. Anything that occupies your horse’s mind reduces cribbing time.
Important Note

Never punish a horse for cribbing. Punishment increases stress, which often makes the behavior worse. Instead, focus on meeting your horse’s physical and emotional needs. If your horse cribs so much that they’re losing weight or having repeated colic episodes, consult your veterinarian and an equine behaviorist.

Does Cribbing Affect a Horse’s Ability to Be Ridden or Competed?

It depends on the horse and the severity. Many cribbing horses go on to have successful careers, especially once their underlying issues are managed. However, cribbing can be a red flag for gastric ulcers, which directly impact performance. A horse with ulcers may be grumpy under saddle, refuse to bend, or resist collection. If you’re competing, you might notice your horse refusing jumps or spooking more easily. In fact, if you’ve wondered why does my eventing horse refuse jumps, cribbing-related discomfort could be a hidden factor. Similarly, a horse that cribs heavily may have poor topline development due to muscle tension in the neck, which can affect their ability to carry a rider correctly.

On the flip side, some competition horses crib for years without any apparent performance drop. The key is to treat the cause, not just the symptom. If you address the stress or pain, the cribbing often decreases naturally, and your horse will be happier and more willing to work.

Can Cribbing Be Prevented in Foals and Young Horses?

Prevention is much easier than breaking the habit. Here’s what you can do for young horses:

  • Delay weaning: Wean foals gradually, ideally after 6 months of age, and keep them with a companion.
  • Maximize pasture time: Foals and yearlings should live outside as much as possible. Stalled young horses are far more likely to develop cribbing.
  • Provide a consistent routine: Young horses thrive on predictability. Avoid frequent changes in feeding times, turnout, or herd mates.
  • Monitor diet: Limit grain and sugary feeds. A high-forage diet supports a healthy gut and reduces the risk of ulcers, which are a known trigger for cribbing.

If you’re considering an eventing prospect, it’s worth asking about the horse’s history. While are eventing horses good for beginners is a separate question, a young horse that starts cribbing early may need extra management to stay sound and happy in a training program.

When Should I Call the Vet About Cribbing?

You should involve your veterinarian if:

  • Your horse starts cribbing suddenly (especially an older horse with no history).
  • The cribbing is accompanied by weight loss, poor coat, or colic symptoms.
  • Your horse shows signs of dental pain, such as dropping feed or head tilting while eating.
  • You’ve tried environmental changes for several weeks with no improvement.

A vet can perform a gastroscopy to check for ulcers, do a dental exam, and help you create a comprehensive management plan. Remember, cribbing is a symptom, not a moral failing. With patience and the right changes, you can help your horse live a more comfortable, crib-free life.
