Stable behavior
Why does my horse crib?
Equiteca Editorial · Reviewed 2026-08-30 · 3 sources
A cribbing horse grabs a solid edge with its top teeth, arches its neck, and sucks in air with a grunt. It is a stereotypy, a repetitive behavior that develops when a horse cannot meet its basic need to forage and move. Cribbing is not a horse being naughty or copying its neighbor, and it is strongly tied to how the horse is fed and kept. It also links to gut discomfort: young horses with gastric ulcers are more likely to crib, and treating the ulcers often cuts the cribbing down. The behavior is a signal that the horse's routine or its stomach needs attention, not a habit to punish out of it.
What it looks like
- Grabs a fence rail, door, bucket lip, or other firm edge with the top teeth
- Arches the neck, pulls back, and gulps air with a grunting or belching sound
- Worn, angled front teeth and chewed or splintered wood on stall and fence edges
- Cribs most before feeding, on box rest, or when turnout and forage run short
- Poor condition, weight loss, or bouts of colic in some long-term cribbers
Likely causes, ranked
A tag marks the causes that are pain wearing a behavior label. Those are the ones to rule out first.
A horse is built to graze most of the day. Long gaps with no forage and a high-grain, high-concentrate diet are among the most consistent triggers for cribbing. More roughage and less grain lowers the risk and often reduces the behavior.
Cribbing is linked to gastric ulcers, especially in young, growing horses. Air-gulping and the acidic, low-forage conditions that go with it are tied to stomach inflammation. In studies, treating the underlying gastric disease tended to reduce time spent cribbing, so ulcers are worth ruling out.
Horses kept stabled for long stretches with limited turnout are far more likely to develop stereotypies. Time out of the stable to walk, graze, and explore lowers the drive to crib, though it rarely erases an established habit.
Horses are herd animals. Being unable to see, touch, or interact with other horses is one of the management factors tied to stereotypic behavior developing in the first place.
Once cribbing is set, it can persist even after management improves, because the behavior itself releases tension for the horse. This is why prevention beats cure, and why an established cribber usually needs managing rather than a full fix.
What to try
- 1Rethink forage and feedMove toward more forage and less grain. Give near-constant access to hay or grazing, use a slow-feeder or small-hole net to stretch feeding out, and cut high-concentrate meals where you can. This addresses the most consistent driver of cribbing.
- 2Add turnout and companyMaximize daily turnout and let the horse see and interact with others. More time grazing and moving, and more social contact, lowers the pull to crib. Keeping a horse in isolation to stop it copying others is not supported by the evidence.
- 3Talk to your vet about ulcersBecause cribbing links to gastric ulcers, ask your vet whether gastroscopy or a treatment trial makes sense, especially in a young horse or one that also drops weight, eats poorly, or has loose droppings.
- 4Manage the behavior, do not just block itA cribbing collar makes the movement uncomfortable but does not fix the cause, and some horses crib more once it comes off. Fix the routine first. Use physical measures only alongside better management, never instead of it.
When to call the vet
- The cribbing is new, or has clearly increased
- The horse is losing weight, eating poorly, has a dull coat, or has loose droppings
- There are signs of colic: pawing, rolling, looking at the flank, going off feed
- You want to rule out or treat gastric ulcers, especially in a young horse
- The teeth are wearing badly, which can affect grazing and needs a dental check
Not sure it is behavior or pain? How we frame it.
Behavior or pain?
Cribbing gets written off as a vice, a bad habit, or one horse copying another, and none of that holds up well. It is a stereotypy that develops when a horse cannot forage and move as it needs to, and it runs alongside gut discomfort: young horses with gastric ulcers crib more, and treating the ulcers tends to reduce it. The useful way to read cribbing is as feedback on management and on the stomach. Punishing it or strapping a collar on without changing the forage, turnout, and company misses the point, and can leave a painful ulcer untreated underneath.
Questions people ask
Will my other horses learn to crib by watching?
The old belief that cribbing spreads by copying is not backed by the evidence. Only a tiny fraction of horses take it up after being around a cribber. Horses develop cribbing mainly from their own management, low forage, little turnout, and stress, not from a neighbor.
Should I use a cribbing collar?
A collar makes cribbing physically uncomfortable, so it can reduce the behavior while worn, but it does not address why the horse cribs, and some horses crib harder once it is removed. Fix forage, turnout, and company first, and treat any ulcers. Use a collar only as a support alongside those changes.
Is cribbing bad for my horse's health?
It can be. Cribbers wear their front teeth abnormally, and the behavior is associated with a higher risk of certain colics and with gastric ulcers. That is why cribbing is worth investigating with your vet rather than just tolerating or blocking.
