It's 2026. Where are we at with cribbing research??
Hereās what the latest cribbing research shows.
1) Cribbing isnāt bad behavior.
Itās a stress-coping mechanism, developed by horses in high stress environments or management systems that donāt meet their natural needs. Top contenders for this are early weaning and confinement.
2) It literally affects the brain.
Studies show cribbing is linked to changes in the striatum and dopamine pathways, the same parts of the brain involved in habit formation. Thatās one reason cribbing can become nearly permanent once established. Scientists found "cribbing horses blink less often and change up their activities more often than noncribbers." Further proving that cribbing horses have striatums that behave differently that those of non cribbers.
3) There may be a genetic predisposition.
Certain breeds like Thoroughbreds and Warmbloods show higher rates, suggesting some horses are more wired to develop cribbing than others. But no confirmed link has been found directly tying cribbing to a certain gene.
4) The gut and brain are connected.
Cribbing horses have different hindgut microbial communities than non-cribbers, supporting a link between stress, digestion, and brain behavior. This could be due to stress.
5) It isnāt simply about ulcers.
Earlier theories that cribbing was a way to neutralize stomach acid donāt hold up. Research shows no clear direct connection between the behavior and gastric ulcers.
6) Cribbing is associated with other health risks.
Long-term cribbing can wear down teeth, affect eating, and is correlated with increased risk of colic and joint issues.
7) Cribbers can have different learning and sensitivity profiles.
One study tested cribbers and non cribbers on their ability to pick up a new task, touching a card for a food reward. Cribbers were much quicker learners, but also "they take longer than noncribbers to stop trying for that reward, continuing to touch the card well after it no longer leads to a food reward." This study suggests a higher habit formation in cribbers. They also found cribbers to be more sensitive to touch, likely due to how stress and brain function intersect.
8) Management matters more than āfixes.ā
Equipment like anti-cribbing collars or toys can reduce the frequency, but the best way to reduce cribbing is to address stressors: more turnout, social contact, and natural feeding patterns. Once it starts, its unlikely to stop, though.
9) Some experimental treatments show promise.
In one case, daily CBD was linked with a dramatic drop in cribbing hours, but this is early data and not yet a standard practice.
10) Horses donāt catch cribbing from each other.
Contrary to popular belief, thereās no strong evidence that one horse āteachesā another to crib... itās more about shared stress and management conditions.
Bottom line: cribbing isnāt a horse being bad. Itās often the horseās way of coping with stress or unmet needs. The real solution isnāt suppression, itās better welfare: turnout, forage, and a life closer to what horses are built for from the beginning to prevent the habit from forming in the first place.
