Cribbing—also known as crib-biting—is a somewhat rhythmic, repetitive behavior that seems to have no purpose. Scientists have been getting to the root of equine cribbing as they explore brain anatomy, genetics, potential causes, health consequences, welfare, treatment, and more.

This article explains what we’ve learned about cribbing in the last eight years.
