Cribbing and windsucking are two different things. Both cribbing and windsucking involve the ingestion of air. The horse gulps air into the esophagus as it breathes, which sometimes causes a gurgling sound in the throat. However, cribbing and windsucking differ in the way the horse uses its tongue. In cribbing, the horse protrudes its tongue while it cribs. In windsucking, the horse holds its tongue back so that only a small amount of air comes into contact with the tongue.
While cribbing and windsucking are both considered abnormal behaviors, cribbing is more common. Both cribbing and windsucking can lead to potential health issues if the behavior becomes chronic.
It's important to get help for your horse if it cribs or windsucks excessively, but cribbing is generally easier to treat than windsucking.
