Whether called cribbing, wind sucking, or aerophagia, it is a destructive habit in horses caused by boredom and stress and possibly stomach acidity. Once the habit is learned there is no sure remedy for breaking it. Foals can learn to crib from their mothers and young horses may learn it from others. Before you buy a horse, pony, donkey or mule that cribs make sure you are willing to deal with the damage to fences, trees, and stables and cope with the possible health risks.
