A Horse that Windsucks

Q:

What can be done for a horse that windsucks?

A:

The term "windsuck" is used for two separate and unrelated problems which happen at opposite ends of the horse.  The more common use of the term refers to the behavior characterized by the horse bracing its upper incisors onto a firm object and arching the neck while taking air into their esophagus, generating an audible grunting sound (note: this is not the same as woodchewing).  This type of windsucking is also called "Cribbing."  The behavior is an an example of a "stereotypical" behavior, a repetitive behavior with no apparent reason or purpose.  "Stereotypical" behaviors are addictive and, once started, they are very difficult to eliminate.  Studies suggest that less access to foraging and socializing with other horses leads to an increased risk for developing "stereotypical" behaviors.  Cribbing is an undesirable behavior and can lead to dental problems, weight loss (because of cribbing when they should be eating), and poor condition.  "Cribbers" are less marketable because of these associated problems. 
 
Because it is undesirable numerous strategies have been developed to try and control the behavior.  Various "cribbing straps" have been developed that fit around the horse's neck that make it more difficult and uncomfortable to crib.  Applying noxious chemicals to surfaces is another method some have tried.  Another is use of electric tape or wire to create a barrier to surfaces commonly used for cribbing (e.g. stall walls).  There is a fairly radical surgery that has been used in which the muscles used for flexing the neck to crib are cut.  Cribbing behavior is strongly addictive and often the drive to crib will overcome these prevention methods - in other words the horse will find a way because the drive is so strong.  The most one can hope for with these methods is a reduction in the behavior.
 
Some recent evidence suggests that cribbing is a coping mechanism and as such it might not be helpful to the horse to make it difficult, painful, distasteful or physically incapable of performing the behavior.  Instead the focus should be directed at reducing the drive to crib in the first place.  Promoting management practices that encourage foraging behavior (e.g. turn out on pasture) and socializing with other horses help reduce cribbing.  Cribbing is so powerfully addictive that reducing, not eliminating, the behavior is the best we can hope for.
