Position on the Use of Hog Rings

Cribbing (also known as crib biting or windsucking) is one of many abnormal repetitive behaviors known as stereotypies, which are sometimes demonstrated by horses. Horses exhibiting cribbing should be evaluated by a veterinarian to assist in determining underlying causes of this behavior. Cribbing is a complex, multifactorial condition and should be managed on an individual level. Preventing the horse from performing the stereotypy without addressing its cause may lead to further stress, frustration, and the emergence of other stereotypies. A horse may continue to perform stereotypies even after the predisposing factors have been addressed. This does not necessarily indicate their current welfare status is poor.¹

A variety of devices have been utilized to prevent horses from cribbing, including hog rings. The AAEP opposes the use of hog rings or other devices in the oral cavity to prevent cribbing in horses. These devices are detrimental to the welfare and health of the horse due to the potential to cause persistent pain, damage to the gingiva, periodontal disease and abrasive wear to adjacent teeth.
