Position on the Use of Hog Rings (2020)

Cribbing (also known as crib biting or windsucking) is one of many repetitive behaviors known as stereotypies which are sometimes demonstrated by horses. A variety of devices have been utilized to prevent horses from cribbing, including hog rings.
The AAEP opposes the use of hog rings placed around the maxillary incisors to prevent cribbing in horses. These devices are detrimental to the welfare of the horse due to the potential to cause persistent pain, damage to the gingiva, periodontal disease and abrasive wear to adjacent teeth. Hog rings should not be used as an anti-cribbing device.
