Horse stable vices including cribbing, wood chewing, and box walking develop in response to environmental deficiencies and respond to management changes rather than behavioral suppression.
Horse stable vice welfare requires understanding that these behaviors are symptoms of environmental inadequacy, not character defects. The same horse that cribs in an isolated stable often shows no stereotypy in appropriate pasture management. Wood chewing driven by fiber deficiency resolves with increased hay provision. Box walking resolves with increased turnout and social contact. The welfare-appropriate response to developing stable vices is environmental audit: what movement, forage, social contact, or stimulation is missing? Anti-vice devices that suppress behavior without addressing deficits cause frustration and may redirect to other behaviors while preventing the owner from recognizing the underlying welfare problem.
