Stereotypic behaviours such as crib-biting, weaving, and box-walking in horses are signs of chronic frustration and inadequate environments, not wilful bad habits.
Stereotypic behaviours are not "bad habits" or character flaws — they are welfare indicators signalling that a horse's fundamental needs are not being met. A horse that weaves or cribs is coping with a poor environment, not misbehaving. Using physical restraints to prevent these behaviours while maintaining the same housing conditions is ethically questionable — it removes the coping mechanism without addressing the underlying problem. Welfare-centred management focuses on prevention through adequate turnout, roughage, and social contact, and management through environmental improvement rather than restraint.
