Tail docking is performed routinely in sheep and pigs to reduce certain health risks, but causes significant acute pain and raises important questions about whether the underlying management problems should be addressed instead.
Both sheep and pig tail docking cause acute pain through tissue damage to a sensitive body part. While there are genuine production arguments for docking in certain contexts, these arguments reflect underlying management failures rather than inherent necessities. Pigs tail-bite when understimulated, overcrowded, and poorly fed — conditions that are common in intensive systems. Addressing enrichment, space, and nutrition can substantially reduce tail-biting without the need for a painful mutilation performed on every animal.
