Routine tail docking of piglets without pain relief remains common in many countries despite being a welfare compromise and the EU having guidelines against routine use.
Tail docking without anesthesia causes acute pain and potential chronic pain at the wound site. It is a symptom-control measure that does not address the root causes of tail biting - namely, inadequate enrichment and poor housing conditions. Sweden and Finland have essentially eliminated tail docking through mandatory provision of enrichment materials, demonstrating that alternatives work. The EU has repeatedly called for a phase-out of routine docking.
