Ear cropping and tail docking are painful cosmetic procedures performed on dogs for breed standards — procedures banned in many countries but still widely practiced in the US and others.
Cosmetic ear cropping and tail docking cause unnecessary pain and carry risks of infection, chronic pain, and behavioral impact. The argument that neonatal tail docking is painless because puppies are too young to feel pain is refuted by research showing stress hormone elevation, behavioral distress responses, and functional nociceptive pathways in newborn dogs. Ear cropping, typically performed at 8-12 weeks, requires general anesthesia and involves weeks of painful healing and ear manipulation. Neither procedure provides any health benefit to the dog; the sole justification is conformity with breed standards that themselves originated in working dog practices now irrelevant to companion animals. Countries that have banned these procedures have seen no adverse effects on affected breeds.
