Sheep shearing is a welfare necessity for domesticated breeds that cannot shed their wool, but shearing practices vary widely, with skilled and humane shearing contrasting with rough handling that causes injury and distress.
Shearing is a genuine welfare necessity that, done well, prevents the suffering of wool overgrowth but done badly causes acute welfare harm. Rough handling during shearing including excessive force, inappropriate restraint positions, and careless use of handpieces causes pain, injury, and significant fear responses. Shearing speed competitions that prioritize throughput over care have been documented causing welfare harm. The welfare outcome of shearing depends almost entirely on the skill, care, and animal welfare orientation of the shearer, making shearer training and quality standards a critical welfare issue.
