Why people need to cut Corgi's tail?

Corgis often have their tails docked for historical reasons, primarily related to their herding background. Docking was believed to prevent injuries while working with livestock and to maintain a specific breed standard. However, tail docking is increasingly viewed as unnecessary and unethical, leading to changing regulations in many countries that prohibit the practice. Many advocates now emphasize the importance of allowing Corgis to retain their natural tails for health and welfare reasons.
