This document discusses tail docking in dogs. Tail docking is defined as removing part of a healthy tail from a healthy puppy, usually within the first 5 days of life. Traditionally, it was done in certain breeds to prevent tail injuries while working. However, it is now banned in some places due to animal welfare concerns as it is done without anesthesia. The document describes the common docking techniques using scissors or ligatures and recommendations for aftercare to prevent infection.
