Traditionally, the Yorkshire Terrier's tail is docked to a medium length.
  Opposition to this practice began very early in the history of the breed; Hugh Dalziel, writing about Yorkshire Terriers in 1878, declared that "There is no reason for mutilating pet dogs, and perfect ears and tails should be bred, not clipped into shape with scissors."
AKC and Canadian Kennel Club still require the Yorkie's tail be docked in order to compete at its events.
The majority of the rest of the world has adopted a "no docking/no cropping" rule.
Often, a Yorkshire Terrier's dewclaws, if any, are removed in the first few days of life, another controversial practice.
