UKC says practically the same thing. They , too, follow the club standard . COPIED AND PASTED:

The tail is customarily docked to a medium length. The tail set is level with the topline, with the tail carried slightly higher than the level of the back. If undocked, the tail is as straight as possible, well covered with hair, and carried a little above the level of the topline. On an undocked tail the hair will be a darker blue than on the rest of the body, especially at the tip.
