aking from th KC breed standard:
Tail
Well furred, of round, fox brush shape set on just below level of topline and usually carried over back in graceful sickle curve when dog at attention. When carried up, tail should not curl too tightly, nor should it curl to either side of body, or snap flat against back. Hair on tail of medium length and approximately same length all round. A trailing tail is normal for dog when working or in repose.
Thats how the tail should be :)
