Tail Docked. At maturity it should measure approximately 6 inches with a tendency to be light rather than heavy and should be carried in a manner expressing confidence and sound temperament. A non-docked tail shall be penalized.
Long Hair Weimaraner Tails: There is a longhair variety of weimaraner that many people find attractive. This variety is, in fact, recognized by and shown in all the major kennel clubs of the world except those in the United States. Although longhair weimaraners are in the minority, they are regularly born into shorthair litters. The long coat is no drawback in any of the many levels of competition or sport for which the versatile weimaraner is suitable. Unlike the shorthair weimaraner, which has its tail docked in puppyhood so that it is approximately 6 inches long at maturity, the longhair weimaraner generally is not subject to tail docking. If the longhair's tail is docked at all, only a vertebrae or two are removed. Taken verbatim from: http://www.petpublishing.com/dogken/breeds/weimar.shtml

As you have read above, in the United States the breed standard is to dock a Weimaraner's tail. Ideally the tail should be about 6" long when the Weim reaches full growth. Many places throughout the world have banned tail docking and ear cropping. For this reason, you now see European Weimaraners with a full length tail. When we receive inquiries from Europe they are for what they call a "Complete Weim." They mean they want an undocked tail and the dew claws left intact. Most Americans who do decide on an undocked tail want the dew claws removed.
Our Policy at OwyheeStar on Undocked Tails:
We are willing to raise a puppy with an undocked tail. Since the breed standard in America is for a docked tail, we require a larger (non-refundable) Puppy Deposit. This is due to the fact that in general the pup is worth considerably less in the American market at this time.
We are also severely limited on choices because tail docking occurs at 3 days of age. Therefore the puppy is picked by random guess based on the projected breeding goals for that litter. By the time the puppy is 8 weeks old the tail is sizeable and tail docking would be expensive as well as painful.
Soon (late 2008) we will be raising a pup with an undocked tail for a special family. We hope to follow this experience in pictures for those of you curious or interested in knowing more about undocked tails.
