In November 2009 and January 1, 2010, the United Kennel Club (UKC) removed the disqualification from both Blue and Longhair Weimaraners. A black coat remains an automatic disqualification, though a small white marking in the chest area only is permitted. Dogs with blue coats are disqualified from conformation/show competition, but are recognized as purebred Weimaraners by the AKC. There is another incidental variety, described as having the 'mark of the hound', where the dog is the usual grey colour but with faint tan markings (similar to Doberman Pinschers). Weimaraners can have several unique physical characteristics such as small lobes on the inside of the ear, known as 'Harrasburg Horns', and 'Grafmar's Caps', very light gray patches between the ears.A long-haired variety is recognized by most kennel clubs around the world except the American Kennel Club. The long-haired Weimaraner has a silky coat with an undocked, feathered tail. The gene is recessive, so breeding will produce some long-haired puppies only if both parents carry the trait.
