Greater Swiss Mountain Dog Breed Standard Working Group    General Appearance The Greater Swiss Mountain Dog is a Draft and Drover breed and should structurally appear as such. It is a striking, tri-colored, large, powerful, confident dog of sturdy appearance. It is a heavy boned and well muscled dog which, in spite of its size and weight, is agile enough to perform the all-purpose farm duties of the mountainous regions of its origin.  Size, Proportion and Substance Height at the highest point of the shoulder is ideally: Dogs: 25.5 to 28.5 inches. Bitches 23.5 to 27 inches. Body length to height is approximately a 10 to 9 proportion, thus appearing slightly longer than tall. It is a heavy boned and well muscled dog of sturdy appearance.  Coat Topcoat is dense, approximately 1-1/4 to 2 inches in length. Undercoat must be present and may be thick and sometimes showing, almost always present at neck but may be present throughout. Color of undercoat ranges from the preferred dark gray to light gray to tawny. Total absence of undercoat is undesirable and should be penalized.  Color The topcoat is black. The markings are rich rust and white. Symmetry of markings is desired. On the head, rust typically appears over each eye, on each cheek and on the underside of the ears. On the body, rust appears on both sides of the forechest, on all four legs and underneath the tail. White markings appear typically on the head (blaze) and muzzle. The blaze may vary in length and width. It may be a very thin stripe or wider band. The blaze may extend just barely to the stop or may extend over the top of the skull and may meet with white patch or collar on the neck. Typically, white appears on the chest, running unbroken from the throat to the chest, as well as on all four feet and on the tip of the tail. White patches or collar on the neck is acceptable. Any color other than the "Black, Red and White" tri-colored dog described above, such as "Blue/Charcoal, Red and White" or "Red and White" is considered a disqualification. When evaluating the Greater Swiss Mountain Dog, markings and other cosmetic factors should be considered of lesser importance than other aspects of type which directly affect working ability.  Temperament Bold, faithful, willing worker. Alert and vigilant. Shyness or aggressiveness shall be severely penalized.  Summary The foregoing is the description of the ideal Greater Swiss Mountain Dog. Defects of both structure and temperament are to be judged more severely than mere lack of elegance because they reduce the animal's capacity to work. Any fault that detracts from the above described working dog should be penalized to the extent of the deviation.
