Like the other Sennenhunds, the Bernese Mountain Dog is a large, heavy dog with a distinctive tricolored coat, black with white chest and rust colored markings above eyes, sides of mouth, front of legs, and a small amount around the white chest. An ideal of a perfectly-marked individual gives the impression of a white horse shoe shape around the nose and a white "Swiss cross" on the chest, when viewed from the front. A Swiss Kiss is a white mark located typically behind the neck, but may be a part of the neck. A full ring would not meet type standard. Both males and females have a broad head with smallish, v-shaped drooping ears.
he Bernese Mountain Dog, like every dog, is descended from the wolf. Historically, in some locales at least, the breed was called a Dürrbachhunde. The breed was used as an all purpose farm dog, for guarding property and to drive dairy cattle long distances from the farm to the alpine pastures. The type was originally called the Dürrbächler, for a small town (Dürrbach) where the large dogs were especially frequent. In the early 1900s, fanciers exhibited the few examples of the large dogs at shows in Berne, and in 1907 a few breeders from the Burgdorf region founded the first breed club, the "Schweizerische Dürrbach-Klub", and wrote the first Standard which defined the dogs as a separate breed. By 1910, there were already 107 registered members of the breed. There is a photo of a working Bernese Mountain Dog, dated 1905 at the Fumee Fall rest area in Quinnesec, MI.
