The Bernese Mountain Dog is a large dog breed, one of the four breeds of Sennenhund-type dogs from Bern, Switzerland and the Swiss Alps. These dogs have roots in the Roman mastiffs. The name Sennenhund is derived from the German Senne and Hund, as they accompanied the alpine herders and dairymen called Senn. Big, powerful, and built for hard work, the Bernese Mountain Dog is also strikingly beautiful and blessed with a sweet, affectionate nature. Berners are generally placid but are always up for a romp with the owner, whom they live to please. The Bernese Mountain Dog is a large, sturdy worker who can stand over 27 inches at the shoulder. The thick, silky, and moderately long coat is tricolored: jet black, clear white, and rust. The distinctive markings on the coat and face are breed hallmarks and, combined with the intelligent gleam in the dark eyes, add to the Berner’s aura of majestic nobility. A hardy dog who thrives in cold weather, the Berner’s brain and brawn helped him multitask on the farms and pastures of Switzerland. Berners get along with the entire family and are particularly gentle with children, but they will often become more attached to one lucky human. Berners are imposing but not threatening, and they maintain an aloof dignity with strangers.

Head – Expression is intelligent, animated and gentle. The eyes are dark brown and slightly oval in shape with close-fitting eyelids. Inverted or everted eyelids are serious faults. Blue eye color is a disqualification. The ears are medium sized, set high, triangular in shape, gently rounded at the tip, and hang close to the head when in repose. When the Bernese Mountain Dog is alert, the ears are brought forward and raised at the base; the top of the ear is level with the top of the skull.

The skull is flat on top and broad, with a slight furrow and a well-defined, but not exaggerated stop. The  muzzle is strong and straight. The nose is always black. The lips are clean and, as the Bernese Mountain Dog is a dry-mouthed breed, the flews are only slightly developed. The teeth meet in a scissors bite. An overshot or undershot bite is a serious fault.
