Like the other Sennenhund, the Bernese mountain dog is a large, heavy dog with a distinctive tri-colored coat, black with white chest and rust colored markings above eyes, sides of mouth, front of legs, andount around the white chest. However, it is the only breed of Sennenhund dogs with a long coat. The ideal of a perfectly marked individual gives the impression of a white horseshoe shape around the nose, which is always black. There is 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. The AKC breed standard lists, as disqualifications, blue eye color, and any ground color other than black.
