The Bernese Mountain Dog is slightly longer than tall, though it appears square. It is a sturdy, large, hardy dog capable of both draft and droving work. This requires a combination of strength, speed and agility. Its natural working gait is a slow trot, but with good reach and drive. Its thick coat is moderately long, and slightly wavy or straight, providing insulation from the cold. Its expression is gentle, and its coloring is striking.

The Bernese mountain dog is an easygoing, calm family companion (that is, after it leaves its adolescent stage). It is sensitive, loyal and extremely devoted. It is gentle with children and often reserved with strangers. It generally gets along well with other dogs and pets.
