The Bernese Mountain Dog (German: "Berner Sennenhund" ) is a large-sized breed of dog, one of the four breeds of Sennenhund-type dogs from the Swiss Alps.

 "Berner" (or "Bernese" in English) refers to the area of the breed’s origin, in the canton of Bern.
 This mountain dog was originally kept as a general farm dog.
 Large Sennenhunde in the past were also used as draft animals, pulling carts.
