Bernese Mountain

Dog

The Bernese Mountain Dog, called in German the Berner Sennenhund, is a large breed of dog, one of the four breeds of Sennenhund-type dogs from the Swiss Alps. The name Sennenhund is derived from the German "Senne" (alpine pasture) and "hund" (dog), as they accompanied the alpine herders and dairymen called Senn. Berner (or Bernese in English) refers to the area of the breed's origin, in the Canton of Bern in Switzerland.
