Bernese Mountain Dog

The Bernese Mountain Dog, German: Berner Sennenhund or Dürrbächler, is a large dog breed originating from the canton of Bern, Switzerland and the Swiss Alps. It is one of four Sennenhund-type breeds, with ancestral roots in Roman mastiffs. The name Berner refers to the breed's area of origin in the canton of Bern, and Sennenhund is derived from the German Senne and Hund ("hound/dog"), as they accompanied the alpine herders and dairymen called Senne. Historically used as a general farm dog, the large Sennenhunde also pulled carts as draft animals. The breed was formally recognized in 1912.
