Swiss mountain dog

While the two larger ones share a heavy build and a calm temperament, the two smaller ones are more agile.

The name Sennenhund refers to people called Senn or Senner, Swiss Alpine herdsmen and dairymen, and does not translate as "mountain" or "cattle".

In the United States, the Bernese Mountain Dog has become somewhat popular, while the other three breeds are promoted as rare to those seeking unique pets.

The guarding function was especially necessary in earlier times, when wolves and other large predators threatened livestock and people.
