The Entlebucher Mountain Dog, also known as the Entlebuch Mountain Dog, Entlebucher Sennenhund, Entlebucher Cattle Dog, Entlebuch Cattle Dog or simply the Entlebucher, originated in the Entlebuch valley of Switzerland. It is the smallest of the four tri-colored Swiss Mountain dogs, which include the Bernese Mountain Dog, the Greater Swiss Mountain Dog and the Appenzeller Sennenhunde. The Entlebucher is popular in its native country but is still relatively rare in the rest of the world. This is a smart, sturdy dog that has enough power to control large animals yet enough agility to move quickly. Entlebuchers are personable and easy to train, although they are strong-willed and can be challenging for novice dog owners. Their stamina, floating gait and eagerness to please make them well-suited for all sorts of outdoor activities. They love to pull carts and excel at herding. Entlebuchers are faithful and devoted to their owners, but tend to be somewhat reserved and suspicious of strangers.
