The Entlebucher Mountain Dog is one among the four Swiss dog breeds (Sennenhund) which include the Greater Swiss Mountain Dog, Bernese Mountain Dog, and Appenzeller Mountain Dog. However, the Entlebucher is smaller and considered to be quicker. The name Entlebucher was derived after a region in Switzerland where the breed was first bred to work.
Like the other Swiss dogs, the Entlebucher Mountain Dog is believed to have descended from the large ancient Mollosers that the Romans brought to Switzerland in the first century BC when they crossed the Alps. At that time, there was little distinction between the Appenzeller and the Entlebucher, until the latter was defined as a separate breed in 1889.
In 1913, Albert Heim advocated to increase the population of the Sennenhund breeds, and the dog breeds were entered into the Swiss Kennel Club book, including the Entlebucher. However, when World War I broke out, the Entlebucher and other Swiss dog breeds dwindled in numbers. It was not until 1926 that sixteen Sennenhund dogs were found, and the breed was slowly restored. However, until this day Entlebucher dog breeds are still rare in the UK.
