Where are Entlebuchers from?
Entlebuchers are originally from the Entlebuch region in Switzerland. An excellent herder, this breed of Swiss mountain dog was used as an all-purpose farm dog for centuries. By the early 1900s, Entlebuchers (or Entles, for short) were nearly extinct due to breeding with German Shepherds and other imported breeds until a professor named Albert Heim revived the breed.
