The Cumberland sheepdog is an extinct dog breed related to the border collie and other old working collie types.  It is claimed to be one of the ancestors of the Australian shepherd and in the early part of the 20th century some Cumberland sheepdogs were being referred to as border collies and may have been absorbed into the latter breed. The German Shepherd (German: Deutscher Schäferhund , ] ) is a breed of medium to large-sized working dog that originated in Germany.  The breed's officially recognized name is German Shepherd Dog in the English language (sometimes abbreviated as "GSD").  The breed is also known as the Alsatian in Britain and Ireland.  The German Shepherd is a relatively new breed of dog, with their origin dating to 1899.  As part of the Herding Group, German Shepherds are working dogs developed originally for herding sheep.

The German Shepherd is the second-most registered breed by the American Kennel Club and fourth-most registered breed by The Kennel Club in the United Kingdom. Sheepdog Glory is a novel written by Roy Saunders in 1956.  It is a biography of Toss, a border collie herding dog owned by Saunders.

The Shetland Sheepdog, also known as the Sheltie, is a breed of herding dog.  The original name of this breed was Shetland Collie, but this caused controversy among the Rough Collie breeders at the time, so the breed's name was formally changed to Shetland Sheepdog.  This small dog is intelligent, vocal, excitable, energetic and willing to please and work hard.  The breed was formally recognized by The Kennel Club in 1909. The Himalayan Sheepdog, also referred to as the Bhote Kukur or Bhotia, is a livestock guardian dog that originated from Nepal.
