The Scotch Collie is a landrace breed of dog which originated from the highland regions of Scotland.
 The breed consisted of both the long-haired (now known as Rough) Collie and the short-haired (now known as Smooth) Collie.
 It is generally believed to have descended from a variety of ancient herding dogs, some dating back to the Roman occupation, which may have included Roman Cattle Dogs, Native Celtic Dogs and Viking Herding Spitzes.
 Other ancestors include the Gordon and Irish Setters.
The collie is a distinctive type of herding dog, including many related landraces and standardised breeds.
 The type originated in Scotland and Northern England.
 The collie is a medium-sized, fairly lightly built dog, with a pointed snout.
 Many types have a distinctive white pattern over the shoulders.
 Collies are very active and agile, and most types of collies have a very strong herding instinct.
 Collie breeds have spread through many parts of the world (especially Australia and North America) and have diversified into many varieties, sometimes with mixture from other dog types.
 Some collie breeds have remained as working dogs, used for herding cattle, sheep and other livestock, while others are kept as pets, show dogs or for dog sports, in which they display great agility, stamina and trainability.
 While the AKC has a breed they call "Collie", in fact collie dogs are a distinctive type of herding dog including many related landraces and formal breeds.
 There are usually major distinctions between show dogs and those bred for herding trials or dog sports.
 They typically display great agility, stamina and trainability and more importantly sagacity.
The Pembroke Welsh Corgi ( ; Welsh for "dwarf dog") is a cattle herding dog breed which originated in Pembrokeshire, Wales.
 It is one of two breeds known as a Welsh Corgi.
 The other is the Cardigan Welsh Corgi, and both descend from the line that is the northern spitz-type dog (examples include that of the Siberian Husky).
 Another theory is that Pembrokes are descended from the Swedish Vallhunds, which were crossed with the local Welsh herding dogs.
 The Pembroke Welsh Corgi is the younger of the two Corgi breeds and is a separate and distinct breed from the Cardigan.
 The corgi is one of the smallest dogs in the Herding Group.
 Pembroke Welsh Corgis are famed for being the preferred breed of Queen Elizabeth II, who has owned more than 30 during her reign.
 These dogs have been favored by British royalty for more than seventy years, but among British Commoners, have recently fallen into decline in terms of popularity and demand.
A herding dog, also known as a stock dog or working dog, is a type of pastoral dog that either has been trained in herding or belongs to breeds developed for herding.
 Their ability to be trained to act on the sound of a whistle or word of command is renowned throughout the world.
 Collies are recommended as herding dogs.
The Koolie (also known as the Australian Koolie or by the misnomer German Coolie) is an Australian dog breed.
 The Koolie is a working or herding dog which has existed in Australia since the early 19th century when it was bred from imported British working dogs.
 Robert Kaleski, in an article on Cattle Dogs in the August 1903 issue of the Agricultural Gazette of New South Wales, describes the "Welsh heeler or merle, erroneously known as the German collie," as a "blue-gray dog about the size and build of a smooth-haired collie, generally with wall eyes."
 The British background predominated in the dogs that came to be associated with the "German collie" name.
Dogs with Jobs is a Canadian documentary television series about working dogs and show dogs. Each half-hour episode consists of two to three segments on individual dogs from around the world.
 The family-friendly series has featured service dogs, search and rescue dogs, police dogs, herding dogs, and others.
 Segments show footage of dogs on the job, and also include stories of their rescue, training, and relationships with their owners and handlers.
The Stephens Cur (a.k.a. Stephens' Stock Cur), is a scent hound that belongs to the Cur dog breed.
 They were originally bred by the Stephens family in southeastern Kentucky.
 The dogs known as "Little black dog" were bred by generations of that family for over a century.
 In 1970, they were recognized as separate and distinct breed of Cur.
 The dog is mostly black with white markings, but more than a third white is not permissible.
 It is good for hunting raccoon and squirrel, but can also be used to bay wild boar.
 They are registered with the United Kennel Club
The old German herding dogs (German: "altdeutsche Hütehunde" ), including old German sheep-dogs or old German shepherd dogs (altdeutsche Schäferhunde ) are a group of traditional types of working, herding dogs from Germany.
 They are landraces consisting of working strains of dog, and some of them are the types from which the modern German Shepherd Dog was developed as a standardised breed.
 The landraces are not recognised by the Fédération Cynologique Internationale but some have their own standards, which are for working ability not appearance traits.
Herding Group is the name of a breed group of dogs, used by kennel clubs to classify a defined collection of dog breeds.
 It does not refer to one particular type of dog.
 How the "Herding Group" is defined varies among kennel clubs, and different kennel clubs may not include the same breeds in their "Herding Group".
 Some kennel clubs do not use the term "Herding Group".
 The international kennel club association, the Fédération Cynologique Internationale, does not have a "Herding Group", and includes most pastoral dogs in Group 1 "Sheepdogs and Cattle Dogs (except Swiss Cattle Dogs)" and Group 2 "Pinscher and Schnauzer - Molossoid Breeds - Swiss Mountain and Cattle Dogs".
The Smooth Collie is a breed of dog developed originally for herding.
 It is a short-coated version of the Rough Collie of Lassie fame.
 Some breed organisations consider the smooth-coat and rough-coat dogs to be variations of the same breed.
