The Austrian Pinscher (Österreichischer Pinscher, FCI No. 64) is a medium-sized breed of pinscher-type dog from Austria, where dogs of the type were originally farm dogs, keeping barns free of rats and acting as home guards, livestock guardians, and drovers.
 The name originally given to the breed in 1928 was the "Österreichischer Kurzhaarpinscher" ("Austrian Shorthaired Pinscher") to differentiate it from similarly named breeds, but today in its country of origin the breed is officially called the Österreichischer Pinscher, or Austrian Pinscher in English.
The Harlequin Pinscher is a type of Miniature Pinscher, which is a toy-sized dog.
 It originated in Germany and was created by crossing traditional Miniature Pinschers with various toy-sized short-haired terriers.
 It originated in Germany where it was used to kill rats and mice.
 It is known by several different names including the Harlequin Pinscher, Spotted Pinscher, Merle Pinscher, Harlequin Miniature Pinscher and the Harlequin Min Pin.
 It is believed that the Harlequin Pinscher was created in Germany some time during the late 18th century.
 They were likely the result of crosses between traditional Miniature Pinschers and Toy Fox Terriers or Rat Terriers.
 While Harlequin and other Min Pins were mainly used for ratting throughout history, they were also cherished pets.
 Harlequin Pinschers nearly became extinct following World War II; however, a group of enthusiasts worked together to revive the breed by collecting worthy specimens to breed.
 Today, although the Harlequin Pinscher is rather rare, select Min Pin breeders are working hard to establish it as a pure-breed that is eligible for registration.
The Lucas Terrier is a small breed of dog of the terrier type which originated in England in the late 1940s.

 It is traditionally called the "King of Terriers" because it is the largest of the terrier breeds.
 The Airedale was bred from the Old English Black and Tan Terrier (now extinct), the Bull Terrier, the Otterhound and probably some other Terrier breeds, originally to serve as an all around working farm dog.
 In Britain this breed has also been used as a war dog, guide dog and police dog.
 In the United States, this breed has been used to hunt big game, upland birds, and water fowl, and serve in many other working capacities.

The German Pinscher (original name Deutscher Pinscher, FCI No. 184) is a medium-sized breed of dog, a Pinscher type that originated in Germany.
 The breed is included in the origins of the Dobermann, the Rottweiler, the Miniature Pinscher, the Affenpinscher, the Standard Schnauzer (and, by extension, the Miniature Schnauzer and Giant Schnauzer).
 The breed is rising in numbers in the U.S., mainly due to their full acceptance to AKC in 2003.
 In Australia, the breed is established with a rise in popularity becoming evident.
The Giant Schnauzer is a working breed of dog developed in the 17th century in Germany.
 It is the largest of the three breeds of Schnauzerthe other two breeds being the Standard Schnauzer and the Miniature Schnauzer.
 Numerous breeds were used in its development, including the black Great Dane, the Bouvier des Flandres, and the German Pinscher.
 Originally bred to assist on farms by driving livestock to market and guarding the farmer's property, the breed eventually moved into the city, where it worked guarding breweries, butchers' shops, stockyards and factories.
 It was unknown outside of Bavaria until it became popular as a military dog during World War I and World War II.
The Teddy Roosevelt Terrier is a small to medium-sized American hunting terrier.
 Lower-set with shorter legs, more muscular, and heavier bone density than its cousin the American Rat Terrier.
 There is much diversity in the history of the Teddy Roosevelt Terrier breed and it shares a common early history with the American Rat Terrier, Fox Paulistinha and Tenterfield Terrier.
 It is said the Rat Terrier background stems from the terriers or other dogs that were brought over by early English and other working class immigrants.
 Since the breed was a farm, hunting and utility dog there was little to no planned breeding other than breeding dogs with agreeable traits to each other in order to produce the desired work ethic in the dog.
 It is assumed that the Feist (dog), Bull Terrier, Smooth Fox Terrier, Manchester Terrier, Whippet, Italian Greyhound, the now extinct English White Terrier, Turnspit dog and or Wry Legged Terrier all share in the Teddy Roosevelt Terrier's ancestry.
 These early Ratting Terriers were then most likely bred to the Beagle or Beagle cross bred dogs (for increased scenting ability) and other dogs.
 Maximizing the influences from these various breeds provides the modern Teddy Roosevelt Terrier with a keen sense of awareness and prey drive, an acute sense of smell and a very high intellect.
 Although they tend to be aloof with strangers they are devoted companion dogs with a strong desire to please and be near their owners side at all times.
The Sporting Lucas Terrier is a small breed of dog of the terrier type.
 The breed is named for Jocelyn Lucas.
