The King Shepherd is a dog breed developed from crossing German Shepherd Dog with Shiloh Shepherd and long-coated European lines of German Shepherd along with the Great Pyrenees in the 1990s.
The American Hairless Terrier is a rare breed of dog that was derived as a variant of Rat Terrier.
 As of January 1, 2004, the United Kennel Club deemed the AHT a separate terrier breed, granting it full UKC recognition.
 An intelligent, social and energetic working breed, the American Hairless Terrier is often listed as a potential good breed choice for allergy sufferers.
Rare breed (dog) is any breed of dog that is small in number and is used to refer to both old established breeds such as the Stabyhoun and Glen of Imaal Terrier or newer creations.
 Since dogs have greater genetic variability than other domesticated animals the number of possible breeds is vast with new crosses constantly occurring, from these both selected and random crosses may come new breeds should offspring reliably breed true to type.
 New breeds from the wild such as the Carolina Dog are quite rare compared to attempts at breed creation from man as found in the American Hairless Terrier which sought to exploit a mutation.
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 Chiribaya Dog (Spanish: "perro Chiribaya" ) or Peruvian shepherd dog ("perro pastor Peruano ") was a pre-Columbian breed of dog from the southwest of Peru, identified by the 42 mummies discovered by anthropologist Sonia Guillén Oneglio in the Ilo District, Moquegua Region, on the south coast of Peru.
 It has been established that it was a llama herding dog.
 The dogs were not only an important part of the social structure of the ancient Peruvians, but they received special treatment after death as well.
 The dog variety has been referred to in various Spanish-language documentaries under different terms, such as "el perro pastor Chribaya" ('the Chiribaya shepherd dog') and "pastor Peruano " ('Peruvian shepherd'), though the ancient Peruvians did not keep sheep.
 Its original name is unknown.
 (It has been referred to more ambiguously by the term "perro Peruano " or "perro del Perú " ('Peruvian dog', 'dog of Peru'), but this has also been applied to an extant but ancient hairless variety, referred to in more detail as "perro sin pelo del Perú", 'hairless dog of Peru', or the Peruvian hairless dog, a favorite in South American dog shows.)
The Airedale Terrier (often shortened to "Airedale"), also called Bingley Terrier and Waterside Terrier, is a dog breed of the terrier type that originated in the valley ("dale") of the River Aire, in the West Riding of Yorkshire, England.
 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.
Fox Terriers are two different breeds of the terrier dog type: the Smooth Fox Terrier and the Wire Fox Terrier.
 Both of these breeds originated in the 19th century from a handful of dogs who are descended from earlier varieties of British terriers, and are related to other modern white terrier breeds.
 In addition, a number of breeds have diverged from these two main types of fox terrier and have been recognised separately, including the Jack Russell Terrier, Miniature Fox Terrier and Rat Terrier.
 The Wire and Smooth Fox Terriers share similar characteristics, the main differences being in the coat and markings.
 They have been successful in conformation shows, more prominently in America than their homeland.
A Feist is a small hunting dog, descended from the terriers brought over to the United States by English miners and other working class immigrants.
 These terriers probably included crosses between the Smooth Fox Terrier, the Manchester Terrier and the now extinct English White Terrier.
 These dogs were used as ratters, and gambling on their prowess in killing rats was a favorite hobby of their owners.
 Some of these dogs have been crossed with Whippets or Italian Greyhounds (for speed) and Beagles (for hunting ability) - extending the family to include a larger variety of purpose than the original ratter, or Rat Terrier.
The Rat Terrier is an American dog breed with a background as a farm dog and hunting companion.
 Traditionally more of a type than a breed, they share much ancestry with the small hunting dogs known as feists. Common throughout family farms in the 1920s and 1930s, they are now recognized by the United and American Kennel Clubs and are considered a rare breed.
 Today's Rat Terrier is an intelligent and active small dog that is kept both for pest control and as a family pet.
The Shiloh Shepherd is a new dog breed that is still under development.
 They are not recognized by any major kennel club, but may be shown in some rare breed organizations.
