question: What is a rare breed of dog that was derived as a variant of Rat Terrier, Shiloh Shepherd dog or American Hairless Terrier ?
answer: American Hairless Terrier
context: Title: Rare breed (dog)
  Passage: 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.
  Title: American Hairless Terrier
  Passage: 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.
  Title: Fox Terrier
  Passage: 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.
  Title: Chiribaya Dog
  Passage: 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.)
  Title: Shiloh Shepherd dog
  Passage: 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.
