Rare breed (dog) : ウィキペディア英語版 | Rare breed (dog)
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. == Establishment of breeds == Modern dog breeds have documented descent from known foundation stock, and new breeds are often derived from older, established modern breeds. New documentation of a long established dog type, sometimes with a variation on an older name, also creates a new modern breed. The newly documented breed is then referred to as a ''rare breed'' as long as the number of dogs of the breed remain small.
