The American Hairless Terrier was independently developed when a hairless pup was produced in a litter of normal Rat Terriers. The owners of this pup, Edwin and Willie Scott attempted to breed her to other Rat terriers but were not successful in having another hairless pup until years later. Then they had a litter with one male and one female hairless puppy.
From that point on they worked with a veterinarian and a geneticist to develop the breed until it was accepted as a separate breed from the Rat Terrier in 2004 and accepted into the AKC in 2016.
