The American Hairless Terrier (AHT) derived from the Rat Terrier breed was developed in the United States in the early 1970s. These alert and curious dogs are usually hairless but can also have a coat. Like most terriers, its ancestors were bred to hunt rats and other vermin. Today, the AHT is a lively, intelligent and friendly companion who loves to be indoors with its owner. The American Hairless Terrier is a smoothly muscled, active, small-to-medium size terrier whose trainability makes it a perfect choice for such dog sports as Obedience and Agility. The American hairless Terrier will be shown in the Terrier Group.
