The American Hairless Terrier is an energetic, alert dog whose curiosity and intelligence make him easy to train. The ancestors of this breed were bred to hunt. The lack of coat makes the hairless variety unsuited for hunting, but both varieties still have a strong hunting instinct and the coated dogs are fearless, tenacious hunters with seemingly unlimited energy. The American Hairless Terrier is an exceptionally friendly companion, getting along well with children, other dogs, and even cats. American Hairless Terriers enjoy human companionship immensely and will enthusiastically share any activity with their owners. The hairless dogs require protection from the sun and winter cold weather. American Hairless Terriers should not be sparred during conformation judging.
