The Boston Terrier is a breed of dog originating in the United States of America. They are typically small, compactly built, well proportioned dogs with erect ears, short tails, and a short muzzle that should be free of wrinkles. They usually have a square sort of face. The breed is known for its gentle, alert, expressive, and well-mannered. Many still retain the spunky attitude of the typical terrier. Having been bred as a companion dog, they enjoy being around people, and, if properly socialized, get along well with children, the elderly, other canines, and non-canine pets. Some Boston Terriers are very cuddly, while others are more independent.
