The Boston Terrier is a small, dark-brindle-and-white or black-and-white dog with a smooth, unwrinkled broad head that looks somewhat like a Boxer's. The muzzle is short, topped with a full black nose. The body is slender with well-defined lines, with a build more like a terrier than like a bulldog. The expressive, wide-set eyes are very large, dark and rounded. The ears are small and erect, and may be cropped or uncropped. The tail is short and either straight or screw, carried low. The short coat does not shed.
The Boston Terrier is an American breed developed in Boston from crosses involving English Bulldogs, French Bulldogs, and some terrier breeds. The breed became popular in Boston, where it was initially called the American Bull Terrier. The name was soon changed to Boston Terrier, and the AKC recognized the breed in 1893. Today's Boston Terrier is primarily a house pet and companion dog.
