The Boston Terrier is a breed of dog originating in the United States of America. This "American Gentleman" was accepted in 1893 by the American Kennel Club as a non-sporting breed. Color and markings are important when distinguishing this breed to the AKC standard. They should be either black, brindle or seal with white markings. Bostons are small and compact with a short tail and erect ears. The AKC says they are highly intelligent and very easily trained. They are friendly and can be stubborn at times. The average life span of a Boston is around 11 to 13 years, though some can live well into their teens.
The Boston Terrier breed originated around 1870, when Robert C. Hooper of Boston, purchased a dog Judge from Edward Burnett known later as Hooper's Judge, who was of a Bull and Terrier type lineage. Hooper's Judge is either directly related to the original Bull and Terrier breeds of the 18th and early 19th centuries, or Judge is the result of modern English Bulldogs being crossed into terriers created in the 1860s for show purposes, like the White English Terrier.
Judge weighed over 27.5 pounds (13.5 kilos). The offspring interbred with one or more French Bulldogs, providing the foundation for the Boston Terrier. Bred down in size from fighting dogs of the Bull and Terrier types, the Boston Terrier originally weighed up to 44 pounds (20 kg.) (Olde Boston Bulldogge). The breed was first shown in Boston in 1870. By 1889 the breed had become sufficiently popular in Boston that fanciers formed the American Bull Terrier Club, the breed's nickname, "roundheads". Shortly after, at the suggestion of James Watson (a noted writer and authority), the club changed its name to the Boston Terrier Club and in 1893 it was admitted to membership in the American Kennel Club, thus making it the first US breed to be recognized. It is one of a small number of breeds to have originated in the United States. The Boston Terrier was the first non-sporting dog bred in the US.
In the early years, the color and markings were not very important, by the 20th century the breed's distinctive markings and color were written into the standard, becoming an essential feature. Terrier only in name, the Boston Terrier has lost most of its ruthless desire for mayhem, preferring the company of humans, although some males will still challenge other dogs if they feel their territory is being invaded.
