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.[2] Color and markings are important when distinguishing this breed to the AKC standard. They should be either black, brindle or seal with white markings.[3][4] Bostons are small and compact with a short tail and erect ears.The AKC says they are highly intelligent and very easily trained.[5] 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.
