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 from the AKC standard. They should be either black, brindle or seal with white markings. Boston Terriers 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 Terrier is around 11 to 13 years, though some can live up to around 18 years. They have a short nose, which can often cause breathing problems later in life, which is what leads to a low life expectancy.
The American Kennel Club ranked the Boston Terrier as the 21st most popular breed in 2019.
