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. Boston is a gentle breed that typically has a strong, happy-go-lucky, and friendly personality with a merry sense of humour. Bostons are generally eager to please their owner and can be easily trained. They can be very protective of their owners, which may result in aggressive and territorial behavior toward other pets and strangers. In modern days, aside from being an excellent companion, the Boston Terrier also excels in all sorts of canine sports. The breed is increasingly popular in dog agility competitions, obedience training, rally obedience, tracking, dock diving, flyball, weight-pulling, barn hunting and lure coursing. Being such a versatile breed and with their outgoing personality and eagerness to meet new acquaintances, the Boston Terrier is a popular therapy dog.
