The Boston Terrier is one of the few breeds of dog that America can claim as its own. Around 1870, Robert C. Hooper of Boston purchased Hooper's Judge, a cross between an English Bulldog and an English White Terrier. Hooper's Judge was bred with a smaller female, and that litter bred with French bulldogs, providing the beginnings of the Boston Terrier, America's first non-hunting dog. Though originally bred for dog fighting, Boston Terriers are no longer used for that purpose and the aggressive traits have been bred out of the breed.

Also know as the Boston Bull, Boston Terriers are compact, muscular dogs with short, wide muzzles, dark, large round eyes, short tails and pointy erect ears. Their short coats come in black and white or brown and white and are easy to groom. Some breeders have tried selling all white Boston Terriers as rare. However, an all white coloring generally indicates a genetic weakness, making them more prone to health problems. Though Boston Terriers do shed, it is not excessive and with regular brushing, the shedding is easy to manage. Baths are only given when necessary.

With the proper care, Boston Terriers can live 15 years or longer, but usually average about 13 years. Boston Terriers will grow to an average of 15 to 17 inches in height and 10 to 25 pounds in weight. Their smaller size makes them suitable for all types of living environments including apartments. Boston Terriers do need regular sessions of walking and playtime, and do not require large amounts of space for their exercise. They are sociable and friendly dogs that are described as intelligent and energetic. Boston Terriers make good family pets and companions and are generally good around children and other pets. They make fair watchdogs; some Boston Terriers will bark only when necessary and others will never bark.

Boston Terriers are prone to breathing problems, due to their short snouts. Some of them will snore when sleeping, which can be a sign of a more serious medical condition, but it can be corrected with surgery. Exercise caution when out in excessive heat and humidity with a Boston Terrier, as they are more prone to heat exhaustion due to their short snouts. Boston Terriers are more likely to experience problems with heart and skin tumors and are more likely to suffer eye injuries due to their prominent eyes.
