The Boston terrier breed originated around 1875, when Robert C. Hooper of Boston purchased from Edward Burnett a dog named Judge (known later as Hooper's Judge), which was of a bull and terrier type lineage. Hooper's Judge is directly related to the original bull and terrier breeds of the 19th and early 20th centuries. The American Kennel Club cites Hooper's Judge as the ancestor of all true modern Boston Terriers.Judge weighed about 32 pounds (15 kg). Judge was bred to Burnett's Gyp (or Kate). Gyp was a white bulldog-type female, owned by Mr. Edward Burnett, of Southboro, MA. She weighed about 20 pounds, was stocky and strong and had the typical blocky head now shown in Bostons. From this foundation of the breed, subsequent breeders refined the breed into what we know of it today. Bred down in size from fighting dogs of the bull and terrier types, the Boston Terrier originally weighed up to 44 pounds (20 kg) (Old Boston Bulldogs).
