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.
