Originated around 1870 in Boston from a bull-and-terrier dog named Hooper's Judge, bred to a bulldog-type female named Gyp.

The Mastiff & Bull family. Heavy-boned guardians and the bull breeds descended from them. Powerful but often gentle at home, they need early training and socialization.

Friendly, bright and amusing.

Voice

Usually quiet; barks when there's a reason.

With kids

A family favorite that thrives around children.

Other dogs

Generally sociable with other dogs.

Home

A natural apartment dog.

Exercise. Moderate: daily walks and active play, such as a game of fetch. Puppies do better with several short sessions than one long walk, and older dogs need gentler outings.

Training. Eager and responsive. Picks up basic manners quickly and enjoys learning tricks.

Short, smooth coat: a weekly once-over with a rubber curry mitt or bristle brush and an occasional bath. Light shedding.

For every dog: trim nails when you can hear them click on the floor, brush teeth daily if you can (a few times a week still helps), and clean ears about once a month, drying them well after baths and swims.

Daily calories

About 400–690 kcal for a healthy adult

Dry food

Roughly 1–1.75 cups a day at ~400 kcal per cup

Puppies eat four small meals a day at 6 to 12 weeks, drop to three somewhere between 3 and 6 months, and move to two meals a day from about 6 months.

Keep treats, including training treats and table scraps, under 10% of daily calories.

Calories use the resting-energy formula from the Merck Veterinary Manual (70 × body weight in kg^0.75) times a maintenance factor of 1.4 to 1.8, so very active or working dogs may need more. Cups assume about 400 kcal per cup; check your food's label. Treat any feeding chart as a starting point and adjust to body condition.

Typical lifespan is 11–13 years. Conditions reported in the breed:

Ask breeders for health-test results from the parents (hips, eyes, and DNA tests where relevant), and schedule yearly vet checkups.
