Bull Terrier
Also known as: English Bull Terrier, Bully
An unmistakable egg-headed, muscular terrier - exuberant, comical, affectionate and famously playful, sometimes called the "clown" of dogdom. Bull Terriers are intensely people-loving, bonding closely with their family and bringing enormous personality and joyful energy to an engaged, active home.
Origin and purpose
The Bull Terrier was created in 19th-century England by crossing Bulldogs with terriers, initially for blood sports and then refined by James Hinks into a striking white companion ("the White Cavalier"). The distinctive egg-shaped head was developed later. Today it is purely a companion and show breed.
Temperament
Breed authorities describe the Bull Terrier as friendly, exuberant, courageous and devoted, with a famously playful and clownish character, generally sociable with people. It can be reactive toward other dogs and needs consistent, upbeat training. As always, behaviour reflects the individual dog and its upbringing far more than the breed label (Morrill et al., Science 2022).
Health and longevity
The breed carries several heritable conditions. Buy from breeders who BAER-test, renal-screen and cardiac-screen their dogs.
