Overview
The Bull Terrier is instantly recognizable by its egg-shaped head and small triangular eyes. Muscular and playful, it is a robust, comical breed that combines terrier tenacity with a deep affection for its people.
Fun-loving, energetic, and endearingly stubborn, the Bull Terrier thrives on attention and activity. It is devoted and gentle with family but strong and mischievous, needing training, exercise, and companionship to be at its best.
History
Developed in 19th-century England from bulldog and terrier crosses, the Bull Terrier was later refined for its distinctive head and became a fashionable companion. Its clownish personality has kept it a beloved, characterful breed.
