Bull Terrier

The Bull Terrier is a British terrier breed developed in the nineteenth century from bulldog and terrier ancestry, later refined into the smooth, muscular dog with the famous egg-shaped head and small triangular eyes. Standard Bull Terriers and Miniature Bull Terriers are separate sizes in many registries, but both share the same bold outline and short, close coat. Early dogs were associated with vermin work, sport, and the old fighting-dog world; modern lines are kept mainly as companions, show dogs, and performance dogs. Colors include white, brindle, red, fawn, black brindle, and tricolor.

Bull Terriers are physically strong and often comic, stubborn, and intensely social with their people. They benefit from training that is clear and upbeat, since drilling or rough handling tends to produce resistance rather than reliability. Many have high chase drive and some are selective with other dogs, so early social exposure and sensible introductions matter. The coat is easy, but health screening is important for deafness, heart disease, kidney disease, patellas, and skin allergies; Miniatures also warrant attention to primary lens luxation in some lines.
