Bull Terrier

Also called English Bull Terrier, Bully

A muscular comedian with an egg-shaped head, loyal to its people and stubborn about almost everything else.

The Bull Terrier packs a powerful, compact body and one of the most playful personalities in the terrier world. It was created in nineteenth-century England and now lives mainly as a devoted, often ridiculous family companion. It needs company, structure and an owner who can laugh at its strong opinions.

Life with a Bull Terrier

Few breeds are as instantly recognizable, and few are as misunderstood. The Bull Terrier grew out of crosses between old bulldogs and terriers in early nineteenth-century England, dogs used in the blood sports of that era. In the 1850s and 1860s a Birmingham dealer named James Hinks refined an elegant all-white version that became fashionable with gentlemen, and colored Bull Terriers were later reintroduced. Over the following century, breeders steadily softened the temperament for companionship.

Today's dog is best described as a clown with muscles. Bull Terriers are affectionate, physical and endlessly entertaining. Many perform a strange slow-motion walk under hanging plants, curtains or tablecloths, a quirk owners call trancing or ghost walking. Nobody fully understands why they do it, but it appears harmless and is one of the breed's oddest traits.

They generally love people, including visitors, which makes them poor guard dogs despite their appearance. What they cope with less well is being left alone for long hours, or sharing space with a dog that challenges them. Careful early socialization with other dogs helps, yet many adults are happiest as the only dog, or living with a calm companion of the opposite sex.

A Bull Terrier also has a physical presence that surprises people. At 20 to 30 kg (45 to 66 lb) of dense muscle on a relatively short frame, it can knock over a child or an unsteady adult in a joyful greeting, so manners matter as much as affection.

What stands out

Training

Bull Terriers learn fast but do not always see the point of doing what you asked. Short, playful sessions using food and toys work much better than repetition or confrontation. Owners who turn training into a game, for example using a brief tug session as the reward for a solid down, often get impressive results from a breed with a stubborn reputation.

Care guides for the Bull Terrier

FeedingExpect a food thief. Bull Terriers are keen eaters, and many learn to open bins, raid shopping bags and clear a low table in seconds, so lidded storage and a clear kitchen counter are part of daily life.Read more Puppy growthPuppies grow rapidly and reach adult height by around 12 months, but the breed can take 18 months to two years to develop its full chest and muscle. During that time they are strong, clumsy and completely unaware of their own power.Read more ExerciseAn hour or so of daily activity, split between walks and vigorous play, suits most adults. Tug games, flirt poles, sturdy balls and pushing a large herding ball around a field all appeal to this breed.Read more GroomingThis is one of the easier coats to keep. A weekly rub with a rubber curry mitt removes loose hair and spreads natural oils, and a bath every couple of months, or after a muddy walk, is usually enough.Read more HealthHealth concerns in the breed include deafness, particularly in white dogs, inherited kidney disease (hereditary nephritis), heart conditions such as mitral valve disease and aortic stenosis, luxating patellas, skin allergies and compulsive behavior such as tail chasing. Lethal acrodermatitis is a rare, severe inherited disorder that now has a DNA test.Read more

Things owners are often surprised by

1A Birmingham dog dealer named James Hinks shaped the elegant all-white Bull Terrier in the mid-1800s.
2The long, downfaced head has no stop between skull and muzzle, giving the famous egg shape.
3White Bull Terriers have a higher rate of congenital deafness, so BAER hearing tests are standard for litters.
4The breed standard sets no weight or height limits and asks instead for maximum substance for the dog's size.
5The Miniature Bull Terrier is now a separate breed, capped at about 35.5 cm (14 in) at the shoulder.

Bull Terrier questions

Why does my Bull Terrier walk in slow motion under plants?

This is called trancing or ghost walking, and it is surprisingly common in Bull Terriers. The dog creeps very slowly under something that brushes its back, such as a plant, curtain or tablecloth, and seems almost hypnotized. The cause is not well understood, but it appears harmless in most dogs. If it becomes frequent or hard to interrupt, mention it to your vet.

Are Bull Terriers good family dogs?

Many are affectionate, playful and loyal family dogs that adore their people. They suit families with older, sturdy children best, because their strength and exuberance can knock over small children. They need plenty of company, structure and activity. Families who are out all day or who want a quiet, low-energy dog usually find the breed a poor match.

Can Bull Terriers live with other dogs?

Some live happily with other dogs, particularly if raised together and paired with a dog of the opposite sex. Others become intolerant of dogs as they mature, especially dogs of the same sex. Careful socialization helps but cannot guarantee the result. If you already have a dog, choose an adult Bull Terrier with a known history with other dogs, or seek a breeder's guidance.

What is the difference between a Bull Terrier and a Pit Bull?

They share distant ancestry in bulldog and terrier crosses, but they are separate types. The Bull Terrier is a recognized breed with an egg-shaped, downfaced head, small triangular eyes and a standard that has been refined since the 1800s. Pit bull is a loose term covering several breeds and types, most with a broader, more defined skull. Temperament and legal status also differ by country.

Do Bull Terriers need a lot of attention?

Yes. This is a people-focused breed that tends to struggle when left alone for long hours, and boredom can lead to chewing, barking or compulsive habits. A Bull Terrier is happiest when someone is home for much of the day, or when it has company, regular walks and games. Puzzle feeders and chews help fill quieter periods.
