The Bull Terrier is a gladiator with a sense of humor. With his unique egg-shaped head and muscular body, he is arguably the most recognizable dog breed in the world. Originally bred for fighting, he has been transformed over the last century into a loving, comical companion.

He is affectionately known as “the kid in a dog suit.” He is exuberant, mischievous, tireless, and possesses a zest for life that is infectious. He loves to play and will invent games to keep himself (and you) amused. He is not a dog for the faint of heart or the house-proud; he is a force of nature.

History and Origin: The White Cavalier

The Bull Terrier was developed in England in the mid-19th century. Dogmen crossed the Bulldog (for strength and tenacity) with the now-extinct White English Terrier (for agility and spirit) to create “Bull and Terriers.” These early dogs were fighters. Around 1860, a breeder named James Hinks set out to refine the breed. He wanted a cleaner, more elegant dog—a “gentleman’s companion” who was stylish but still tough enough to defend himself. He bred for an all-white coat and the distinctive head shape. His creation was dubbed the “White Cavalier.” The breed gained popularity not just in the pit, but in the show ring and on the streets. General George S. Patton famously owned a Bull Terrier named Willie, who followed him everywhere during WWII.

Physical Characteristics

The Bull Terrier is a muscular powerhouse. He is dense and solid, like a coiled spring.

  • Height: 21-22 inches (53-56 cm).
  • Weight: 50-70 pounds (22-32 kg). There is no weight limit, but the dog should look balanced.

Distinctive Features

  • Head: This is the breed’s signature. It is long, strong, and oval, shaped like an egg. It is flat on top and curves gently down to the nose (the “Roman finish”). There is no stop (indentation between the eyes).
  • Eyes: Small, triangular, and sunken. They are dark and glitter with a piercing “varminty” expression. It is the only breed with triangular eyes.
  • Ears: Small, thin, and close together. They stand stiffly erect.
  • Body: Big-boned, muscular, and symmetrical. The chest is broad.
  • Colors: Originally only white. Today, “Colored” Bull Terriers (brindle, black, red, fawn, or tricolor) are a separate variety but identical in type.

Temperament and Personality: The Class Clown

Life is a game to a Bull Terrier, and he makes up the rules as he goes along.

The Playmate

He loves people. He is incredibly affectionate and often thinks he is a lap dog. He loves to play rough and tumble games. He is generally good with children, but his high energy and muscle mass mean he can accidentally knock them over.

The Obstinate One

He is famously stubborn. If he doesn’t want to do something, he won’t. He is an independent thinker who needs a reason to obey.

The Trance

Some Bull Terriers exhibit a unique behavior called “trancing” or “ghost walking,” where they creep slowly under hanging objects (like tablecloths or plants) with a glazed look in their eyes. It is harmless and hilarious.

Training and Exercise Needs

Exercise: Burn the Energy

The Bull Terrier has high energy.

  • Daily: He needs vigorous exercise every day. A long walk is good, but free play in a yard is better. He loves to chase balls.
  • Destruction: A bored Bull Terrier is a wrecking ball. He will chew through drywall, furniture, and tires. Keep him busy.

Training: The Challenge

Training a Bull Terrier is an exercise in patience.

  • Fun: Training must be fun. If it becomes repetitive, he will shut down or wander off. Use toys and food.
  • Leadership: You must be the leader. He will test you constantly.
  • Socialization: Early and ongoing socialization is critical. He can be aggressive toward other male dogs if not properly socialized.

Health and Lifespan

Bull Terriers are generally healthy, living 12 to 13 years.

  • Deafness: White Bull Terriers are prone to congenital deafness in one or both ears. Responsible breeders BAER test puppies.
  • Kidney Disease: Hereditary Nephritis is a serious concern.
  • Heart Disease: Valve defects and murmurs.
  • Skin Issues: Allergies and rashes, especially in white dogs.
  • Spinning: A compulsive disorder (tail chasing) that can be hard to stop.

Grooming and Care

The Bull Terrier is a low-maintenance dog.

  • Brushing: A weekly brushing with a rubber mitt keeps the coat shiny.
  • Bathing: As needed.
  • Sunscreen: White dogs can get sunburned on their ears and nose.
