At a glance
The Bull Terrier is the 'white cavalier' — a robust, big-boned terrier with a long, egg-shaped head, erect ears and small triangular eyes glistening with good humour, created in 19th-century England from Bulldog and the now-extinct White English Terrier and refined into a gentleman's companion. Bull Terriers are playful, charming and mischievous — the ultimate 'personality breed', a clown with a jaunty stride that thrives on affection and is, the CKC says, a friend to mankind — but they are also independent free-thinkers with a higher commitment to fun and games than to a work ethic, and the AKC scores them 1/5 with other dogs. The AKC's four keys to their happiness are early socialisation, firm but loving training, ample exercise and lots of time with their adored humans.

Health
This page is general information compiled from published sources. It is not veterinary, legal or purchase advice. Dogs vary within a breed — talk to a vet or a reputable breeder about the dog in front of you.
Health notes are not veterinary advice. Conditions listed are those reported for the breed, not a diagnosis of any dog. Always consult a veterinarian.
Heart conditions
Certain heart conditions are reported in the breed; breeders may have breeding stock examined by a veterinary cardiologist. Ask your vet about heart checks at routine visits.
Patellar luxation
Patellar luxation (slipping kneecaps) is commonly reported in small breeds; breeders screen for it. Ask your vet if your dog skips or holds up a hind leg.
Congenital deafness
Congenital deafness is reported in the breed; puppies can be BAER hearing-tested. Ask your breeder about hearing tests.
Kidney disease
Kidney conditions are reported in the breed. Ask your vet about routine blood and urine checks.
Behaviour
The ultimate 'personality breed'
The AKC calls the Bull Terrier the ultimate 'personality breed' — with early socialisation with dogs and people, firm but loving training, ample exercise and lots of quality time with its adored humans there is no more loyal, lovable and entertaining companion — but reminds owners it has the Bulldog's tenacity and courage in a terrier package: an independent free-thinker with a higher commitment to fun and games than to a work ethic, that will do anything if it is fun and otherwise asks 'why bother?', so make training fun with food or toys; its trait chart scores other dogs 1/5. The CKC calls it a friend to mankind with a clownish personality and jaunty demeanour that thrives on affection and suits almost any size of home, but says owners must commit to shaping a dog that can be stubborn and likes to do things its own way.
Busy until two, easygoing after
The AKC says Bull Terriers benefit from daily, moderate exercise with good mental and physical stimulation — long walks with the family — and that their great strength and agility suit obedience, tracking, agility and coursing ability tests, as well as flyball, weight pull, carting, detection, search-and-rescue and therapy work. The CKC says the mature Bull Terrier is relatively easygoing at home while young dogs up to two are substantially more active and busier, and that the recipe for success is socialisation, family time and plenty of exercise; the Royal Kennel Club suggests up to 1 hour a day.
Energy and exercise
Energy level is rated 4/5 (high) on the AKC breed-trait chart. The Royal Kennel Club puts its exercise need at "up to 1 hour per day".
Training and barking
AKC trait chart: trainability 3/5, barking level 3/5. Individual dogs vary; early socialisation and reward-based training are recommended for every breed.

What owners say
Owner advice is quoted from public community posts and reflects those owners' opinions, not PocketPaw's position. It is unverified and not a substitute for professional advice. Each item links to where it was said.
“The parent club's health statement, which also forms part of its Code of Ethics, says both stud dogs and bitches should be health-tested before breeding and annually where required — at minimum a physical examination, a parasite check and four specific screenings: the heart, by auscultation before and after exercise and ideally an echocardiogram by a specialist; the kidneys, by an annual urine protein-creatinine ratio that should be below 0.5; hearing, with a BAER test on every puppy before it leaves for its new home and bilateral hearing in all breeding animals; and the patellas, which should be free of luxation. It adds that it is not always possible to prevent inherited disease and that a breeder's obligation is to make every effort and share health information openly.”
