Here’s the uncomfortable headline you’ll see every few years: the English Bulldog is headed for extinction. It makes for a dramatic story, and there’s real science underneath it. But framing it as extinction gets the problem backward. The Bulldog isn’t vanishing for lack of interest, the breed is one of the most popular on earth. It’s being crushed by the very look we made popular. The threat isn’t that Bulldogs will disappear. It’s that the standard we keep breeding toward has painted the breed into a genetic corner it can’t easily back out of.
A widely cited genetic study found that the English Bulldog no longer carries enough diversity in its gene pool to breed its way out of trouble. In plain terms: the population is so inbred that you can’t simply select healthier purebred Bulldogs and cross them to fix the crippling airway and skeletal problems, because the healthy genes to draw on have largely been bred out. Understanding how a dog got into that corner is the key to seeing the only real way out.
How a bull-baiting dog became a companion
The Bulldog’s story starts somewhere grim. In the early 1800s, Bulldogs were bred for bull-baiting, a brutal blood sport. When Parliament outlawed baiting in 1835 (an early animal-cruelty law championed by the RSPCA), the working Bulldog was suddenly a dog without a job, the kind of breed that historically just faded away, the way the old Wolfhound did once wolves were gone from Britain.
What saved the Bulldog was Victorian sentimentality. Starting around 1840, dog fanciers began reinventing former working breeds as show dogs and companions, softening their temperament and reshaping their bodies. The American Kennel Club recognized the breed in 1886, and from the 1890s on, breeders selected from a shrinking set of genes to exaggerate the features people found charming: the flat, baby-like face, the low squat build, the corkscrew tail. Every time a “cute” trait was locked in, other genetic variation, including genes that quietly protect health, was lost from the pool for good.
The look is the illness
Over the last few decades, the market pushed those exaggerations even further, because buyers kept rewarding the most extreme version of the face and body. The result is a dog whose signature appearance and signature health problems are the same thing.
The English Bulldog ranks second among all breeds for congenital-disease deaths in puppies. The flat, brachycephalic skull that gives the breed its face also gives it a compressed airway, and upper-respiratory disease is a leading cause of death in the breed. On top of that sit chondrodysplasia (a skeletal disorder driving hip and elbow dysplasia) and a long list of problems with the skin, teeth, heart, eyes, and immune system. These aren’t unlucky individual dogs. They’re the predictable output of a standard that treats a struggling airway and a deformed skeleton as the goal.
“When the thing that makes a breed recognizable is also the thing sending it to my exam room, that’s not bad luck, that’s a design problem,” says Dr. Priya Nair. “The kindest thing we can do for the Bulldog is loosen the standard enough to let a healthy dog exist inside it.”
The way out is deliberate, not sentimental
If the healthy genes are largely gone from the purebred population, the only durable fix is to bring diversity back in from outside, through careful outcrossing with related breeds to rebuild a functional genome. Some breeders are already doing versions of this, working toward a more moderate, “old-fashioned” Bulldog with a longer muzzle, a less extreme build, and a body that can breathe, walk, and cool itself without a fight. The trade-off is honest: a healthier Bulldog will look a little less extreme than the show-ring ideal. Whether enough enthusiasts will accept that trade is the real question hanging over the breed.
If you love this breed, the most powerful lever is your wallet and your standards as a buyer. Reward breeders who prioritize open airways, moderate faces, health testing, and genetic diversity over the flattest face and the most wrinkles. Demand shapes supply, and right now demand is still asking for the version of the dog that suffers most.
What’s new since this was written
Two developments have sharpened the picture considerably. In 2022, a court in Norway effectively banned the breeding of English Bulldogs (and Cavalier King Charles Spaniels), ruling that breeding dogs toward these extreme, unhealthy conformations violates the country’s Animal Welfare Act. It was one of the first times a national legal system said, in effect, that the standard itself was the welfare problem.
That same period brought a large VetCompass study from the UK’s Royal Veterinary College, comparing English Bulldogs against all other dogs across real veterinary records. The numbers are stark: English Bulldogs were found to be over 38 times more likely to develop skin-fold dermatitis, nearly 27 times more likely to have cherry eye, and around 20 times more likely to suffer the airway obstruction (brachycephalic obstructive airway syndrome) that defines the breed’s breathing struggles. The researchers were blunt about the stakes, warning that without a shift toward more moderate features, the breed could face bans elsewhere too. The science and the law are now saying the same thing: moderate the Bulldog, or lose the freedom to breed it at all.
