Vets are calling for urgent change to English bulldog breeding, as a new study suggests that the dog’s signature traits are causing the breed to be significantly less healthy than other breeds.
The biggest concern for O'Neil is that many of the health problems English bulldogs, which are also known as British bulldogs, suffer from “are directly linked to the extreme structure of their bodies that has been selectively bred for.”
English bulldogs have a shorter face with protruding lower jaw, heavier build, bowed legs, and the breed’s facial folds as a feature of appeal.
The shorter snouts predispose the dog to 24 times greater risk of jaw overbite and greater risks of breathing problems that can lead to heart and gastrointestinal problems. All of these problems contribute to the breed’s ill health and short lifespans.
Historically, English bulldogs were muscular and athletic dogs bred to attack bulls for sport. After this activity was banned in 1835, the aggressiveness of the breed was gradually bred out and the breed became show dogs instead.
Since 1873, the Kennel Club, an organization for show dogs, wrote new “breed standards” to describe the idealized and preferred appearance of the breed, with more exaggerated features than its canine ancestors.
In particular it had a shorter face with a protruding lower jaw, heavier build, and bowed forelegs, all of which reduced its capability for exercise, gave the dogs a calmer temperament, and a greater predisposition to various health defects including difficult birth.
Compared to other dog breeds, English bulldogs have double the risk of developing at least one disorder and typically have a shorter lifespan than other breeds.
In the study, the authors compared all available dogs under primary veterinary care at clinics in the United Kingdom under the VetCompass Programme in 2016.
The authors found that though most of the English bulldogs were younger, they were also heavier than other dogs, with more English bulldogs having at least one disorder than any other dogs.
English bulldogs had a median age of 2.65 years, while the average age of other breeds was 4.42 years, and only 10 percent of the English bulldogs were over 8 years old as compared to 25 percent of the other breeds.
However, though it is widely known that bulldogs often have poor health due to selectively breeding for their feature characteristics, the authors were concerned to find the breed still boasts wide popularity.
“Given the continued popularity of the breed, the body-shape of the typical pet English Bulldogs should be redefined towards more moderate physical characteristics,” O’Neill said.
“Doing so will not only improve the dogs’ health, but could also enable the UK to avoid following other countries in banning the English Bulldog on welfare grounds.”
