Overview
The Bulldog was created in medieval England for bull-baiting, and its ancestors were selected for huge jaws and a high pain threshold. When England banned blood sports in 1835 the breed lost its job and nearly died out, so admirers spent decades reworking it into a companion, refining its contours and breeding away the aggression. That reshaping came at a documented cost: a study of 2,662 English Bulldogs found 2.04 times the odds of being diagnosed with at least one disorder compared with other dogs, with raised odds for 24 of 43 specific disorders, and its authors called for immediate redefinition of the breed toward a moderate conformation. A separate survey of 102 breeding Bulldogs found one paternal haplotype in 93% of dogs. None of this makes the Bulldog a bad dog, and it is genuinely docile and fond of children, but it is a dog that will need active medical management.

History
The rescue effort produced the first written breed standard for any dog. In 1865 Samuel Wickens published a set of points for the Bulldog under the pen name Philo-Kuon, a template meant to steer the animal toward the parlor. A second group formed The Bulldog Club in March 1875, issued its own standard that May, held the first Bulldog-only show the same year, and incorporated in 1894, making it the oldest single-breed kennel club in the world. The last recorded bull baiting in England took place in 1837, so the men writing those standards were describing a dog whose job had been gone for a generation.

Fun Facts
ðķ Three Eyelids
Dogs have three eyelids. A third one called a nictitating membrane helps protect and moisten the eye. You can sometimes spot it when a dog is sleepy!
ðķ Unique Nose Prints
A dog's nose print is as unique as a human fingerprint. No two are alike! Some kennel clubs have started using nose prints for identification.
ðķ Dogs Dream Too
Dogs dream just like humans do. Their REM sleep looks remarkably similar to ours. You'll notice twitching paws and little whimpers as they relive their day.
ðķ Born Blind and Deaf
Puppies are born completely blind and deaf. They rely entirely on smell and touch for their first two weeks of life. Their eyes and ears open around 2 weeks old.
ðķ Mental Fatigue is Real
Regular mental stimulation is just as tiring for dogs as physical exercise. Puzzle feeders and training sessions work wonders for a calmer, happier pup.
ðķ A Nose Built Different
A dog's sense of smell is estimated to be 10,000 to 100,000 times more sensitive than a human's. Their wet nose actually helps by trapping scent chemicals so they can be analyzed more effectively.

Did You Know?
The Bulldog we know is a deliberate reconstruction. When Britain banned blood sports in 1835 the breed lost its job and nearly disappeared, and admirers spent the following decades reworking it into a companion, breeding away the aggression and reshaping the body. A survey of 102 breeding Bulldogs later found a single paternal haplotype in 93% of them, a measure of how narrow the pool doing that rebuilding was.
