The French Bulldog is a small companion breed that the FCI describes as powerful for its size, short, stocky and smooth-coated, with a snub nose, erect ears and a naturally short tail.[1]
The breed standard
The FCI standard sets a height at the withers of 27–35 cm for males and 24–32 cm for females, and a weight of 9–14 kg for males and 8–13 kg for females. The coat is smooth, close and glossy, without undercoat, in fawn or brindle with or without white spotting. Black, black and tan, and all dilutions of black are disqualifying colours.[1] The nose is snubbed, but the standard requires that the slope of the nostrils and the upturned nose allow normal nasal breathing. Completely closed nostrils and respiratory distress are disqualifying faults.[1] The temperament is described as sociable, lively, playful and possessive.[1] In a study of UK veterinary records, adult French Bulldogs averaged 12.7 kg.[2]
Name and origin
The FCI says the dog is probably descended, like all mastiffs, from molossers of Epirus and the Roman Empire, and is a relative of the British Bulldog. It states that the breed as known today is the product of crossings by enthusiasts in the working-class quarters of Paris in the 1880s, whose owners were market porters, butchers and coachmen before it won over high society and the artistic world. The first breed club was founded in Paris in 1880, the first registration dates from 1885, and the French Kennel Club recognised the breed in 1898.[1] The Royal Kennel Club and a UK veterinary study both trace part of the ancestry to the Toy Bulldog of Great Britain in the 1850s; the Kennel Club recognised the breed in 1906.[3][2]
Health and lifespan
In a life-table study of UK veterinary records, life expectancy at birth was 4.53 years, the shortest of 18 breeds, while the age at which remaining life expectancy fell to 1.5 years was 10–11.[4] The breed is very recent in the UK, with a young population of fast-growing numbers, so these figures are not a typical lifespan. The median age of the French Bulldogs in a 2013 UK study was only 1.3 years.[2]
In that study, 72.4% of dogs had at least one recorded disorder. The commonest were ear infection (14.0%), diarrhoea (7.5%), conjunctivitis (3.2%), overlong nails (3.1%) and skin-fold dermatitis (3.0%). The authors suggest breathing problems were probably under-recorded.[2] The Royal Kennel Club notes that dogs with a very flat face and short muzzle have a higher risk of certain health issues.[3]
Popularity
The American Kennel Club recognised the French Bulldog in 1898.[5] It ranked 1st on the AKC’s list of most popular breeds in 2025.[6] In UK veterinary records, the French Bulldog’s share of newly born dogs rose from 0.02% in 2003 to 1.46% in 2013.[2]
