What it's like

In temperament the French Bulldog is affectionate, playful and alert, closely attached to its people and inclined to follow them from room to room. It tends to bark less than many small breeds but makes an attentive watchdog, and it can be stubborn when training does not interest it.

Living with one

Heat is a real risk for a Frenchie, so on hot days keep its exercise to the cool of the morning or evening. Bred for company, it needs a modest amount of exercise compared with other breeds. The short coat sheds through the year and needs only a weekly brush.

Size and growth

A French Bulldog is a small dog, heavier than a Pug and lighter than a Cocker Spaniel. Males end up a little heavier than females. It is one of the heaviest small breeds.

It is compact, muscular and heavy-boned for its size, with a broad square head, a short flat muzzle, a wrinkled face and large upright bat ears that are the breed's trademark. The tail is short, either straight or screwed. The smooth, fine coat comes in colours including brindle, fawn, cream and pied, often with a dark mask.

Puppy growth

By about 5 months, a male French Bulldog puppy is already as heavy as a grown Cavalier King Charles Spaniel. They grow fastest between 3 and 4 months old.

Health and lifespan

Vets record these more often in Frenchies than in crossbreeds or other dogs. Breathing obstruction from a short muzzle (life-limiting), narrowed nostrils, skin fold inflammation and ear discharge are far more likely. Difficult birth (serious) is much more likely. These are figures for the breed as a whole, not a prediction for your dog.

Flat face and breathing

The French Bulldog is one of the flat-faced breeds. In UK vet records, flat-faced dogs were more likely to have breathing and airway problems than dogs with a medium-length muzzle, and lived shorter lives on average. Noisy breathing at rest is worth raising with a vet.

Lifespan

In UK vet records, the typical French Bulldog lived to about 10 years, shorter than the typical small breed. Flat-faced breeds as a group live shorter lives than breeds with a longer muzzle.

Where it comes from

The French Bulldog was made by crosses in working-class 1880s Paris, where it belonged to "market porters, butchers and coachmen" before high society and artists adopted it. Its American club traces those small bulldogs back to Nottingham lace-makers who took them to northern France. When an English judge at the 1897 Westminster show rewarded only rose ears, American fanciers wrote a standard allowing the bat ear alone4,14.

The French Bulldog moved quickly from the Paris streets into fashionable homes across Europe and North America around the turn of the twentieth century, valued as a small, sturdy town dog. In Britain, some bulldog breeders resisted it at first, seeing it as an undersized version of their own breed, but the Kennel Club recognised it as a separate breed early in the twentieth century. One French Bulldog, Gamin de Pycombe, was among the dogs lost with the Titanic. The breed was developed as a companion, and that has remained its role.

Breed standard

The French Bulldog is judged against standard no. 101, in group 9, Companion and Toy Dogs4.

Questions people ask

General guidance for dogs rather than a measured French Bulldog figure: most females have a first season somewhere between six and fifteen months, and cycles then settle to roughly every 180 days. Smaller breeds tend to start earlier and larger ones later, so a small breed is most likely at the early end.
