The French Bulldog also known as the Frenchie is a small dog. Frenchies were the result in the 1800s of a cross between bulldog ancestors imported from England and local ratters in Paris (France).
The origin of the modern French Bulldog breed descends directly from the dogs of the Molossians, an ancient Greek tribe. The dogs were spread throughout the ancient world by Phoenician traders. British Molossian dogs were developed into the Mastiff. A sub-family of the Mastiff were the Bullenbeisser, a type of dog used for bull-baiting.
Blood sports such as bull-baiting were outlawed in England in 1835, leaving these "Bulldogs" unemployed. However, they had been bred for non-sporting reasons since at least 1800, and so their use changed from a sporting breed to a companion breed. To reduce their size, some Bulldogs were crossed with terriers, while others were crossed with pugs. By 1850 the Toy Bulldog had become common in England, and appeared in conformation shows when they began around 1860. These dogs weighed around 16–25 pounds (7.3–11.3 kg), although classes were also available at dog shows for those that weighed under 12 pounds (5.4 kg).
At the same time, lace workers from Nottingham, displaced by the Industrial Revolution, began to settle in Normandy, France. They brought a variety of dogs with them, including miniature Bulldogs. The dogs became popular in France and a trade in imported small Bulldogs was created, with breeders in England sending over Bulldogs that they considered to be too small, or with faults such as ears that stood up. By 1860, there were few miniature Bulldogs left in England, such was their popularity in France and due to the exploits of specialist dog exporters.
The small Bulldog type gradually became thought of as a breed, and received a name, the Bouledogue Francais. This Francization of the English name is also a contraction of the words "boule" (ball) and "dogue" (mastiff or molosser). The dogs were highly fashionable and were sought after by society ladies and Parisian prostitutes alike, as well as creatives such as artists, writers, and fashion designers. However, records were not kept of the breed's development as it diverged further away from its original Bulldog roots. As it changed, terrier and Pug stock may have been brought in to develop traits such as the breed's long straight ears, and the roundness of their eyes.
The New Complete Dog Book: Official Breed Standards and All-New Profiles for 200 Breeds, 21st Edition, is an official publication of the American Kennel Club and sets forth the Official Breed Standard for all breeds recognized by the AKC, including the French Bulldog. The French Bulldog should have the appearance of an active, muscular dog, of heavy bone, smooth coat, compactly built, and of medium or small structure. The points should be well distributed and bear good relation one to the other, no feature being in such prominence from either excess or lack of quality that the animal appears deformed or poorly proportioned. In comparison to specimens of different gender, due allowance should be made in favor of the female dogs, which do not bear the characteristics of the breed to the same marked degree as do the male dogs.
Acceptable colors under the breed standard are the various shades of brindle, fawn, tan or white with brindle patches (known as "pied"). The most common colors are brindle, then fawn, with pieds being less common than the other colors. The breed clubs do not recognize any other colors or patterns. This is because some colors come linked with genetic health problems not usually found in the breed, most notably blue coloration, which is linked with a form of alopecia (hair loss or baldness), sometimes known as "Blue Dog Alopecia". Although this is heavily disputed by some organizations, there does appear to be an indication that the health, hair and/or skin conditions are caused by the color pigment (melanin) clumping in the hairshaft itself. Even dogs that are not blue can suffer from "blue dog alopecia" or canine follicular dysplasia. The American Kennel Club states that Frenchies can be brindle, fawn, white, and brindle and white. The skin should be soft and loose, especially at the head and shoulders, forming wrinkles. Coat moderately fine, brilliant, short and smooth.
The AKC French Bulldog Standard states: Acceptable colors - All brindle, fawn, white, brindle and white, and any color except those which constitute disqualification. Unacceptable colors include: black; black and fawn; black and white; cream and white; fawn and black; fawn brindle and white; and gray and white.
The head should be large and square. The top of the skull should be flat but slightly rounded. The stop should be well defined, causing a hollow or groove between the eyes. The muzzle should be broad, deep, and well laid back; the muscles of the cheeks well developed. The nose should be extremely short; nostrils broad with well defined line between them. The nose and flews should be black, except in the case of lighter-colored dogs, where a lighter color of nose is acceptable. The flews should be thick and broad, hanging over the lower jaw at the sides, meeting the underlip in front and covering the teeth, which should not be seen when the mouth is closed. The under-jaw should be deep, square, broad, undershot, and well turned up. Eyes should be wide apart, set low down in the skull, as far from the ears as possible, round in form, of moderate size, neither sunken nor bulging, and in color dark. No haw and no white of the eye showing when looking forward. Ears shall hereafter be known as the bat ear, broad at the base, elongated, with round top, set high in the head, but not too close together, and carried erect with the orifice to the front. The leather of the ear fine and soft.
The neck should be thick and well arched, with loose skin at throat. The forelegs should be short, stout, straight and muscular, set wide apart. The body should be short and well rounded. The back should be a roach back, with a slight fall close behind the shoulders. It should be strong and short, broad at the shoulders and narrowing at the loins. The chest, broad, deep and full, well ribbed with the belly tucked up.
The hind legs should be strong and muscular, longer than the forelegs, so as to elevate the loins above the shoulders. Hocks well let down. The feet should be moderate in size, compact and firmly set. Toes compact, well split up, with high knuckles and short stubby nails; hind feet slightly longer than forefeet. The tail should be either straight or screwed (but not curly), short, hung V low, thick root and fine tip; carried low in repose. Other than bat ears; black and white, black and tan, liver, mouse or solid black (black means without any trace of brindle) ; eyes of different color; nose other than black except in the case of the lighter-colored dogs, where a lighter color of nose is acceptable; hare lip; any mutilation.
The French Bulldog, like many other companion dog breeds, requires close contact with humans. As a result, they should not be left alone for more than a few hours because these dogs suffer from separation anxiety if they are alone for too long. This is especially important when French Bulldogs are young, but this issue remains a concern into adulthood. Being alone for too long can cause a French Bulldog to behave in a destructive manner, which can include chewing on household items or furniture or even going to the bathroom in the house.
They have fairly minimal exercise needs, but do require at least daily short walks. The French Bulldog is sometimes called "Frog dog" or a "Clown dog". Frog dog is in reference to the unique way they sit with hind legs spread out. Clown dog is because they are known to be fun loving vivacious "clowns of the dog world". Their calm nature makes them an excellent choice for apartment dwellers, as does their sensible attitude towards barking.
Their bulk and their compromised breathing system makes it impossible for them to regulate their temperature efficiently. The French bulldog has only a single short coat. What this all means for the dog is that it becomes cold very easily. Also, they will very likely need to have some extra covering inside during the winter if you live in a particularly cold area. These dogs need warm clothing when out in cold weather. Precautions must be taken when exercising during hot or humid weather, as they are prone to heat stroke. It is also recommended that French Bulldogs who live indoors have access to air conditioning to regulate their temperature, provided the air conditioning is not set too low.
French Bulldogs make excellent companions. The French Bulldog rarely barks, and if he does it is to draw attention, to point out that he needs something (like attention). This breed is patient and affectionate with its owners, especially with children, who are especially protected by the females. French Bulldogs can easily live with other breeds when the proper introductions are done.
They are ranked 58th in Stanley Coren's The Intelligence of Dogs. There are certain exceptions to this average level of canine intelligence; a French Bulldog named Princess Jacqueline which died in 1934 was claimed to understand 20 words, reacting correctly.
A UK breed survey report on 71 dog deaths put the average lifespan of French Bulldogs at 8 to 10 years, while the UK breed club suggests an average of 12 to 14 years. The AKC lists that the French Bulldog breed has a lifespan of 11 to 13 years.
As a result of the compacted airway and the bulk of the French bulldog, they have an inability to effectively regulate their body temperature. While a regular canine may suffer to some degree from the heat, to a Frenchie it may be lethal. It is imperative that they be protected from temperature extremes at all times, and that they always have access to fresh water and shade. As they are a brachycephalic breed (see Brachycephalic syndrome), French Bulldogs are banned by several commercial airlines due to the numbers that have died while in the air. This is because dogs with snub noses find it difficult to breathe when they are hot and stressed out. The cargo space in an aircraft can rise as high as 30 °C (86 °F) when waiting on the runway.
Patellar luxation is the dislocation (slipping) of the patella (kneecap). In dogs, the patella is a small bone that shields the front of the stifle joint in its hind legs. This bone is held in place by ligaments. As the knee joint is moved, the patella slides in a groove in the femur. The kneecap may dislocate toward the inside (medial) or outside (lateral) of the leg. This condition may be the result of injury or congenital deformities (present at birth). Patellar luxation can affect either or both legs. Testing is available to predict the presence of patellar luxation in a dog.
Birth and reproduction
French bulldogs frequently require artificial insemination, and caesarean section to give birth, with over 80% of litters delivered this way. As well, many French bulldog stud dogs are incapable of naturally breeding. This is because French Bulldogs have very slim hips, making the male unable to mount the female to reproduce naturally. Typically, breeders must undertake artificial insemination of female dogs. Female French bulldogs can also suffer from erratic or 'silent' heats, which may be a side effect of thyroid disease or impaired thyroid function.
Back and spine
French bulldogs can also suffer from an assortment of back, disk and spinal diseases and disorders, most of which are probably related to the fact that they were selectively chosen from the dwarf examples of the bulldog breed. This condition is also referred to as chondrodysplasia. French bulldogs are prone to having congenital hemivertebrae (also called "butterfly vertebrae"), which will show on an x-ray. More advanced technologies such as myelograms, CT scans, or MRIs are used to detect spinal cord compression. Some breeders feel that only dogs that have been x-rayed and checked for spinal anomalies should be bred.
In October 2010, the UK French Bulldog Health Scheme was launched. The scheme consists of three levels, the basic vet check corresponding to the Bronze level, this covers all the Kennel Club Breed Watch points of concern for the breed. The next level, Silver, requires a DNA test for hereditary cataracts, a simple cardiology test, and patella grading. The Gold level requires a hip score and a spine evaluation. The European and UK French Bulldog fanciers and Kennel Clubs are ahead of the Americans and the AKC in moving away from the screw, cork-screw or 'tight' tail (which is an inbreed spinal defect), and returning to the short drop tail which the breed originally had. The UK breed standard now reads: "Tail Undocked, short, set low, thick at root, tapering quickly towards tip, preferably straight and long enough to cover anus. Never curling over back nor carried gaily."
