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.

Some other breed characteristics and standards follow in this section in the next paragraph.


The AKC Standard weight for a French Bulldog is maximum 28 pounds.
 The head of a French bulldog should be square shaped and large along with ears that symbolized bat ears.
French bulldogs are also known as a flat faced breed.
Eyes that are AKC Standard approved for French Bulldogs are dark and almost to the point of being black.
Blue eyed French bulldogs are not AKC approved.
 The coat of a French bulldog should short haired and fine and silky.
Acceptable colors under the breed standard are the various shades of brindle, fawn, cream or white with brindle patches (known as "pied").
The fawn colors can be any light through red.
 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.
These include 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, it has been suggested that the health, hair and skin conditions are caused by the color pigment (melanin) clumping in the hair shaft itself.
Even dogs that are not blue can develop "blue dog alopecia" or canine follicular dysplasia.
