The GCR breed standard of a/an French Bulldog are as follows.
Sturdy, compact , solid, small dog with good bone, short, smooth coat. No point exaggerated, balance essential. Dogs showing respiratory distress highly undesirable.
Head square in appearance and in proportion to dog's size. Skull nearly flat between ears, domed forehead. The skin covering the skull and forehead should be supple enough to allow fine wrinkling when the dog is alert. Well defined muzzle, broad, deep and set back, muscles of cheeks well developed. Stop well defined. Lower jaw deep, square, broad, slightly undershot and turned up. Nose black and wide, relatively short, with open nostrils and line between well defined. Lips black, thick, meeting each other in centre, completely hiding teeth. Upper lip covers lower on each side with plenty of cushion, never so exaggerated as to hang too much below level of lower jaw. Slightly undershot. Teeth sound and regular, but not visible when the mouth is closed. Tongue must not protrude. 'Bat ears', of medium size, wide at base, rounded at top; set high, carried upright and parallel, a sufficient width of skull preventing them being too close together; skin soft and fine, orifice as seen from the front, showing entirely. The opening to the ear canal should be wide and open.
Neck should be powerful, well arched and thick, of moderate length. Forequarters should be set wide apart, straight boned, strong, muscular and short. Cobby, muscular and well rounded with deep wide brisket and ribs well sprung. Strong, gently roached back. Good 'cut up'. The body while broader at the shoulders should narrow slightly beyond the ribs to give definition to the relatively short, thick, strong, muscular loin. Hindquarters should be strong, muscular and relatively longer than forelegs with moderate angulation. Absolute soundness essential. Hocks well let down. Feet are small, compact and placed in continuation of line of leg, with absolutely sound pasterns. Hind feet rather longer than the fore-feet. Toes compact; well knuckled; nails short, thick and preferably black.
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.
Texture fine, smooth, lustrous, short and close.
Free and flowing. Soundness of movement of the utmost importance.
Full of courage, yet with clown-like qualities. Bat ears and short tail characteristic features of the breed.
