The perfect Bulldog must be of medium size and smooth coat, with heavy, thick-set, low-swung body, massive short-faced head, wide shoulders and sturdy limbs. The general appearance and attitude should suggest great stability, vigor and strength. The disposition should be equable and kind, resolute and courageous (not vicious or aggressive), and demeanor should be pacific and dignified. These attributes should be countenanced by the expression and behavior.
Size, Proportion, Symmetry
Size: The size for mature dogs is about 50 pounds; for mature bitches about 40 pounds.
Eyes and Eyelids: The eyes, seen from the front, should be situated low down in the skull, as far from the ears as possible, and their corners should be in a straight line at right angles with the stop. They should be quite in front of the head, as wide apart as possible, provided their outer corners are within the outline of the cheeks when viewed from the front. They should be quite round in form, of moderate size, neither sunken nor bulging, and in color should be very dark. The lids should cover the white of the eyeball, when the dog is looking directly forward, and the lid should show no "haw."
Neck, Topline, Body
Neck: The neck should be short, very thick, deep and strong and well arched at the back.
Shoulders: The shoulders should be muscular, very heavy, widespread and slanting outward, giving stability and great power.
Legs: The hind legs should be strong and muscular and longer than the forelegs, so as to elevate the loins above the shoulders. Hocks should be slightly bent and well let down, so as to give length and strength from the loins to hock. The lower leg should be short, straight and strong, with the stifles turned slightly outward and away from the body. The hocks are thereby made to approach each other, and the hind feet to turn outward.
Coat and Skin
Coat: The coat should be straight, short, flat, close, of fine texture, smooth and glossy. (No fringe, feather or curl.)
Color of Coat
The color of coat should be uniform, pure of its kind and brilliant. The various colors found in the breed are to be preferred in the following order: (1) red brindle, (2) all other brindles, (3) solid white, (4) solid red, fawn or fallow, (5) piebald, (6) inferior qualities of all the foregoing. Note: A perfect piebald is preferable to a muddy brindle or defective solid color. Solid black is very undesirable, but not so objectionable if occurring to a moderate degree in piebald patches. The brindles to be perfect should have a fine, even and equal distribution of the composite colors. In brindles and solid colors a small white patch on the chest is not considered detrimental. In piebalds the color patches should be well defined, of pure color and symmetrically distributed.
The style and carriage are peculiar, his gait being a loose-jointed, shuffling, sidewise motion, giving the characteristic "roll." The action must, however, be unrestrained, free and vigorous.
The disposition should be equable and kind, resolute and courageous (not vicious or aggressive), and demeanor should be pacific and dignified. These attributes should be countenanced by the expression and behavior.
