AKC standard for English Bulldogs
Coat - The coat should be straight, short, flat, close, of fine texture, smooth and glossy. (No fringe, feather or curl.) Skin - The skin should be soft and loose, especially at the head, neck and shoulders. Wrinkles and Dewlap - The head and face should be covered with heavy wrinkles, and at the throat, from jaw to chest, there should be two loose pendulous folds, forming the dewlap.
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.
1 GENERAL APPEARANCE
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.
Shoulders - The shoulders should be muscular, very heavy, widespread and slanting outward, giving stability and great power. Forelegs - The forelegs should be short, very stout, straight and muscular, set wide apart, with well developed calves, presenting a bowed outline, but the bones of the legs should not be curved or bandy, nor the feet brought too close together. Elbows - The elbows should be low and stand well out and loose from the body. Feet - The feet should be moderate in size, compact and firmly set. Toes compact, well split up, with high knuckles and very short stubby nails. The front feet may be straight or slightly out-turned.

It should be well let down between the shoulders and forelegs, giving the dog a broad, low, short-legged appearance. Chest - The chest should be very broad, deep and full. Underline - The body should be well ribbed up behind with the belly tucked up and not rotund. Back and Loin - The back should be short and strong, very broad at the shoulders and comparatively narrow at the loins.
