All members of the Chicago Bulldog Club must adhere to a Code of Ethics that includes breeding to the breed standard as outlined below.
COAT AND SKIN
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.
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 color of coat should be uniform, pure of its kind and brilliant.
Colors are red, white, fawn, fallow, or any combination of the foregoing.
Patterns and markings may include brindle, piebald, ticking, black masks, black tipping, and a minimal amount of black in piebalds.
All other colors or markings are a disqualification. The merle pattern is a disqualification.
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.
Blue or green eye(s) or parti-colored eye(s).
Brown or liver colored nose.
Colors or markings not defined in the standard.
