The French Bulldog - Bouledogue Français - is a small companion breed of dog. The name suggests that France is the country of origin, but, in fact, the Americans and British may have played a larger role in the breed's development. The dogs are commonly called the Frenchie and are nicknamed "clowns" and frog dogs. French bulldogs are active but not sporty. They are muscular dogs with a smooth coat, snub nose and solid bone structure. Their physical appearance is characterized by naturally occurring 'bat ears' that are wide at the base and rounded at the top. Their tails are naturally short, not cropped, and can be straight or screwed, but not curly.
