In 2013, the American Kennel Club (AKC) ranked the French Bulldog as the 11th most popular breed in the United States, enjoying a sharp rise in popularity from 54th place a decade before, in 2003. Eyes that are AKC Standard approved for French Bulldogs are dark and almost to the point of being black. Blue eyed French bulldogs are not AKC approved. The most common colors are brindle, then fawn, with pieds being less common than the other colors. The breed clubs do not recognize any other colors or patterns. This is because some colors come linked with genetic health problems not usually found in the breed.
