Stocky and square with large bat ears, the French bulldog is the smallest of the bulldog breeds. While the American Kennel Club has no official height range for the French bulldog, most average 10 to 12 inches at the shoulders. The AKC restricts show dogs to 28 pounds or less. The AKC standard for all bulldogs mandate the circumference of the skull be at least the same as the dog's height at the shoulders.
