You are likely thinking of the French Bulldog, which is a smaller breed related to the English Bulldog.
French Bulldogs typically weigh between 16-28 pounds and stand 11-14 inches tall at the shoulder. They are known for their compact size and muscular build.
It's important to note that there are no "miniature" versions of any breed officially recognized by major kennel clubs. The term "miniature" is often used informally to describe smaller dogs within a breed, but it is not a standard or recognized classification.
