Many of the jurisdictions that restrict pit bulls apply their restriction to the modern American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier, and any other dog that has the substantial physical characteristics and appearance of those breeds. Such jurisdictions include the Canadian province of Ontario, and the U.S. cities of Miami and Denver. However, a few jurisdictions, such as Singapore, also classify the modern American Bulldog as a "pit bull-type dog". In the United Kingdom, a pit bull is an American Pit Bull Terrier.
