Often confused with Pit Bulls, American Staffordshire Terriers are equally strong and muscular. Despite their friendly demeanor with humans, they are often restricted due to their fighting history.
They require firm training, constant socialization, and an experienced handler, making them a challenge for first-time owners. In parts of Australia and Europe, owning an American Staffordshire Terrier is either completely banned or requires a special license.
Why They’re Banned: Strength, fighting history, and potential aggression. Where They’re Banned: Australia, parts of Europe, and some U.S. states.
