This term is often used to encompass several breeds, including the American Pit Bull Terrier, American Staffordshire Terrier, and Staffordshire Bull Terrier.
Tosa Inus, also known as Japanese Mastiffs, were originally bred for dog fighting in Japan. Their imposing size and fighting background have raised concerns about their potential for aggression, leading to their ban in the UK.
Japanese Tosas are large, muscular dogs bred for dog fighting in Japan. Known for their strength and territorial nature, they are banned in the UK under the Dangerous Dogs Act. Owning or breeding a Japanese Tosa is a criminal offense.
The Dogo Argentino is a large, powerful breed originally bred for hunting big game, including wild boar and pumas. Their hunting instincts and strong prey drive are considered concerning, leading to their prohibition in the UK.
Fila Brasileiros, also known as Brazilian Mastiffs, are known for their loyalty and protective instincts. However, their tendency to be territorial and aggressive toward strangers led to their inclusion in the banned breeds list.
Czechoslovakian Wolfdogs are a hybrid breed created by crossing German Shepherds with Carpathian wolves. They possess a wild appearance and, due to their wolf heritage, can exhibit unpredictable behavior, which has resulted in their prohibition in the UK.
Similar to the Czechoslovakian Wolfdog, Saarloos Wolfdogs are hybrids, with European wolves in their lineage. These dogs have an independent streak and require experienced handlers. Concerns over their behavior and potential danger to the public have led to their ban.
Though American Bulldogs are not banned outright, they fall under the "Type 1" category of banned Pit Bull Terrier types if they exhibit specific physical characteristics.
