They were bred to excel in blood sports and expect to fight one another or with bear or bulls in 18th and 19th century.

Some experts suggest that Amstaff were the mix of White English Terrier and Black-and-Tan Terrier. The well-bred Amstaff of today is more soft and gentle than his pit-fighting ancestors. The American Kennel Club officially registered Amstaff as terrier group in 1975.
