Date of Origin



The American Staffordshire Terrier and the Staffordshire Bull Terrier descended from the same lines. The fist dog originally sprang from mixing the old type of Bulldog with some old terrier types, probably the English Smooth Terrier. The result was aptly called the Bull and Terrier, later to be dubbed the Staffordshire Bull Terrier. They gained passage to America in the late 1800s, where they became known as the Pit Bull Terrier, American Bull Terrier, and even Yankee Terrier. Americans favored a slightly bigger dog than the English preferred, and with time the two strains diverged.

In 1936, the AKC recognized the breed as the Staffordshire Terrier (the name was changed in 1972 to American Staffordshire Terrier). The Am Staff evolved to have a sweet and trustworthy disposition around people. Unfortunately, these dogs have sometimes appealed to people seeking them for their strength rather than their loving abilities. Beginning in the 1980s, Am Staffs sometimes found themselves the target of breed-specific laws aimed at banning or controlling certain types of dogs. Despite this, the Am Staff is extremely popular among people wanting a people- and fun-loving dog.


Typically docile and playful with their family, American Staffordshire Terriers are also generally friendly toward strangers as long as their family is present. They are generally very good with children. They are a protective breed and should be introduced to new dogs carefully. They are stubborn, tenacious, and fearless. For all of their tough persona, the most important thing in life to this breed is their family’s fond attention.


Am Staffs need a daily outlet for their energy, preferably in the form of a long walk on leash or a vigorous game in the yard. Coat care is minimal.
