Prehistory and The Birth of American Staffordshire Terrier
Staffordshire’s roots start from 19th century England. Initially, bulldogs and terriers were crossbred to produce a dog that was both powerful and agile. Once these dogs reached America, the focus of breeding moved to the bulldog’s and terrier’s temperament and improved it into a distinctive line called Amstaff American Staffordshire.
The breed was recognized in 1936 by the AKC and called it Staffordshire Terrier. Later on, in 1972 the breed name was changed to American Staffordshire Terrier to differentiate it from the Staffordshire Bull Terrier.

Temperament: Do AmStaffs Display Aggression?
American Staffords come with a thick, muscular body, and yet, they remain extremely gentle and loyal to their families. Given their deep bonds, AmStaffs remain great companions as well since they are deeply reliant on human interaction.
Key Traits
- Guarding and Loyal: With natural protective instincts, these dogs are always guarding their territory.
- Social and Lively: Balanced AmStaffs will need daily stimulation in a variety of forms, especially through exercise.
- Adaptive and Quick to Learn: An AmStaff responds greatly to motivational forms of reinforcement.

Busted Myth: American Staffordshire Terriers are not aggressive by nature. Regardless of the reason, when they act ‘out of line’ it is the result of poor upbringing. Socially predisposed issues—they encounter without care and attention—are factors that lead to disturbances in behavior. Still, with care, these can be deeply loving companions.
Being true to their stereotypes, these dogs need love and boundaries in equal measure. An American Stafford is nothing short of a true loving family member when raised right.
