American Staffordshire Terrier vs Staffordshire Bull Terrier

Two muscular terriers needing training and socialization; the American Staffordshire is larger and strong-willed, the Staffordshire Bull smaller.

Verdict

The American Staffordshire Terrier and the Staffordshire Bull Terrier are muscular, short-coated dogs with matching energy, trainability and grooming scores, and about an hour of daily exercise. Both are loyal and physical, both need consistent training and socialization, and both profiles flag local breed restrictions and the need to manage the dog around other animals.

The American Staffordshire is the larger at 40 to 70 pounds and is described as confident and strong-willed, so its profile suits capable owners who can manage a strong dog. The Staffordshire Bull is smaller at 24 to 38 pounds, people-oriented and affectionate, and is rated better for children and for first-time owners than its larger relative, though older children are recommended.

Choose the American Staffordshire Terrier if

  • You are an experienced owner who wants a larger, devoted dog
  • You are committed to training and socialization
  • You have a secure yard and can handle a strong dog
  • You will not leave it with free access to other pets

Choose the Staffordshire Bull Terrier if

  • Your household has older children and you want a people-focused dog
  • You prefer a smaller, lighter dog
  • You will manage dog-to-dog behavior with care
  • You have checked local rules and insurance
