Breed Info

In 1936, Amstaffs were accepted for registration in the American Kennel Club (AKC) Stud Book as Staffordshire Terriers, belonging to the terrier and molosser groups. The name of the breed was revised January 1, 1972 to American Staffordshire Terrier; breeders in the United States had developed a variety which was heavier in weight than the Staffordshire Bull Terrier of England. The name change was to distinguish them as separate breeds.

Images of the breed were used to represent the US during the 1900s as a depiction of strength and dignity.


Children friendly

Responsible breeders have focused on creating a dog with a sound, reliable temperament around humans. The average AmStaff is playful, gentle and tolerant. Most well-socialized AmStaffs are good with children, but as with any dog, AmStaffs and children should always be supervised when together.

People Oriented

The AmStaff is a people-oriented dog that thrives when he is made part of the family and given a job to do. Friendly and loyal to his family, they will protect them from any threat. Early socialization and growing up with other animals can reduce the AmStaff's tendencies to not get along well with other pets.

Coat & Grooming

The short, smooth coat of the American Staffordshire Terrier can come in a variety of colors, including blue, fawn, white, black, and red. They can include a mix of colours or a mix of white and brindle. Overall, American Staffordshire Terriers' grooming needs are fairly low. They shed twice yearly.

Agile Athletes

Every inch the athlete, this breed has remarkable strength. Despite its brawn, it is quick and nimble. This breed needs a vigorous daily workout, along with some mind games, in order to be at its best. A trainer who can meet the physical demands of the American Staffordshire Terrier and keep them busy and under control will have a devoted, affectionate, and obedient companion for life.

This is a smart, gentle, loving dog who wants and needs to spend lots of time with his people. A fun-loving freethinker, the Amstaff takes well to training when it’s done in a positive manner with lots of food, games, rewards and praise. In fact, although they have a reputation as being guard dogs, they are likely to greet strangers with lots of licks and affection. It is mostly their muscular build, broad head and strong jaws that intimidates intruders and keeps them away. That said, many AmStaff Terrier owners claim that dogs of this breed are great judges of character and know people’s intent, and they can make excellent watchdogs for that reason.

American Staffordshire Terriers should be given a diet formulated for a mid-to-large size dog with moderate energy levels. You should consult your veterinarian or professional nutritionist for advice on what to feed your American Staffordshire Terrier and what size portions they require. Their needs will change with age, so be sure to make adjustments from puppyhood to adulthood and old age as recommended.
