The American Staffordshire Terrier, or “AmStaff,” is a breed that commands respect. With his broad head, powerful jaws, and muscular body, he looks like a tank. But inside that tough exterior beats a heart of gold. The AmStaff is one of the most people-oriented breeds in existence. He is famously affectionate, eager to please, and deeply devoted to his family.

Historically, the breed has a complex past, often confused with the American Pit Bull Terrier. While they share common ancestors, the AmStaff has been bred separately for decades, specifically for conformation show and a stable, reliable temperament. Today, he excels not just as a show dog, but as a therapy dog, search-and-rescue worker, and beloved family pet.

History and Origin: From Fighters to Friends

The AmStaff’s history is intertwined with the bloody sport of dog fighting. In 19th-century England, Bulldogs were crossed with Terriers to create dogs with the strength of the Bulldog and the gameness of the Terrier. These dogs, known as “Bull and Terriers,” were brought to America by immigrants.

In the US, these dogs were used as all-around farm dogs. They caught wild hogs, guarded the homestead, and were companions to the children. American breeders wanted a larger, heavier dog than the English version. In 1936, the AKC accepted the breed under the name Staffordshire Terrier. In 1972, the name was changed to American Staffordshire Terrier to distinguish it from the smaller Staffordshire Bull Terrier of England.

Despite their fighting past, the breed was always noted for its loyalty to humans. In fact, the most decorated dog of World War I was Sergeant Stubby, a Bull Terrier mix who looks very much like an AmStaff. He warned soldiers of gas attacks and even captured a German spy, earning him a promotion to Sergeant.

Temperament and Personality: The People Pleaser

The AmStaff is defined by his love for people.

The Lover

He is affectionate to the point of being sticky. He wants to be in your lap, on your bed, and generally as close to you as physically possible. He is excellent with children, earning him the nickname “Nanny Dog” in some circles (though no dog should be left unsupervised with kids).

The Worker

He is intelligent and eager to please. He thrives on having a job. Whether it’s obedience, agility, or weight pulling, he wants to work for you.

The Dog Aggression

While he loves people, he can be aggressive toward other dogs. This is a trait from his fighting ancestors. Early and extensive socialization is crucial. Many AmStaffs do best as the only pet in the home.

Training and Exercise Needs

Exercise

The AmStaff is an athlete.

• Daily: A vigorous walk, jog, or game of fetch is mandatory. A flirt pole is an excellent tool for burning energy.
• Sports: They excel in weight pulling, dock diving, and obedience.
• Mental Stimulation: A bored AmStaff is a destructive AmStaff. Puzzle toys and training sessions are essential.

Training

He is smart but strong-willed.

• Leadership: You must be a confident, consistent leader. He will test you.
• Positive Reinforcement: He responds best to praise and treats. Harsh methods can lead to stubbornness or fear.
• Leash Manners: Because of his strength, he must be taught not to pull on the leash early.

Health and Lifespan

AmStaffs are generally healthy, living 12 to 16 years.

• Hip Dysplasia: Common in muscular breeds.
• Skin Allergies: Atopy (environmental allergies) can cause itching and skin infections.
• Heart Disease: Subaortic Stenosis (SAS) is a concern.
• Cerebellar Ataxia: A neurological condition affecting balance. Responsible breeders test for this (NCL-A).
• Thyroid Issues: Hypothyroidism can occur.

Grooming and Care

The AmStaff is low-maintenance.

• Brushing: Weekly brushing with a stiff bristle brush keeps the coat shiny.
• Bathing: Only when dirty.
• Nails: Keep them short.
• Teeth: Regular brushing is important.

Nutrition

AmStaffs have hearty appetites.

• Quality: High-quality protein helps maintain muscle mass.
• Weight: Watch their weight carefully. Obesity puts strain on their joints.
