The American Staffordshire Terrier, often referred to as the Amstaff, is a medium to large sized dog breed that originated in the United States.
Males usually measure between 45 and 48 centimeters in height at the withers, while females measure between 43 and 46 centimeters.
Males weigh on average between 25 and 35 kilograms, while females weigh between 20 and 30 kilograms.
Their coat is short, smooth, and shiny, and can be solid or variegated with shades of black, blue, red, fawn, and white. They have a broad, square head with strong, powerful jaws. Their ears are triangular and erect, and their eyes are round and dark. Their tail is often docked and carried high.
Amstaffs are muscular, athletic and resilient dogs. They are intelligent, loyal and affectionate towards their family, but can be suspicious of strangers. Although they have a reputation as aggressive dogs, it is important to note that their behavior is largely dependent on their socialization and training. Well-behaved and socialized Amstaffs can be loyal, lovable, and kind companions.
Amstaffs need regular exercise and mental stimulation to stay healthy and happy. They also need regular grooming to keep their coat in good condition. Amstaffs are considered a working dog breed, and can be successfully trained in sports such as obedience, agility, and defense.
