According to the FCI standard, the American Staffordshire Terrier is keenly alive to everything nearby. In everyday life, that means a nose inspecting every new object and a body with great strength for its size. Guide both well and you gain a deeply people-oriented companion.

Origins
The standard gives the USA as the country of origin but contains no breed history. According to the FCI breed page, the American Staffordshire Terrier was definitively recognised in 1936; the current German version of the standard dates from 1998. Like the smaller Staffordshire Bull Terrier, it belongs to the bull-type terriers.
Temperament
The standard describes its courage as proverbial. In family life, this dog is often playful, cuddly and strongly attached to its people. Its strength and persistence call for calm, consistent training and thorough socialisation with other dogs from puppyhood.
Exercise and activities
One to two hours of exercise daily, plus tasks for mind and body: search games, trick training and tug games with clear rules. Practise loose-lead walking early, while the dog is still small.
Grooming
The short coat is easy to care for. Brush once a week, trim nails and check the skin for redness.
Health
Two inherited neurological diseases have been described in the American Staffordshire Terrier. Late-onset neuronal ceroid lipofuscinosis, which causes balance and movement problems, results from a breed-associated ARSG gene variant found worldwide and is inherited recessively (Abitbol et al. 2010). Juvenile-onset polyneuropathy has also been described, with laryngeal paralysis in 10 of 14 dogs (Vandenberghe et al. 2018). Ask whether the parents have been tested for the ARSG variant and request the results.
Who is an American Staffordshire Terrier right for?
Experienced dog owners with plenty of time for training and activities who can safely handle a strong, affectionate dog. Some German federal states impose requirements for American Staffordshire Terriers. Before buying, ask the state and your municipality which rules apply to you.
Who is it less suitable for?
First-time owners without support from training classes, households with little time and anyone reluctant to deal with requirements and authorities.
