The United Kennel Club states that
This breed has indomitable courage, high intelligence and tenacity. Coupled with its affection for its friends, and children in particular, its quietness and trustworthy stability make it an all-purpose dog. However, the organization cautions that their standards are only intended for those already familiar with the breed.
The Staffordshire bull terrier is not a breed of dog recommended for first time owners or owners that cannot provide the dog with their undivided attention. Staffies are known for their loyalty to their family if trained well, but they can still cause harm to other animals or people due to their slightly erratic temperament.
