Responsible breeders have focused on creating a dog with a sound, reliable temperament around humans. That breeding history is why many AmStaffs (as their friends call them) have incredibly trustworthy temperaments with their families. 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. Interaction with other animals, especially other dogs, should be closely monitored.
The AmStaff wasn't meant to be a hop-to-it obedience whiz, and he isn't. If you try to force him, he will always win. If you try to make it a game, he will always play, and you will both win. Despite its tough dog persona the AmStaff is a breed that loves to love.
