Temperament
Bull Terriers are known as friendly, outgoing dogs and for even having a clownish attitude about them. Their physical strength is matched by their intelligence, and both their body and mind need to be kept active. They can be fun and playful. As a breed they are generally placid and will not normally make the first move.
Bull Terriers as Pets
Bull Terriers are very affectionate dogs that love human company, and are particularly good with children. However, they are usually not considered ideal for a first-time dog owner. They have a high pain threshold, which reduces the risk of injury from a defensive bite. Younger dogs may regard children as playmates, and because of their strength can cause inadvertent injury.
They are protective of children in their charge. Because of their fondness of people, Bull Terriers do not make the best guard dogs, but they will defend their "pack" if needed.
