bull terrier was once known as a fierce gladiator. A Bull Terrier might have a preventive effect, and it will certainly defend its owner in a truly critical situation. Bull terriers are known to be courageous, scrappy, fun-loving, active, clownish and fearless. They become very attached to their owners. The Bull Terrier thrives on a firm, consistent leadership and affection. This breed can be a pet if very thoroughly socialized and trained. If they do not get enough physical and mental exercise they may be too energetic for small children. Children should be taught how to display leadership towards the dog. Meek owners will find them to become very protective, willful, possessive and/or jealous. Bull Terriers may try to join into family roughhousing or quarrel. Bull Terriers generally must be given a lot of structure.[2] Unaltered males may not get along with other male dogs
