Bulldog,  also known as the British Bulldog or English Bulldog, is a medium-sized dog breed. It is a muscular, hefty dog with a wrinkled face and a distinctive pushed-in nose. The Kennel Club (UK), the American Kennel Club (US), and the United Kennel Club (US) oversee breeding records. According to the American Kennel Club (AKC), a Bulldog's disposition should be 'equable and kind, resolute, and courageous (not vicious or aggressive), and demeanor should be pacifist and dignified. These attributes should be countenanced by the expression and behavior'. Wide stance Breeders have worked to reduce/remove aggression from these dogs. The dog that grabbed the bull by the nose and pinned it to the ground would be the victor. It was common for a bull to maim or kill several dogs at such an event, either by goring, tossing, or trampling.
