The English Bulldog, listed by the AKC simply as the Bulldog, descends from the Old English Bulldog, a dog used for bull-baiting until England outlawed the sport in 1835. Afterward it was remade into a companion that kept the massive head, loose wrinkled skin, undershot jaw and low, wide body, but gained a much gentler nature. Adults usually weigh 40 to 55 pounds and wear a short, smooth coat.
Most Bulldogs are calm and good-humored, happiest with short walks and long naps. The flat face is what matters most here: breathing trouble and poor heat tolerance make indoor air conditioning a must where summer days regularly pass 90°F. Skin folds need regular cleaning, and a lean weight protects the joints. Bulldogs vary, so each dog's own personality and health say more than the breed's tough reputation.
