The English Bulldog, listed by the AKC simply as the Bulldog, descends from the extinct Old English Bulldog, which was used in bull-baiting until England banned the sport in 1835. Since then it has been a companion: a medium, heavy-set dog of roughly 40 to 55 pounds with a massive head, loose wrinkled skin, an undershot jaw and a short, smooth coat.
Most Bulldogs are calm, kind and dignified, though some are stubborn and a few guard food or toys. Their flat faces bring real care needs: breathing trouble, heat sensitivity, skin-fold infections and joint problems are common, and lifespans run about 7 to 10 years. In Naperville, that means a home with air conditioning, careful weight control and a vet who knows flat-faced breeds.
