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 banned the sport in 1835. Since then it has been reshaped into a companion with a massive head, loose wrinkled skin, an undershot jaw and a low, wide body, usually 40 to 55 pounds. Many are calm, friendly and dignified, though each dog's personality differs.
The flat face brings real trade-offs. Breathing trouble, poor heat tolerance, skin-fold infections and joint problems are common, and vet bills can run high. Lifespans tend to be 7 to 10 years. Adopters do best with an air-conditioned home, careful weight control and a veterinarian who knows flat-faced breeds, which matters in a place with both icy winters and muggy summers.
