Bulldog

Breed overview
The Bulldog is a British breed of dog of mastiff type. It may also be known as the English Bulldog or British Bulldog. It is a stocky, muscular dog of medium size, with a large head, thick folds of skin around the face and shoulders and a relatively flat face with a protruding lower jaw. Selective breeding for appearance has led to the Bulldog's increased susceptibility to various health problems including brachycephaly, hip dysplasia and heat sensitivity. The dogs are illegal to breed in the Netherlands because of concerns about their quality of life. The modern Bulldog was bred as a companion dog from the Old English Bulldog, a now-extinct breed used for bull-baiting until the sport was outlawed under the Cruelty to Animals Act of 1835. The Bulldog Club (in England) was formed in 1878, and the Bulldog Club of America was formed in 1890. While often used as a symbol of ferocity and courage, the modern Bulldog is generally a friendly, amiable dog. It is commonly kept as a pet; in 2013 it was the twelfth-most-frequently registered breed worldwide.
Breed facts
- The first reference to the word "Bulldog" is dated 1631 or 1632 in a letter by a man named Preswick Eaton where he writes: "procuer mee two good Bulldogs, and let them be sent by ye first shipp".
- In 1666, English scientist Christopher Merret applied: "Canis pugnax, a Butchers Bull or Bear Dog", as an entry in his Pinax Rerum Naturalium Britannicarum.
- The designation "bull" was applied because of the dog's use in the sport of bull-baiting.
- The dog that grabbed the bull by the nose and pinned it to the ground would be the victor.
- Over the centuries, dogs used for bull-baiting developed the stocky bodies and massive heads and jaws that typify the breed, as well as a ferocious and savage temperament.
Size and appearance
Bulldogs have characteristically wide heads and shoulders along with a pronounced mandibular prognathism. There are generally thick folds of skin on the brow; round, black, wide-set eyes; a short muzzle with characteristic folds called a rope or nose roll above the nose; hanging skin under the neck; drooping lips and pointed teeth, and an underbite with an upturned jaw. The coat is short, flat, and sleek with colours of red, fawn, white, brindle, and piebald. Bulldogs have short tails that can either hang down straight or be tucked in a coiled "corkscrew" into a tail pocket. Dogs weigh approximately 25 kg, bitches about 23 kg. Standard weights in the United States are lower, approximately 50 lb for dogs and 40 lb for bitches.
