The '''Bulldog''' is a British [[dog breed|breed]] of dog of [[mastiff]] type. It may also be known as the '''English Bulldog''' or '''British Bulldog'''. It is a medium-sized, muscular dog of around {{convert|40|-|55|lb|kg|0|abbr=on}}. They have large heads with thick folds of skin around the face and shoulders and a relatively flat face with a protruding lower jaw. The breed has significant health issues as a consequence of breeding for its distinctive appearance, including [[Brachycephalic airway obstructive syndrome|brachycephaly]], [[Hip dysplasia (canine)|hip dysplasia]], heat sensitivity, and skin infections. Due to concerns about their quality of life, breeding Bulldogs is illegal in [[Norway]] and the [[Netherlands]].
'''Bulldog''' is the name for a breed of [[dog]] commonly referred to as the '''English Bulldog'''. Other Bulldog breeds include the [[American Bulldog]], [[Old English Bulldog]] (now extinct), [[Olde English Bulldogge]], and the [[French Bulldog]]. The Bulldog is a muscular, heavy dog with a wrinkled face and a distinctive pushed-in nose.<ref name="Get to Know the Bulldog">[http://www.akc.org/sitesearch/index.cfm?q=bulldog "Get to Know the Bulldog"], 'The American Kennel Club', Retrieved 29 May 2014</ref> The [[American Kennel Club]] (AKC), [[The Kennel Club]] (UK), and the [[United Kennel Club]] (UKC) oversee breeding standards. Bulldogs are the 5th most popular purebreed in the United States in 2013 according to the American Kennel Club.<ref>[http://www.akc.org/reg/dogreg_stats.cfm American Kennel Club 2013 Dog Registration Statistics Historical Comparisons & Notable Trends], ''The American Kennel Club'', Retrieved 29 May 2014</ref>

The modern Bulldog was bred as a [[companion dog]] from the [[Old English Bulldog]], a now-extinct breed used for [[bull-baiting]], when the sport was outlawed in England under the Cruelty to Animals Act. 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, modern Bulldogs are generally friendly, amiable dogs. Bulldogs are now commonly kept as pets; in 2013, the Bulldog was the 12th most frequently registered breed worldwide.{{r|skk}}

Bulldogs are one of the few breeds whose tail is naturally short and either straight or screwed and thus is not cut or [[Docking (dog)|docked]] as with some other breeds. A straight tail is a more desirable tail according the breed standard set forth by the BCA if it is facing downward, not upwards.

The term "Bulldog" was first mentioned in literature around 1500, the oldest spelling of the word being Bondogge and Bolddogge. The first reference to the word with the modern spelling 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".<ref>{{cite book|author=Jesse, George R. |title=Researches into the history of the British Dog, from ancient laws, charters, and historical records: With original anecdotes, and illustrations of the nature and attributes of the dog, from the poets and prose writers of ancient, mediaeval, and modern times.

A 2004 UK survey found the leading cause of death of Bulldogs to be cardiac-related (20%), cancer (18%), and old age (9%).<ref name="kcsurvey">{{cite journal | last=Adams | first=V.

The designation "bull" was applied because of the dog's use in the sport of [[bull baiting]]. This entailed the setting of dogs (after placing wagers on each dog) onto a tethered bull. 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. 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. Bull-baiting, along with bear-baiting, reached the peak of its popularity in England in the early 1800s until they were both made illegal by the [[Cruelty to Animals Act 1835]]. This amended the existing legislation to protect animals from mistreatment and included (as "cattle") bulls, dogs, bears, and sheep, so that bull and bear-baiting as well as [[cockfighting]] became prohibited. Therefore, the Old English Bulldog had outlived its usefulness in England as a sporting animal and its active or "working" days were numbered. However, emigrants did have a use for such dogs in the New World. In mid-17th century New York, Bulldogs were used as a part of a citywide roundup effort led by Governor [[Richard Nicolls]]. Because cornering and leading wild bulls was dangerous, Bulldogs were trained to seize a bull by its nose long enough for a rope to be secured around its neck.<ref>Ellis, Edward Robb (2005).

===Brachycephaly===
Despite slow maturation so that growing up is rarely achieved by two and a half years, bulldogs' lives are relatively short. At five to six years of age they are starting to show signs of aging.

===Other conditions===
In time, the original old English Bulldog was crossed with the [[pug]]. The outcome was a shorter, wider dog with a [[Cephalic index#Brachycephalic animals|brachycephalic]] skull. Though today's Bulldog looks tough, he cannot perform the job he was originally created for as he cannot withstand the rigors of running and being thrown by a bull, and also cannot grip with such a short muzzle.

The oldest single breed specialty club is The Bulldog Club (England), which was formed in 1878. Members of this club met frequently at the Blue Post pub on [[Oxford Street]] in [[London]]. There they wrote the first standard of perfection for the breed. In 1894 the two top Bulldogs, King Orry and Dockleaf, competed in a contest to see which dog could walk 20 miles. King Orry was reminiscent of the original Bulldogs, lighter boned and very athletic. Dockleaf was smaller and heavier set, more like modern Bulldogs. King Orry was declared the winner that year, finishing the 20-mile walk while Dockleaf collapsed.<ref>The sun., 11 September 1894, [http://chroniclingamerica.loc.gov/lccn/sn83030272/1894-09-11/ed-1/seq-4/;words=orry+Dock+Orry+Leaf Page 4, Image 4]</ref> The Bulldog was officially recognized by the American Kennel Club in 1886.<ref name="Get to Know the Bulldog"/>

A British study found [[demodicosis]] to be more prevalent in the Bulldog than other breeds. The overall prevalence was 1.5% in the breed compared to the 0.17% rate for all dogs.

Some individuals of this breed are prone to interdigital cysts—cysts that form between the toes. These cause the dog some discomfort, but are treatable either by vet or an experienced owner. They may also suffer from respiratory problems. Other problems can include [[cherry eye]], a protrusion of the inner eyelid (which can be corrected by a veterinarian), [[Allergy|allergies]], and [[hip]] issues in older Bulldogs.

The folds, or "rope," on a Bulldog's face should be cleaned daily to avoid infections caused by moisture accumulation. Some Bulldogs' naturally curling tails can be so tight to the body as to require regular cleaning and ointment.


=== Controversies and legal status ===
Like all dogs, Bulldogs require daily [[exercise]]. If not properly exercised it is possible for a Bulldog to become overweight, which could lead to heart and lung problems, as well as stress on the joints.<ref>Denizet-Lewis, Benoit (22 November 2011) [http://www.nytimes.com/2011/11/27/magazine/can-the-bulldog-be-saved.html Can the Bulldog be Saved?] ''[[The New York Times]]''.</ref>

[[File:English Bulldog about to sleep.jpg|thumb|left|English Bulldog about to sleep]]
Bulldogs have very small nasal cavities and thus have great difficulty keeping their bodies cool. Bulldogs are very sensitive to heat. Extra caution should be practiced in warmer climates and during summer months. Bulldogs must be given plenty of shade and water, and must be kept out of standing heat.<ref name="Get to Know the Bulldog"/> Air conditioning and good ventilation are required to keep them healthy and safe. Bulldogs actually do most of their sweating through the pads on their feet and accordingly enjoy cool floors. Like all [[brachycephalic]], or "short faced," breeds, Bulldogs can easily become overheated and even die from [[hyperthermia]].<ref name="Get to Know the Bulldog"/> (see [[Brachycephalic syndrome]]) They can be big snorters and heavy breathers, and they tend to be loud snorers. Bulldog owners can keep these issues under control by staying aware and protecting their Bulldog(s) from these unsafe conditions. In 2014 the Dutch Kennel Club implemented some breeding rules to improve the health of the Bulldog. Among these is a fitness test where the dog has to walk 1&nbsp;km (0.62 miles) in 12 minutes.

The designation "bull" was applied because of the dog's use in the sport of [[bull-baiting]]. This entailed the setting of dogs (after placing wagers on each dog) onto a tethered bull. 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 over them.<ref>{{Cite web |title=Bulldog origin |url=https://www.nebkc.com/bulldog-origin-1 |access-date=2024-02-20 |website=NEBKC |language=en}}</ref> 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.<ref>{{Cite web |title=Bulldog origin |url=https://www.nebkc.com/bulldog-origin-1 |access-date=2024-02-20 |website=NEBKC |language=en}}</ref> Bull-baiting was made illegal in England by the [[Cruelty to Animals Act 1835]].<ref>{{cite book |last1=Curnutt |first1=Jordan |url=https://books.google.com/books?id=p2p0MptGeBkC |title=Animals and the Law: A Sourcebook |date=2001 |publisher=ABC-CLIO |isbn=978-1-57607-147-2 |page=284 |access-date=13 September 2020 |archive-url=https://web.archive.org/web/20230121213803/https://books.google.com/books?id=p2p0MptGeBkC |archive-date=21 January 2023 |url-status=live}}</ref> Therefore, the [[Old English Bulldog]] had outlived its usefulness in England as a sporting animal and its "working" days were numbered. However, emigrants did have a use for such dogs in the New World. In mid-17th century New York, Bulldogs were used as a part of a citywide roundup effort led by Governor [[Richard Nicolls]]. Because cornering and leading wild bulls was dangerous, Bulldogs were trained to seize a bull by its nose long enough for a rope to be secured around its neck.<ref>Ellis, Edward Robb (2005).

Bulldog
Other namesEnglish Bulldog,
British Bulldog
OriginEngland[1]
NotesNational animal of United Kingdom
Dog (domestic dog)

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 medium-sized, muscular dog of around 40–55 lb (18–25 kg). They have large heads with thick folds of skin around the face and shoulders and a relatively flat face with a protruding lower jaw. The breed has significant health issues as a consequence of breeding for its distinctive appearance, including brachycephaly, hip dysplasia, heat sensitivity, and skin infections. Due to concerns about their quality of life, breeding Bulldogs is illegal in Norway and the Netherlands.

The modern Bulldog was bred as a companion dog from the Old English Bulldog, a now-extinct breed used for bull-baiting, when the sport was outlawed in England under the Cruelty to Animals Act. 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, modern Bulldogs are generally friendly, amiable dogs. Bulldogs are now commonly kept as pets; in 2013, the Bulldog was the 12th most frequently registered breed worldwide.[2]

Description

[edit]

Appearance

[edit]

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.[3] They have short tails that can either hang down straight or be tucked in a coiled "corkscrew" into a tail pocket.

In the United Kingdom, the breed standards are 55 lb (25 kg) for a male and 50 lb (23 kg) for a female.[4] In the United States, the standard calls for a smaller dog — a typical mature male weighs 50 lb (23 kg), while mature females weigh about 40 lb (18 kg).[5]

Temperament

[edit]

According to the American Kennel Club (AKC), a Bulldog's disposition should be "equable and kind, resolute, and courageous (not vicious or aggressive), and demeanour should be pacifist and dignified. These attributes should be countenanced by the expression and behaviour".[6]

Bulldogs are known for getting along well with children, other dogs, and other pets.[7][8]

Health

[edit]

Lifespan

[edit]

A 2022 study in the UK of veterinary data found a life expectancy of 7.39 years, the second lowest of all breeds in the study.[9] A 2024 UK study found a life expectancy of 9.8 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds.[10]

A 2004 UK survey found the leading cause of death of Bulldogs to be cardiac-related (20%), cancer (18%), and old age (9%).[11]

Brachycephaly

[edit]

Evolution of brachycephalia in Bulldogs. Left to right, the skulls are from approximately the 1910s, 1960s, and 1980s.

The shortened snout and pushed in face of the Bulldog is known as brachycephaly.[12][13] Brachycephaly results in deformation of the upper airway tract and leads to obstruction of breathing.[14] Effects of brachycephaly are stridor, stertorous breathing, emesis, skin fold dermatitis, brachycephalic airway obstructive syndrome, exophthalmos, pharyngeal gag reflex, cyanosis, and laryngeal collapse.[15][16][17][18][19][20][21] Other issues arising from brachycephaly are risk of complications whilst under anaesthesia,[22] and hyperthermia — with the latter caused due to an inability to effectively reduce body temperature via panting.[23] Many airlines ban the breed from flying in the cargo hold due to a high rate of deaths from air pressure interacting poorly with their breathing problems.[24]

Other conditions

[edit]

Statistics from the Orthopedic Foundation for Animals indicate that of the 467 Bulldogs tested between 1979 and 2009 (30 years), 73.9% were affected by hip dysplasia, the highest amongst all breeds.[25] Similarly, the breed has the worst score in the British Veterinary Association/Kennel Club Hip Dysplasia scoring scheme, although only 22 Bulldogs were tested in the scheme.[26]

A study in England found the Bulldog to have a nearly three times greater risk of patellar luxation, with 2.9% of all Bulldogs having the condition.[27]

In a 1963 UK study, 17% of Bulldogs surveyed had skin fold dermatitis.[28] The breed is also predisposed to atopic dermatitis.[29]

A study by the Royal Veterinary College found that Bulldogs are a much less healthy breed than average, with over twice the odds of being diagnosed with at least one of the common dog disorders investigated in the study.[30]

Over 80% of Bulldog litters are delivered by Caesarean section because their characteristically large heads can become lodged in the mother's birth canal and to avoid potential breathing problems for the mother during labour.[31][32]

A British study found demodicosis to be more prevalent in the Bulldog than other breeds. The overall prevalence was 1.5% in the breed compared to the 0.17% rate for all dogs. For dogs aged under 2 years, the prevalence was 3.6% compared to 0.48%.[33]

The Bulldog is one of the two most commonly affected breeds for hiatal hernia.[34]

[edit]

In January 2009, after the BBC documentary Pedigree Dogs Exposed, The Kennel Club introduced revised breed standards for the British Bulldog, along with 209 other breeds, to address health concerns. Opposed by the British Bulldog Breed Council, it was speculated by the press that the changes would lead to a smaller head, fewer skin folds, a longer muzzle, and a taller thinner posture, to combat problems with respiration and breeding due to head size and width of shoulders.[35] In 2019 the Dutch Kennel Club implemented some breeding rules to improve the health of the Bulldog. Among these is a fitness test where the dog has to walk 1 km (0.62 miles) in 12 minutes. Its temperature and heart rate have to recover after 15 minutes.[36]

In 2014, the Dutch government forbade the breeding of dogs with a snout shorter than a third of the skull, including Bulldogs, a law that it began enforcing in 2019.[37] In 2022, the Oslo District Court made a ruling that banned the breeding of Bulldogs in Norway due to their propensity for developing health problems. In its verdict the court judged that no dog of this breed could be considered healthy, therefore using them for breeding would be a violation of Norway's Animal Welfare Act.[38][39]

History

[edit]
Painting of a Bulldog from 1790 by English artist Philip Reinagle.

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".[40] In 1666, English scientist Christopher Merret applied: "Canis pugnax, a Butchers Bull or Bear Dog", as an entry in his Pinax Rerum Naturalium Britannicarum.[41]

The designation "bull" was applied because of the dog's use in the sport of bull-baiting. This entailed the setting of dogs (after placing wagers on each dog) onto a tethered bull. 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 over them.[42] 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.[43] Bull-baiting was made illegal in England by the Cruelty to Animals Act 1835.[44] Therefore, the Old English Bulldog had outlived its usefulness in England as a sporting animal and its "working" days were numbered. However, emigrants did have a use for such dogs in the New World. In mid-17th century New York, Bulldogs were used as a part of a citywide roundup effort led by Governor Richard Nicolls. Because cornering and leading wild bulls was dangerous, Bulldogs were trained to seize a bull by its nose long enough for a rope to be secured around its neck.[45]

Bulldogs as pets were continually promoted by dog dealer Bill George.[46]

In 1864, a group of Bulldog breeders under R. S. Rockstro founded the first Bulldog Club. Three years after its opening the Club ceased to exist, not having organized a single show. The main achievement of the Rockstro Bulldog Club was a detailed description of the Bulldog, known as the Philo-Kuan Standard. Samuel Wickens, treasurer of the club, published this description in 1865 under the pseudonym Philo-Kuan.[47][better source needed]

On 4 April 1873, The Kennel Club was founded, the first dog breeding club dealing with the registration of purebred dogs and dog breeds.[48][non-primary source needed] Bulldogs were included in the first volume of the Kennel Club Stud Book, which was presented at the Birmingham Show on 1 December 1874. The first English Bulldog entered into the register was a male dog named Adam, born in 1864.[citation needed]

Bulldog from 1915

In March 1875, the third Bulldog Club was founded, which still exists today.[49][50][better source needed] Members of this club met frequently at the Blue Post pub on Oxford Street in London. The founders of the club collected all available information about the breed and its best representatives and developed a new standard for the English Bulldog, which was published on 27 May 1875, the same year they held the first breed show. Since 1878, exhibitions of the club were held annually, except during the Second World War. On 17 May 1894, the Bulldog Club was granted the status of a corporation and since then has carried the official name "The Bulldog Club, Inc.". It is the oldest mono-breed dog kennel club in the world.[51][better source needed]

The Bulldog was officially recognised by the American Kennel Club in 1886.[3]

In 1894, the two top Bulldogs, King Orry and Dock Leaf, competed in a contest to see which dog could walk 20 miles (32 km). King Orry was reminiscent of the original Bulldogs, lighter-boned and very athletic. Dock Leaf was a smaller and heavier set, more like modern Bulldogs. King Orry was declared the winner that year, finishing the 20-mile (32 km) walk while Dock Leaf collapsed and expired.[52] Though today Bulldogs look tough, they cannot perform the job they were originally bred for, as they cannot withstand the rigours of running after and being thrown by a bull, and also cannot grip with such a short muzzle.[53]

Cultural significance

[edit]

Bulldogs are a national symbol of British culture

Bulldogs are often associated with determination, strength, and courage due to their historical occupation, though the modern-day dog is bred for appearance and friendliness and not suited for significant physical exertion. They are often used as mascots by universities, sports teams, and other organizations. Some of the better-known Bulldog mascots include Georgetown's Jack, Butler's Blue IV, Yale's Handsome Dan, the University of Georgia's Uga, Mississippi State's Bully, and the United States Marine Corps' Chesty.[54][55]

The Bulldog originated in England and has a longstanding association with British culture; the BBC wrote: "To many the Bulldog is a national icon, symbolising pluck and determination".[56] During the Second World War, the Prime Minister Winston Churchill was likened to a Bulldog for his defiance of Nazi Germany.[57]
