Dog breed · England
The Staffordshire Bull Terrier, also called the Staffy or Stafford, is a purebred dog of small to medium size in the terrier group that originated in the northern parts of Birmingham and in the Black Country of Staffordshire, for which it is named. They descended from 19th-century bull terriers that were developed by crossing bulldogs with various terriers to create a generic type of dog generally known as bull and terriers. Staffords share the same ancestry with the modern Bull Terrier, although the two breeds developed along independent lines, and do not resemble each other. Modern Staffords more closely resemble the old type of bull terrier and were first recognised as a purebred dog breed by The Kennel Club of Great Britain in 1935.
Within the broad sweep of dog history, the story behind the modern Stafford is rather brief and somewhat confusing because of the multiple aliases attached to these dogs in centuries past, such as the "Patched Fighting Terrier", "Staffordshire Pit-dog", "Brindle Bull" and "Bull-and-Terrier". Similar crosses also had aliases such as half-and-halves and half-breds. Blood sports such as bull-baiting and bear-baiting were outlawed with the passing of the Cruelty to Animals Act 1835 by Parliament, making it illegal to bait animals but promoting the matching of dogs against each other. Dog breeders migrated away from the heavier bulldogs, and introduced terrier blood into their crosses for gameness and agility. These bull and terrier crosses produce
Temperament: The Stafford has a reputation for pugnacity; when challenged by another dog it is known to not back away. They have a mixed reputation in the UK, with some people associating the breed with chavs.
The Kennel Club notes that the breed is “bold, fearless and totally reliable” and well suited to families, with the breed standard noting its particular affinity with children.
Appearance: The Stafford is short-haired, and of roughly equal length from the withers to the tail and from the withers to the ground. The coat is short, stiff and close. It may be white; black, blue, fawn or red, all with or without white; or any variety of brindle, with or without white. It has a broad head; the ears fold at the tip. It is muscular and well-boned, with strong shoulders, a wide chest and wide-set legs. It is agile and quite active. It is a terrier, and is so classified by the Kennel Club and the Fédération Cynologique Internationale. The dog usually stands 36–41 cm (14–16 in) at the withers. Dogs weigh about 13–[dose — ask your vet] (29–37 lb); bitches approximately [dose — ask your vet] (4.4 lb) less.
Health: A 2022 UK study of veterinary records found the breed to have a life expectancy of 11.33 years, slightly below the life expectancy of crossbreeds: 11.82 but just above the overall average of 11.23 years. A 2024 UK study found a life expectancy of 12 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds.
A UK study found a predisposition to juvenile onset demodicosis in the Staffordshire Bull Terrier: In dogs under the age of two years 2.14% of Staffords had demodicosis compared to 0.48% overall. An American study found the same predisposition with 10% of Staffords having the condition compared to 0.58% overall.
Neurological disorders identified in the breed include cerebellar abiotrophy, Chiari-like malformation, myotonia congenita and L-2-hydroxyglutaric aciduria. The Staffordshire Bull Terrier is one of the most commonly affected breeds for hereditary cataracts.
History: The unregulated breeding history and inconsistent genetic makeup of the Stafford's early ancestry have led to misconceptions about its origins. Individual types and styles of crossbred dogs varied by geographic region. For example, the progeny from one area may have a higher percentage of terrier than bulldog, whereas other reports claim that bulldog to terrier was preferred over bull and terrier to bull terrier. Dog breeders made careful selections to reinforce inheritable traits from specific dog types. Many of the mixed breed types, or mongrels that were used to create the early fighting dogs have long since evolved and stabilised into the modern purebred dogs we know today. Many of the desirable phylogenetic traits of the breed's ancestry have been preserved and further refined by selective breeding to better suit the Stafford's modern purpose as a conformation show dog, while the unwanted traits have been bred out.
