Comparing the century-old bull and terrier to the modern Stafford, Joanna de Klerk, DVM, author of The Complete Guide to Staffordshire Bull Terriers (2019), said that “since it is so similar to the original old English bulldog, which has since been bred beyond recognition, some argue that the staffie comes exclusively from this breed rather than having a terrier in the mix.” : 8–11 Some of the confusion and misconceptions about breed is due to the breed`s inconsistent genetic makeup due to unregulated breeding practices that begin with the origins of the staffie and continue much later in its development, long before traceable pedigrees existed. It is generally accepted that Staffords descend from 19th century bulldog-terrier crosses, which were later bred for dog fighting after blood sports were declared illegal. : 8-11 But it was not until the early 20th century, long after selective breeding had refined the crosses of bulls and terriers in the later English Bull Terrier, that the Stafford finally emerged, a breed standard was created, and in 1935 the Staffordshire Bull Terrier was officially recognized by the KC. : 8–11 In the mid-19th century, the Bull and Terrier hybrids were known by various pseudonyms, such as the Patched Fighting Terrier, the Staffordshire Pit-Dog, the Brindle Bull, and the Bull-and-Terrier.  They were also called half and half, half, or more commonly bulls and terriers, although they are not real breeds in the sense that we know modern dog breeds. However, at least six modern breeds can trace their ancestry back to the crosses of bulls and terriers.  Another common name used for the bull and terrier was simply bull terrier, which became the name of the new breed developed by James Hinks. : 18 Hinks used various undocumented crosses, including Dalmatians and Collies, which followers of the original variety considered undesirable. Instead, they chose to stay true to their favorite type.   As a result, two different breeds of bull terriers emerged: the bull terrier, nicknamed the White Cavalier, and the Staffordshire Bull Terrier, named after the county where it was developed.   The bull terrier`s combative legacy was left behind, while Staffordshire Bull Terriers breeders in the UK continued their illegal competitions that coincided with what happened in the US with the American Staffordshire Terrier; Neither breed could be officially accepted in their respective countries of origin. Denise Flaim, a journalist and dog expert, summed it up in a few words: “No established registry wanted to be associated with a dog that drew blood of its own kind for a living.”  According to the RSPCA, more than a third of those killed by dogs since the introduction of the law have been attacked by legal breeds. www.heraldscotland.com/news/11923440.girl-tried-to-save-friend-from-rottweilers/ www.edinburghlive.co.uk/news/edinburgh-news/grieving-mother-11-year-old-15871676 The Animal Cruelty Act 1835 made blood sports illegal and effectively stopped the baiting of bulls and bears in Britain.  Baiting required large arenas that made it easier for authorities to control the police, while illegal dog fights were much harder to stop because the sponsors of the fight hid and strictly guarded their sites in private basements and similar locations. As a result, dog fighting continued long after the bull and bear rush stopped. It was only with the passage of the Protection of Animals Act of 1911 that organized dog fighting in Britain largely came to an end. When slavery was legalized in Brazil in the 18th century, the Fila Brasileiro was used to make fugitive slaves intact to their masters. UK law designates four specific types of dogs as dangerous and therefore makes it illegal to own, breed, sell or give them away. These are a Pit Bull Terrier, a Japanese Tosa, a Dogo Argentino and a Fila Brasileiro. When these sports were classified as inhumane and became illegal in 1835, dog fighting emerged in their place – and thus the trait of canine aggression was elevated into the genetic lineage. Will Staffordshire bull terriers be banned in the UK? It is not illegal to own and keep a Staffordshire Bull Terrier – more commonly known as “Staffy” – in the UK as the breed is not listed in the Dangerous Dogs Act 1991. The dog breeds currently illegal in the UK are the Pit Bull Terrier, the Japanese Tosa, the Dogo Argentino and the Fila Brasileiro. But crosses, including any of these types of dogs, can also be subject to the law, depending on their size and characteristics. This year, an Act of Parliament was passed banning the possession of certain types of dogs.
