About 1850, James Hinks started breeding "Bull and Terriers" with "English White Terriers" (now extinct), looking for a cleaner appearance with better legs and nicer head. In 1862, Hinks entered a bitch called "Puss" sired by his white Bulldog called "Madman" into the Bull Terrier Class at the dog show held at the Cremorne Gardens in Chelsea. Originally known as the "Hinks Breed" and "The White Cavalier", these dogs did not yet have the now-familiar "egg face", but kept the stop in the skull profile.
The dog was immediately popular and breeding continued, using Dalmatian, Greyhound, Spanish Pointer, Foxhound and Whippet to increase elegance and agility; and Borzoi and Collie to reduce the stop. Hinks wanted his dogs white, and bred specifically for this. Generally, however, breeding was aimed at increasing sturdiness: three "subtypes" were recognised by judges, Bulldog, Terrier and Dalmatian, each with its specific conformation, and a balance is now sought between the three. The first modern Bull Terrier is now recognised as "Lord Gladiator", from 1917, being the first dog with no stop at all.
Due to medical problems associated with all-white breeding, Ted Lyon among others began introducing colour, using Staffordshire Bull Terriers in the early 20th century. Coloured Bull Terriers were recognised as a separate variety (at least by the AKC) in 1936. Brindle is the preferred colour, but other colours are welcome.
Along with conformation, specific behaviour traits were sought. The epithet "White Cavalier", harking back to an age of chivalry, was bestowed on a breed which while never seeking to start a fight was well able to finish one, while socialising well with its "pack", including children and pups. Hinks himself had always aimed at a "gentleman's companion" dog rather than a pit-fighter—though Bullies were often entered in the pits, with some success. Today the Bullie is valued as a comical, mischievous, imaginative and intelligent (problem-solving) but stubborn house pet suitable for experienced owners.
