It was a certain James Hinks who first standardized the breed type in the 1850s, selecting the egg-shaped head. The breed was first shown, in its current form, in Birmingham in 1862. The Bull Terrier Club was formed in 1887. One really interesting thing about the breed is that the pattern deliberately says: “there are no limits on weight or height. , but the dog must give the impression of maximum substance for its size, consistent with its qualities and sex. The dog must be balanced at all times”.

Minor examples of the Bull Terrier had been known since the early 19th century, but lost popularity before the First World War and were removed from the breed’s Kennel Club records in 1918. In 1938, a breed recovery was headed by Colonel Richard Glyn and a group of enthusiastic friends who founded the “Miniature Bull Terrier Club”. The standard is the same as the Bull Terrier, except for the height limit.
