Old English Bulldog
In England, the passage of the Cruelty to Animals Act 1835 caused a decline of bull-baiting and dog fighting, leading to a lack of interest in perpetuating the Old English Bulldog. Three dogs from the Duke of Hamilton's strain of Old English Bulldog, Wasp, Child, and Billy, were depicted in a painting and recognized as some of the last known members of the breed before it became extinct.
