Below the title in the lower margin the caption provides Billy’s pedigree and a chart of his achievements between 1820 and 1823:
Now the property of Mr. Charles Dew, bred by that well known Fancier James Yardington, he was got by Mr. Poples Billy, son of his old Billy bred by James Tattersall Esq’r. of Weetten under Edge Gloucestershire from the best Strain of Bull Dogs in England; Billy on the Bitches side was bred by Yardingtons Sall, she was bred from the Curley Strain, an extraordinary good half-bred Bitch and well known to the Fancy, and from Turpin a Bull Dog bred by J. Barclay Esq’r. of Jacklin’s Strain, the greatest Bull Dog Fancier in the World, and from Blind Turk, another famous Bull Dog, these Dogs have been traced back for these 40 years by the oldest Judges. Billy killed a number of Rats before he was known to the Sporting World and won with ease the following matches,

Some terriers, like Billy, were bred for ratting. One of his matches was reported in The Sporting Magazine, which in 1822 described him as a “famous dog…of rat-killing notoriety.” At the height of his career, Billy held a record of 3.3 seconds per rat, which stood until 1862 when a dog named Jacko surpassed it. As attitudes toward animal cruelty and exploitation of dogs evolved, the sport gradually lost acceptability. In 1835 the Parliament of the United Kingdom banned animal baiting sports with bulls, bears, and other large animal rat baiting remained legal until about 1912.
