Snap was a Thoroughbred racehorse who won all four of his races. After retiring from racing he became a successful stallion. He was Champion sire four times and his progeny included the undefeated Goldfinder.

The title of champion, or leading, sire of racehorses in Great Britain and Ireland is awarded to the stallion whose offspring have won the most prize money in Britain and Ireland during the flat racing season. The current (2022) champion is Dubawi, who earned his first title after finishing runner-up multiple times.
