The earliest-known record of a rat-catching dog is that of "Hatch", whose remains were recovered from the Mary Rose, the flagship of Henry VIII, sunk in 1545 and raised in 1982. Hatch is thought to have been a mongrel, and was brought on board to control the rat population. One source claims that during a competition in England, a single terrier killed 2,501 rats over a seven-hour period in a rat-infested barn an average of one rat every ten seconds.
