The Kerry Beagle is one of the oldest Irish hound breeds, believed to be descendant from the Old Southern Hound or the Celtic Hounds. It is the only extant scent hound breed native to Ireland. It is unclear why the name 'beagle' has been applied, as the Kerry Beagle is a medium-sized hound; height is between 56–61 cm (22–24 in), weight is up to 27 kg (60 lb), sharing little in common with the Beagle. The Kerry Beagle has a broad head, a short coat, and long ears, black, and tan is the more common color but the coat may be tan and white, blue mottled and tan or black. The breed's looks suggest speed and endurance.
