The breed is believed to have originated in Muslim Spain and was used to hunt rabbits and other small game on the Balearic Island of Ibiza. The Ibizan Hound is a fast dog that can hunt on all types of terrain, working by sight, sound, and scent. Spanish hunters run these dogs in mostly female packs, with perhaps a male or two, as the female is the better hunter. This breed is similar to the Pharaoh Hound, but the Ibizan Hound is larger and can have a multicolored hair pattern.
