The Šarplaninac or Sharr dog is a breed of dog of livestock guardian type. It is named for the Šar Mountains or Šar Planina range in the Balkans, where it is principally found. It was recognised by the Fédération Cynologique Internationale as the Illyrian Shepherd Dog or Ilirski Ovčar from 1939 until 1957, when the name was changed to Yugoslavian Shepherd Dog – Sharplanina or Jugoslovenski Ovčarski Pas – Šarplaninac.
In Ottoman times, the dogs moved with the flocks of sheep, spending the summer in the area of the Šar Mountains and the winter in Thessaly, where they were known as Greek Shepherd Dogs.
