The Caucasian Shepherd Dog or Caucasian Ovcharka is a large livestock guardian dog native to the countries of the Caucasus region, notably Georgia, Armenia, Azerbaijan, Ossetia, and Dagestan. It was developed in the Soviet Union from about 1920 from dogs of the Caucasus Mountains and the steppe regions of Southern Russia. The Caucasus Mountains in Georgia has historically been the principal region of distribution of the Caucasian Shepherd dogs, both in terms of numbers and the quality of the dogs present in the area.
