The breed is bold, fearless and devoted to its own household, but strongly territorial and suspicious of strangers. It is independent and decides for itself what counts as a threat, a trait suited to dogs left to guard flocks without close direction.
It is a massive, heavy-boned dog with a broad head and deep chest. The coat is dense with a plentiful undercoat, and its length varies; long-coated dogs carry a mane, feathered ears and a bushy tail. Grey, fawn, red and white are common, and piebald or brindle dogs also occur. In its country of origin the ears have traditionally been cropped.
The Caucasian Shepherd Dog, known in Russian as the Caucasian Ovcharka, took its modern form through Soviet kennels in the twentieth century, which drew on dogs from Georgia, Armenia, Azerbaijan and the North Caucasus. Breeders favoured the heavier, longer-coated mountain type, and the state used the breed widely as a guard for military sites, prisons and borders. It was later also bred in East Germany. Its work was protection rather than herding: it stayed with livestock and drove off wolves and intruders.
