The Caucasian Shepherd Dog (Georgian: კავკასიური ნაგაზი; Russian: Кавказская овчарка, romanized: Kavkazskaya ovčarka; Azerbaijani: Qafqaz Çoban iti) is a large livestock guardian dog breed from the Caucasus Mountains, commonly bred in the mountainous regions of Transcaucasia, especially in Georgia. It is a low-activity dog, seemingly lethargic when not working, but noisy and intimidating when it feels its family is threatened. Although certain strains are more vicious than others, they are often very territorial and aggressive towards other dogs, needing early and careful broad socialization, as well as consistent, but never forceful, handling. This breed can be a good family-dog, if it is well-trained and socialized. 6 Famous Owners.
