The Greek Shepherd or Greek Sheepdog (Greek: Ελληνικός Ποιμενικός, Ellinikós Pimenikós) is a breed of livestock guardian dog from Greece. Thought to be ancient in origin, the Greek Shepherd is very closely related to livestock guardian dog breeds from neighbouring countries; it is believed that some dogs are simultaneously claimed to be other breeds as they migrate annually across national borders with the flocks they protect in search seasonal pastures. The Greek Shepherd is a large breed of dog that closely resembles the Italian Maremmano-Abruzzese Sheepdog, the Hungarian Kuvasz and the Polish Tatra Shepherd Dog; the breed displays the traits common to most livestock guardian dog breeds, including a thick weatherproof double-coat and a powerful build. The Kennel Club of Greece's breed standard states dogs should stand over 66 centimetres (26 in) at the withers and that they can stand as much as 70 to 75 centimetres (28 to 30 in) tall; and that bitches should be over 60 centimetres (24 in) tall but can attain heights of 65 to 68 centimetres (26 to 27 in). The breed standard states dogs should weigh between 40 and 55 kilograms (88 and 121 lb) and bitches between 32 and 40 kilograms (71 and 88 lb). (Source: Wikipedia.org, CC BY-SA)
