Origin of the domestic dog matched across Eurasia and its branch is phylogenetically rooted in the same sequence as the Altai dog (not a direct ancestor). The subclade d2 hybrid haplotypes are found in 2.6% of South-West Asian dogs. Haplogroup E: Derived from post-domestication wolf–dog hybridization in East Asia, (rare distribution in South-East Asia, Korea and Japan). Haplogroup F: Derived from post-domestication wolf–dog hybridization in Japan. A study of 600 dog specimens found only one dog whose sequence indicated hybridization with the extinct Japanese wolf. It is not known whether this hybridization was the result of humans selecting for phenotypic traits from local wolf populations
Small Greek Domestic Dog are often confused with the Longhaired Dachshund or a Cocker Spaniel mix. Their legs are longer than a Dachshund's which raises their belly and chest much more off the ground. The average height is around 28 centimeters. The coat of the Small Greek Domestic Dog is of three lengths, of very good quality, and is easy to groom. Sometimes, it is slightly wavy, but it should always feel silky. The coat is rich, dense and weatherproof. The sickle-shaped tail of the Small Greek Domestic Dog is usually long. The dog holds its tail up high, and has an elegant curve.
