Origin of the domestic dog haplotype designated as S805 (28,000 YBP) from the Yana River was one mutation away from another haplotype S902 (8,000 YBP) that represents Clade A of the modern wolf and domestic dog lineages. Closely related to this haplotype was one that was found in the recently-extinct Japanese wolf. Several ancient haplotypes were oriented around S805, including "Canis c.f. variabilis" (360,000 YBP), Belgium (36,000 YBP – the "Goyet dog"), Belgium (30,000 YBP), and Konsteki, Russia (22,000 YBP). Given the position of the S805 haplotype on the phylogenetic tree, it may potentially represent a direct link from the progenitor (including "Canis c.f. variabilis")
Karakachan dog working purebred livestock guarding Karakachan dogs are found in Bulgaria and the United States. The Karakachan was officially approved as a Bulgarian old native breed in 2005. The Karakachan dog may be a descendant of ancient Balkan domestic dogs, possibly since the time of the Thracians. In ancient Thracian treasures, figures were found of big, longhaired guardian dogs with curled tails. The Karakachan dog is part of the origin of the Bulgarian Shepherd dog, with which it should not be confused. Bulgarian Shepherd dog is new construction result of mixing of Karakachan dogs with some big Eurasian breeds - Caucasian
