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")
Dog breeding this change in breeding goals is the pronounced sloped back in the modern German Shepherd breed, compared to the straight back of working pedigrees. The Shar Pei is an example of how differing breed standards can influence the direction breeders take a dog and which traits are exaggerated. The Western Shar Pei has been bred to have a meatier mouth and wrinklier skin than the traditional Chinese Shar Pei it originated from. Initially, the ownership of working and purebred dogs, was a privilege of the wealthy. Today many people can afford to buy a dog. There are various reasons for
