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 training questioned by many behaviourists. Dog training is teaching a response to cues or commands, or the performance of actions not necessarily natural to the dog, and also raising a dog accommodated to his environment by modifying natural digging, barking and eliminating behaviors. Dog training is defined as the purposeful changing of a dog's behavior. Dog training can be socialisation to the domestic environment, basic obedience training or training for specialized activities including law enforcement, search and rescue, hunting, working with livestock, assistance to people with disabilities, entertainment, dog sports, detection and protecting people or property.
