Dogs are the oldest domesticated animals. The process of domestication of dogs is still unclear; however, they have established themselves as human partners and are sometimes more cooperative with humans than their conspecifics. In this study, to determine the effect of affiliative human presence on group behavior in dogs, we conducted short-time trials analyzing dog group movements. There was a hierarchical relationship in which juvenile dogs were aware of adult dogs, and adult dogs were aware of human movements. We also found that the age of the juvenile dog and the characteristics of their mothers may affect the movement behavior of juvenile dogs.
