Salivary Cortisol variability is influenced by social characteristics of owner and dog

Psychobiological Factors Affecting Cortisol Variability in Human-Dog Dyads Author: Schöberl I, et al. (2017), PLOS One Stress responses within dyads are modulated by interactions such as mutual emotional support and conflict. We investigated dyadic psychobiological factors influencing intra-individual cortisol variability in response to different challenging situations by testing 132 owners and their dogs in a […]
