Abstract

Coregulation is the bidirectional modulation of social partners’ physiology, including hypothalamic-pituitary-adrenal (HPA) axis activity, and it is key for forming and maintaining attachment bonds between individuals. By investigating coregulation of acute and chronic cortisol in dog-human, dog-dog...
