Pet dogs: Does their presence influence preadolescents' emotional responses to a social stressor?

Despite interest in human-animal interaction, few studies have tested whether the presence of a dog facilitates children's emotional responding. Preadolescents (N = 99) were randomly assigned to complete the Trier Social Stress Test either with or without their pet dog. Children rated their positive and negative affect, and high-frequency heart rate variability (HF-HRV) was assessed throughout the session. Children reported higher positive affect when they completed the task with their pet dog, although there were no differences for negative affect or HF-HRV. Children who had more physical contact with their dog at baseline reported higher positive affect. The findings suggest contact with pets is associated with enhanced positive affect.
