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.
