The Effect of Dog Videos on Subjective and Physiological Responses to Stress

Abstract

ABSTRACT Research indicates that animal-assisted therapy programs can reduce stress responses. However, animals are not always permitted in public settings. Thus, alternative forms to the physical presence of an animal could be beneficial. The objective of this study was to determine (1) whether exposure to an active-dog video can help improve subjective and physiological responses to stress more than a tranquil-dog video, (2) whether exposure to dog videos can improve subjective and physiological stress responses more than nature videos, and (3) whether exposure to dog (and nature) videos can improve subjective and physiological stress responses more than a control video. Participants (n = 103; female = 78, male = 25) completed a stressful task and were randomly assigned to watch one of five videos: active dog (dog playing with a toy), tranquil dog (dog lying down quietly), active nature (fast-paced waterfall in a forest), tranquil nature (slow-moving stream in a forest), or blank screen (control video; a video of a black screen). Improvements in subjective (i.e., decrease in stress, anxiety, negative affect, and/or increase in happiness, relaxation, positive affect) and physiological (decrease in heart rate and blood pressure) responses to the stressor were examined. This study found no evidence that the active-dog video improved subjective or physiological responses more than the tranquil-dog video. However, this study found evidence that dog videos can decrease subjective anxiety and increase positive affect more than nature videos. Similarly, this study also found that dog videos can decrease subjective anxiety and increase happiness and positive affect more than can the control video. The effects of the dog videos and nature videos (and control video) on the remaining subjective measures and all physiological responses did not differ. Together, the results show some evidence that dog videos may be better at improving subjective anxiety, happiness, and positive affect responses than nature and/or control videos. However, the results did not show evidence that dog videos could alleviate any physiological responses more than the other videos. Practical applications of these findings include how to improve subjective anxiety and affect responses in public settings (e.g., universities) when animals are not allowed.
