Impact of Interactions with a Puppy and Handler Versus a Handler Alone on Stress and Vitality in a University Setting: A Crossover Study

Brief interactions with a well-behaved dog can enhance wellbeing, but most campus-based dog visitation programs employ adult, trained dogs. There is little research about the impact of puppies on wellbeing or stress in this context. The aim of this study was to examine changes in perceived stress and vitality after interacting with a puppy. Staff and students (<i>N</i> = 32) at an Australian university attended the campus on two occasions, one week apart, as part of a crossover design. Participants were pseudo-randomly allocated to a group whereby they spent 20 min interacting with a handler alone at Visit 1 and interacted with a puppy and handler at Visit 2, or another group which reversed the interaction order. Perceived stress and subjective vitality were measured before and after each interaction. The increase in vitality was greater in the group experiencing the puppy and handler interaction first (significant main effect, <i>F</i>(1,49) = 646.89, <i>p</i> = 0.024, η²_p = 1.00), regardless of the visit, possibly due to a social lubricating effect by the puppy, which carried over to the 'handler alone' second visit. Reductions in perceived stress were greater after the interaction with the puppy, for both groups (significant interaction effect, <i>F</i>(1,49) = 5.13, <i>p</i> = 0.029, η²_p = 0.11), indicating that the puppy's presence can reduce stress more than the handler alone. This extends the evidence for university-based dog-facilitated wellbeing programs, by showing that interactions with puppies can also be effective. This is important as it may mean that puppies already on campus as part of a socialization/training program can be incorporated into wellbeing programs for staff and students.
