The aim of this study was to investigate the physiological effects of the relationship between dog owners with neuroticism and their dogs using noninvasive procedures to measure urinary cortisol and heart rate variability (HRV). Owner personalities were tested via the NEO Five-Factor Inventory and this study focused only on the dimension of neuroticism with 12-item scales. The 24 participating owners and their dogs were randomly divided into experimental and control groups. Each participant and their dog stayed in the test room for 80 minutes. The behavioral test included 2 resting times (R1 and R2, respectively), 2 command-communication times, a separation time, and a free time. In the control group, the command-communication times were changed to noncommunication times. Each participant wore a chest heart rate transmitter and a wrist watch monitor (RS800CX; Polar Electro) during the experiment. HRV is a quantitative parameter of autonomic activity. The spectral analysis of HRV is divided into 2 major oscillatory components: the high-frequency (HF) domain, which reflects parasympathetic activity and the low-frequency (LF) domain, which reflects both sympathetic and parasympathetic activities. The LF to HF ratio reflects sympathetic activity. In the experimental group, the neuroticism scores showed a positive significant correlation with a change in the HF power and a negative correlation with the ratio of the change in the LF to HF ratio. No correlations were found in the control group. Next, all participants were divided into 2 groups according to the HRV in R1 and R2. One group included participants whose HF increased in R2, and the other included participants whose HF decreased in R2. The neuroticism scores were significantly higher in the experimental subjects whose HF increased in R2 than in those whose HF decreased in R2. High neuroticism scores indicate individuals that may be sensitive to daily stresses. Our results showed that a parasympathetic activation occurred in owners with high neuroticism scores 10 minutes after a command-communication interaction with their dogs. This suggests that daily command communication based interactions with their dogs could improve the owner's health for the better. (C) 2014 Elsevier Inc. All rights reserved.
