Physiological and behavioral responses of horses during police training.

The study evaluated how police horses, both experienced and inexperienced, react to different stressful simulations often experienced in police work. Measurements including heart rate, heart rate variability, behavior score, and standard police performance score were used to gauge the horses’ responses. The results suggest that police work, as represented by these tests, does not significantly stress horses and does not negatively impact their welfare.

Research Methodology

• The study involved 12 police horses, with half having experience and the other half being inexperienced in police work.
• The horses underwent four different tests designed to simulate various stressful situations encountered in normal police work. These tests included an outdoor track test, a street track test, an indoor arena test, and a smoke machine test.
• Four key metrics were collected during each test – heart rate (HR), heart rate variability (HRV), behavior score (BS), and standard police performance score (PPS).
• The tests were run at three different times over a 7-week period to measure any changes or trends in the data.
• Statistical analysis was performed using a linear mixed model and logistic regression.

Study Findings

• The heart rate of the horses increased significantly during the indoor arena test and the smoke machine test compared with the other two tests.
• Heart rate variability was notably lower during the indoor arena test, suggesting that this test may have been more stressful for the horses.
• The behavior scores did not show significant differences between the tests, and there was no consistent correlation between the heart rate and behavior score.
• There were no differences in the key metrics between test repetitions, indicating no habituation (adaptation to the stressful situation) occurred over the course of the study.
• No significant differences were found between experienced and inexperienced horses. This suggests that the coping mechanisms and stress levels are similar across both groups when facing these specific tests.

Conclusions and Implications

• The study found little evidence of significant stress in horses during the police training simulations.
• Although the heart rate varied among the four tests, the behavior scores remained relatively consistent, indicating only modest behavioral responses overall.
• Heart rate data may provide additional information for evaluating individual horse welfare and responses.
• The results suggest that police work, at least as represented by these tests, is not overly stressful for horses and does not appear to detrimentally affect their welfare.
