This is an interesting follow on from yesterday’s post.
A 2024 a study investigated whether changes in guardian stress levels influence canine stress in novel environments. The study was measured by monitoring heart rate and heart rate variability in both dogs and their guardians.
The test participants were divided into two groups: one exposed to a stress-inducing intervention (short term digit memory test) and another to a stress-relieving intervention (meditation).
The test showed that changes in guardian heart rate significantly predicted changes in their dog's heart rate, suggesting dogs exhibit emotional contagion and social referencing towards their people.
Guardian stress levels increased significantly in the stress-induction group, whilst the meditation group showed a trend towards decreased stress. We know that meditation can relieve our stress, but now we know that by addressing our own nervous system responses we affect the physiological responses of our dogs.
Dog behaviour during the experiment correlated with their HR and HRV, the dog’s body language and their heart rate matched.
The research shows that our dogs can easily and quickly match our own stress levels. So not only can they smell our stress, but they also match it via heart rate.
The test also showed that a dog’s heart rate will settle over time, highlighting the importance of allowing dogs to acclimatise to novel situations at their pace, and not rush them through novel experiences.
We know we are connected with our dogs, but do we know how much?
Science is helping us find out.
What a wonderful evolution our species is going through.
