Commentary: Are you stressed? Your dog can tell

Your personality can affect the stress level of your dog, says Keele University's Jan Hoole.

KEELE, England: Stress is an unavoidable component of modern life. 

Many people worry about the effect of a stressful lifestyle on their long-term health, but how many of us think about how our lifestyle, and our own stress levels, affect the health of our pets? 

A new study in Scientific Reports suggests that we should be paying more attention to this, since long term stress in dog owners shows a correlation with long term stress in their dogs.

The authors of the study, a team of scientists based in Sweden, looked at levels of the stress hormone cortisol, by analysing hair samples from 58 dogs and their owners.

The results were fascinating, and complex. 

For example, it appears that the personality of the owner can affect the stress levels of the dog, but not the other way around. 

That season affects the cortisol levels of both breeds of dog, being higher in the winter. That training and activity levels did not affect the cortisol levels of the dogs, but that competing dogs had lower cortisol levels in the winter than pet dogs.

One of the most interesting results is that owners with higher stress levels had dogs with higher stress levels in both winter and summer. The authors suggest that this is a causal effect, that dogs are responding to stress levels of their owners.

Recent work is suggesting that this is a completely false perception and that animals as diverse as goats, horses and dogs can not only feel emotions but perceive and respond to them in others.

Given that fact, it is certainly possible that dogs are perceiving and responding to their owners’ stress. 

The authors of this study imply that this is the case, but do not appear to have enquired about shared life events, such as bereavement, ending relationships, moving house, changing routine through the owner changing employment, or other aspects of life that might have made both dog and owner feel stressed, independently of how the other is feeling. 

However, it would be almost impossible to measure the effects of these events on each partner independently of the other, since they are, by definition, closely shared.

Personality traits such as being conscientious seemed to correlate with more stress in dogs, particularly for male dogs, while the owner having a self-declared neurotic personality was related to lower stress levels in male dogs, but higher ones in female dogs. 

It is suggested that the reason for the differing effects of neuroticism may be that females of many mammal species are more responsive to the emotions of others, causing the female dogs to be directly affected by the owners’ anxiety levels.

On the other hand, neurotic and anxious people tend to make stronger bonds with their pets, often using them for emotional support, and this may make male dogs feel more secure and therefore less stressed.

It is a little more difficult to see the connection between being conscientious and having a more stressed male dog, but it probably depends on the form that the trait takes. 

For example, a person who is more conscientious about their work may have less time to spend with the dog and therefore a less strong bond.

One who tries to be more conscientious about how they look after the dog may have more rules and be less flexible about allowing the dog to have some freedom of choice in its life, which can be a factor in increased stress levels, but it is impossible to draw conclusions without a more detailed definition of “conscientious”.

Dog owners should take particular note of this study and consider how their own lifestyle and relationship with their dog may affect the mental well-being of both.

Although there are still many questions to be answered about the causal relationships between owner stress levels and dog stress levels, it is clear that they are not independent of each other.

If we are going through particularly stressful life events we may need to try to find ways to reduce the impact on our faithful canine companions.
