How your mental health can affect your dog

(MENAFN- Asia Times) If you think your dog looks stressed out, it might be your own stress levels that are affecting your pet pooch.

A studypublished on Thursday in Nature's Scientific Reportsshows pet dogs may synchronize their stress levels with those of their owners.

More than just being 'man's best friend," it appears our pet dogs may be mirroring our mental state too, and that can be bad for their health.

Swedish researchers studied 58 dogs – 33 Shetland Sheepdogs and 25 Border Collies – as well as their owners. The dogs selected were balanced for sex, breed and activity level.

Both dog and owner personality was assessed through standardised personality questionnaires, with owners filling out theDog Personality Questionnaireon behalf of their pet.

The researchers also measured the hormonecortisolin the hair of dogs and their owners over a year-long period.

Cortisol is a measure of physiological stress, which can be raised during mental distress. But it's also elevated for short periods such as during exercise and illness.

Hair cortisolis a good way of measuring long-term trends in stress levels, as hair grows slowly (about 1cm per month) and absorbs circulating substances from the blood.

The results showed a significant correlation between human and dog cortisol levels across the year. In 57 of the dogs in summer and 55 in winter, cortisol levels matched those of their owners. This means that for these dogs, their cortisol levels rose and fell in unison with their owner's.

This correlation was not influenced by dog activity levels or dog personality. It was, however, influenced by owner personality. Owners with higher stress levels tended to have dogs with higher stress levels too.

Female dogs had a stronger connection with their owner's stress levels compared with male dogs. Previous studies have shown that female dogs (as well asratsandchimpanzees ) are more emotionally responsive than males.

Increased interactions

There's also evidence that increased oxytocin (the love and bonding hormone) in female dogs results inincreased interactions with their owner , causing a corresponding increase in the owner's oxytocin levels. This effect wasn't seen in male dogs.

A limiting factor to the new study was that it did not identify any causes of elevated stress in the dog owners. But what it does show is that regardless of the cause of the stress, our reaction to it impacts our dogs.

Researchers have long discussed the concept of what is called the 'human-dog dyad', a close bond between humans and dogs. This relationship,developed over 15,000 years , is unique in the animal world.

There is evidence to suggestdogs evolved alongside usand consequently arein tune with our emotionsandbond with us through eye contact .

Although many aspects of this inter-species relationship are positive (particularly for us), it's likely there are some drawbacks to this close relationship with dogs.

Like many animals, we canshare diseases with our dogssuch as the superbugMRSAandQ Fever . What's more,dog bites are an issue of increasing importanceto society.

We know that failing to providing basic care like food and shelter is cruel, but we often overlook how disregarding the mental lives of our pets can also negatively impact their welfare.

Helping our dogs cope

Dogs aresentient animals . This means they can experience both positive and negative emotions, such as pleasure, comfort, fear, and anxiety.

A poor mental state, where a dog is regularly experiencing negative emotions such as anxiety,can lead to poor animal welfare . If owners have an impact on the stress levels of their dogs, it means we also play a role in protecting their welfare.

The impact we have on our dog's stress levels goes both ways - positive and negative. If we reduce our own stress levels, it's likely we will also reduce our dog's stress levels.

We know chronic stress is bad for bothhumansanddogs , increasing the likelihood we will get sick as well as decreasing our quality of life.

If you don't work on decreasing your stress levels for your own sake, perhaps you will do it for your dog. There aregreat resources availablefor decreasing stress levels, and the good news is that some of them, such asgetting out in nature , can be done with your dog right by your side.
