If you’re a dog lover like me, you know how beneficial a pet dog can be. Dogs give us unconditional love and companionship, and help us reduce stress, stay active and be socially connected.

What you may not know is that our four-legged friends can also help us feel less pain. In fact, according to a new study, they’re better at it than humans.

A team of European researchers conducted an unusual experiment to see if people experience less pain when their dog was nearby or when they were with a close friend.

They recruited 124 healthy female pet owners to immerse their hands in cold water (about 36°F) for up to five minutes to induce pain. The so-called “cold pressor task” is a common way for researchers to induce acute pain in clinical studies.

For this study, the cold water test was performed in a laboratory while the participants had either their pet dog or a same-sex friend nearby. Some of the women took the test while alone and served as a control group. The interaction of the participants, dogs, and their friends was monitored by video camera.   

The study findings, recently published in the journal Acta Psychologica, suggest that dogs can help people cope with painful situations better than humans can.

“Participants reported and showed less pain and they felt less helpless in the dog condition compared to the alone condition,” wrote lead researcher Heidi Mauersberger, a Research Assistant in the Department of Psychology at Humboldt University in Berlin.

“Participants accompanied by their dog reported less pain and showed lower physiological pain reactions, greater pain tolerance, and less intense facial displays of pain as well as felt less helpless than participants…accompanied by their friends.”

Being with a friend was better than being alone, but Mauersberger says the presence of another human being -- even a close friend -- made the women feel like they were being judged or evaluated.

“In contrast to the presence of pet dogs, the mere presence of close friends may have triggered social demands and social-evaluative threat in the painful situation. In fact, the increased eye contact frequency between participants and friends compared to participants and dogs may be a reason for the heightened threat perceptions in the friend compared to the dog condition.”

To test their theory further, researchers conducted a second test, this time immersing the participants’ hands in cold water while they were with a complete stranger or a dog they were unfamiliar with.

The results were largely the same. The pet owners felt more comfortable and coped better with pain around dogs they had not bonded with. Individuals with positive attitudes about dogs experienced the most pain relief.

“Participants demonstrated better adaptation to pain, exhibited less pain behavior, reported reduced helplessness and higher self-efficacy as well as experienced more positive affect when suffering pain in the presence of unfamiliar dogs compared to the presence of unfamiliar human companions,” said Mauersberger.

To be clear, this experiment wasn’t designed to come up with another wacky treatment for chronic pain. People with chronic pain or taking prescription medication were excluded from the study.

The research was conducted to help demonstrate the value of therapy dogs, which have long been known to provide psychological benefits to people suffering from stress, anxiety or loneliness.

A 2020 study helped explain how that happens. People being treated for fibromyalgia who interacted with a therapy dog had a significant increase in levels of oxytocin – a hormone released by the pituitary gland that’s known as the “cuddle hormone” or “love hormone.” They were also more relaxed, their heart rates slowed, and they had more positive thoughts and feelings.  

Do you have a dog, cat or pet of any kind that helps you feel better?
