The Positive Effects of Interacting with Dogs


To conduct this study, researchers used an electroencephalogram (EEG) to measure brain waves. A total of 30 adults participated in the study by first resting and staring at a wall for a few minutes and then interacting with Aro, a 4-year-old poodle. This allowed the experts to monitor what was going on in the brains of the participants during various interactions with the dog, and it helped them see how their brains changed as a result of being with Aro.  


The participants engaged in eight different activities with Aro to see how each one would affect the brain. The activities were meeting, feeding, playing, grooming, massaging, walking, hugging, and photographing. In addition to having their brains monitored during each activity, participants filled out a survey after each activity to talk about the emotions they experienced.


The fascinating findings from the study showed that people felt better after they interacted with Aro. They were more energized, less stressed, and happier, and also experienced greater concentration and relaxation, with an improvement in their mood.


More Specific Insights Than Previous Research


Prior research found that dogs can have myriad effects on people, but this study shows how the brain itself changes when you interact with a canine companion. For example, alpha brain waves strengthened when playing with and walking with Aro, while beta brain waves were stronger when playing with, massaging, and brushing her.  


Alpha brain waves are associated with relaxation, and beta brain waves are associated with concentration. Playing with Aro boosted both.


Whether they were giving Aro treats, taking her for a walk, hugging her, or any of the other eight activities, the participants experienced positive changes in how they felt because of the changes in their brain wave activity. Therefore, this research helps to further prove just how amazing dogs are, and the impact that they can have on our emotional and mental well-being.
