During the activities, participants wore headsets that detected brain waves and filled out questionnaires detailing their emotional states afterward.

Researchers discovered that when playing with Aro using sound-producing toys or taking him for a walk along a park path, participants’ alpha brain waves, indicating stability and relaxation, were more pronounced. This suggests an increased sense of rest and relaxation.

Engaging with Alo, brushing, and giving gentle massages to the dog strengthened beta brain waves associated with attention and concentration. This indicates improved concentration without added stress.

After completing all eight activities, participants reported feeling less stressed, tired, and depressed.

Studies have shown that activities like massaging Aro, offering treats, and hugs can enhance people’s moods. Participants also felt more at ease and relaxed while walking and massaging the dog.

“This study illustrates that certain activities with dogs can boost relaxation, emotional stability, alertness, concentration, and creativity by stimulating increased brain activity,” said Yoo. “Interacting with dogs can reduce stress and evoke positive emotional responses.”

Past studies indicate that dogs may help alleviate symptoms of depression and post-traumatic stress disorder, although the efficacy of the intervention remains ambiguous.

A 2022 survey revealed that veterans and first responders with service dogs experienced fewer PTSD symptoms than those without. However, having a dog as a pet had a minimal impact.

A 2020 clinical trial indicated that service dogs were slightly more effective in improving PTSD symptoms in veterans compared to emotional support dogs. Regardless, both types of dogs demonstrated some improvement in PTSD symptoms.

Research also suggests that for “pet therapy” to be effective, individuals must have a liking for animals.

“I was actually traumatized by dogs when I was younger, so I never fully embraced them to know if I would feel the same level of comfort,” stated Kathryn Magruder, a professor of psychiatry at the university and author of the 2020 clinical trial.

Jennifer Dobkin manages an animal therapy program called UCLA People-Animal Connection for medical patients and staff and has witnessed firsthand how interactions with dogs can aid in focus and relaxation.

“Staff members who are stressed and having a rough day visibly relax their posture. They smile. They tell us things like ‘You have no idea how much I needed this,'” she remarked.

Dobkin recounted a situation where her terrier mix dog, Toto, helped a grieving family find solace amid the sorrow and stress of losing a loved one.

Children at Stuart House in Santa Monica, Calif., also engaged with therapy dogs like a golden retriever and Labrador named North, bringing comfort and support to those coping with traumatic experiences.

“Our dogs are present to help children navigate discussions about extraordinarily stressful events they have endured. I believe it aids in concentration and provides a sense of comfort,” Dobkin concluded.
