Framed by the isolation of the pandemic, loneliness has become a huge concern across the world in recent years. Loneliness is considered as harmful as smoking 15 cigarettes a day and may be a greater public health threat than obesity.
Long known as man’s best friend, dogs are being embraced even more now as a means of combatting loneliness. In one study, frequent interactions with dogs, either through ownerships or through long-term interventions, have been associated with positive psychological outcomes across the human lifespan.
“They are skilled at socializing with humans, sensitive to our emotional states and gestures – they can communicate using complex cues and form complex attachment relationships with humans,” said Nancy Gee, Ph.D., C-AISS, professor of psychiatry and the director of Virginia Commonwealth University’s Center for Human-Animal Interaction and Bill Balaban Chair in Human-Animal Interaction. “Their attachment to their human owners mirrors that of human babies to their mothers.”
Gee, whose been studying the relationship between therapy dogs and humans for more than two decades, spoke with VCU Health News about how interactions with dogs can relieve loneliness and increase connection with others.
How can dogs combat human loneliness?
Dogs are thought to fulfill the four roles of an attachment figure: They are enjoyable, comforting, missed when absent and sought in times of distress. Adults and children alike confide in their pets because they relieve us from the worry of confidentiality, judgments, or meeting expectations.
Dogs are known as wonderful “social icebreakers” and referred to as the “great leveler” – people will risk directly engaging with unfamiliar people when there is a dog present. Additionally, research shows that pet owners have made friends through their companion animals, which have helped them engage more in the community.
When humans interact with a dog in a calm way – where they are stroking the dog and making eye contact, or even talking to the dog – we see that both species release oxytocin (bonding/feel-good hormone), and their cortisol (stress hormone) levels drop. Additionally, their blood pressure and muscle tension lower, and their mood elevates.
When you combine these responses together, it indicates the interactions are relaxing and enjoyable, which helps to reduce a person’s overall experience of loneliness.
Is there a difference from other animals?
Probably, yes, but there is not enough research on the subject to know for certain. We do know that dogs are unique in the animal kingdom. Through domestication and selection, dogs emerged from the grey wolf over a period of at least 35,000 years, and there is probably no other species on the planet as well-matched to human social needs as dogs.
What are common types of service dogs, and do they differ in addressing human loneliness?
There are three prominent classifications:
- A Service Dog (also called an Assistance Dog) has one handler who has a medically recognized disability. The dog is specially trained to assist that one person (their handler) with some aspect of that disability. For example, some dogs are trained to alert a person with a seizure disorder that a seizure is about to occur. This will allow the person to take medicine, call for assistance and/or get into a safe place/position so that they are not harmed during the actual seizure. Service Dogs are covered under the American’s with Disabilities Act and are granted access to public facilities and housing that otherwise excludes pets.
- An Emotional Support Animal can be any animal species and requires no specific training. An ESA supports one person with a mental disability by comforting that person in a way that reduces symptoms. ESA status is determined by a mental health professional who writes a letter attesting to the animal’s role and housing status if pets are otherwise not allowed. However, ESAs are not permitted any other public access.
- A Therapy Dog is handled by one person, but the dog’s job is to interact with many people who may benefit from the interaction. Therapy dogs, like those in our center’s Dogs on Call program, are granted access to facilities and transportation based on the permission of the administration of the facility or transportation provider, and the requirements of the program in which the dogs participate.
Currently, there is very little research that compares the three classifications of animals and the effects of SDs or ESAs in reducing loneliness. However, Dogs on Call specifically, and other therapy dogs in general, have been found to significantly reduce loneliness in the people they visit.
Does human age matter in regard to loneliness and the benefits of interacting with dogs?
We have results back from our own randomized clinical trials showing that for older adults and for adults with mental illness, interacting with Dogs on Call dogs and handlers is effective at reducing loneliness.
We’ve just completed data collection on our pediatric study, so we don’t know the answer just yet, but we have reason to believe that across the human lifespan, interacting with a therapy dog can reduce loneliness. Additionally, one study showed that adolescents derive more satisfaction from, and engage in less conflict with, their pets than with their human siblings.
How can individuals who don’t own dogs stand to benefit?
There are many ways people can benefit from dogs without all the responsibilities involved in dog ownership.
First, visit with one of our Dogs on Call dogs – they do events throughout the VCU Health system and across the Monroe Park Campus. Second, volunteer at a local animal shelter. Those dogs and cats need attention from people, and you can feel good about making a difference in their lives. Third, offer to walk or pet-sit for your friends and neighbors who have a dog or cat.
