The Therapeutic Benefits of Companion Animals


Pets have the ability to enhance your life, but they also carry significant responsibilities.

Dawn McGrath has experienced the life-changing effects pets can have. Encountering people walking their dogs can lead to conversations, alleviating stress and feelings of isolation.

“I visit teams with our dogs, Bailey, a Shetland sheepdog, and Ginger, a cocker spaniel, to local nursing facilities, rehabilitation centers, hospitals, schools, and libraries,” McGrath, a certified animal therapy volunteer, shared with The Epoch Times via email.

“This results in genuine smiles, open arms, and hugs, all of which lead to enhanced attitude, motivation, and overall joy.”

Around half of U.S. households have a pet, indicating that pet ownership brings significant joy to many. But do pets really have therapeutic benefits?
A 2018 Washington State University (WSU) study published in MDPI showed that participating in a dog therapy program improved the mental health of first-year college students. While some evidence suggests pets enhance physical and mental health, other research has yielded mixed results. Despite the lack of conclusive scientific evidence regarding the therapeutic advantages of pets, there is a wealth of anecdotal evidence supporting their value.
For those capable of safely interacting with and caring for pets, the advantages of having a loving cat or dog are numerous.

Potential Benefits for College Students

Mental health issues among college students are increasingly common globally, with a survey by the World Health Organization indicating that 35% of students screened positive for at least one common mental disorder. This concern is compounded by the emotional effects of separating from childhood pets, which can strip away a coping mechanism.

The MDPI study included 145 individuals who had left a pet at home when attending college. Participants were randomly divided into two groups: one received seven sessions of a drop-in dog therapy program, while the other was placed on a waitlist. Each session included petting, sitting with, and interacting with dogs in a casual environment.

Tracking participants’ well-being throughout the semester revealed that those in the dog group showed significantly reduced levels of anxiety, depression, and stress compared to those in the control group. Although the dogs played an essential role, the researchers noted that the calming environment and social interaction with other students and handlers also contributed.

“This is a relatively straightforward, cost-effective way to enhance student well-being,” stated coauthor Patricia Pendry, a WSU professor of human development, in a press release.

Benefits to Physical Health

Dogs often encourage owners to engage in physical activity, making them perfect exercise companions. The health benefits of regular exercise are well documented, contributing to better cardiovascular health and overall well-being.

A 2019 study published in Scientific Reports surveyed 191 dog owners, 455 non-dog owners, and 46 children in the UK during the summer of 2015. The findings indicated that dog ownership correlated with increased recreational walking and significantly greater adherence to physical activity guidelines. Additionally, children with dogs walked more than those without.
The Centers for Disease Control and Prevention (CDC) advises that adults engage in 150 minutes of moderate-intensity exercise per week, which can be split into 30-minute sessions over five days.
According to a systematic review and meta-analysis featured in Circulation: Cardiovascular Quality and Outcomes, dog ownership was linked to enhanced cardiovascular health. This review included studies from 1950 to 2019, covering data from roughly 4 million people. Some studies indicated that dog ownership was associated with lower blood pressure, improved cholesterol levels, and lessened stress responses from the sympathetic nervous system.

Overall analysis showed that dog ownership was correlated with a 31 percent lower risk of cardiovascular mortality. The authors suggested that this increased longevity may be partly due to the extra physical activity involved.

Mental and Psychological Health Benefits

The mental and psychological advantages of pet ownership are diverse, encompassing stress reduction and improved mood.

“Pet ownership leads to a decrease in cortisol, the key stress hormone,” shared Shebna N. Osanmoh, a certified psychiatric nurse practitioner at Savant Care Inc., in an email to The Epoch Times.

To back his claim, he references a 2019 clinical trial published in Sage Journals involving 249 college students.

The study divided participants into four groups: direct contact with pets, observing other pet interactions, viewing a slideshow of pets, and a control group. In the hands-on group, petting a cat or dog for 10 minutes lowered cortisol levels and provided immediate stress relief, he explained. 

Animals possess a unique ability to uplift mood and enhance mental wellness, according to Dr. Michael S. Valdez, a medical director at Detox California.

“The genuine bond formed with pets, coupled with their playful antics and affection, fosters the release of serotonin and dopamine—both neurotransmitters linked to relaxation,” Valdez stated in an email to The Epoch Times.

Beyond promoting relaxation, interactions with pets can lessen symptoms of anxiety and depression, while also helping to regulate blood pressure. Engaging with animals has been shown to mitigate stress and enhance overall well-being, he noted.

Additionally, pets can provide emotional support in mental health therapy.

“I have witnessed remarkable transformations in people due to animals,” shared Annalisa Smithson, founder and director of Unleashed Counseling, in an email. “My team works with individuals who have trouble with traditional talk therapy. Our clients report reduced anxiety, overcoming depression, and dealing with trauma through interactions with our dogs and rabbits.” Smithson noted that clients often feel more comfortable and open to sharing their emotions more quickly than they would in more conventional therapy settings.

Social Health Benefits

While pets do not replace human companionship, they can serve as a bridge to it.

“Having a dog creates natural opportunities for social interaction,” Melissa Legere, a licensed marriage and family therapist and clinical director for California Behavioral Health, informed The Epoch Times via email.

“For instance, walking a dog often leads to friendly exchanges with neighbors and other pet owners in the park. It’s an effortless way to meet new people, taking the pressure off social interactions. Plus, people tend to be more welcoming when accompanied by a dog—it serves as an immediate conversation starter.”

Even though dog walking naturally facilitates socializing, the idea of making new friends can still appear daunting.

Stephanie Boucher, a registered psychotherapist and founder of The Mindful Loft Betrayal Trauma and Relational Recovery Centre Ontario, stated that dogs can help alleviate this concern, providing emotional comfort and support. This encouragement can empower individuals to step outside their comfort zones and engage in social environments, she explained in an email.

“The bond with a pet can instill the requisite confidence in older adults living alone with few social connections, encouraging them to take social risks,” Boucher noted. “This may result in new relationships and friendships.”

Alternatives to Pet Ownership

>Not everyone has the time, financial resources, or health conditions to accommodate full-time pet ownership. Beyond pet visitation programs like the one discussed in the MDPI study, various alternatives provide part-time companionship. For those who work outside the home, hiring pet sitters or dog walkers allows for responsible pet care without full ownership, offering companionship to both the pet and the caregiver.

Fostering pets presents another option. Twila McGee, CEO and founder of NOLAs Finest Pet Care LLC, stated that fostering can be an excellent method to enjoy the benefits of being a pet parent while alleviating financial pressures.

“This approach provides pets with a loving temporary home, ensuring they receive care while waiting for permanent families. It offers an experience that’s hard to replicate in a shelter,” she explained. “When you take care of a foster pet, you’re not alone; your local shelter or rescue will provide essential resources like food, training, and medical care. I also advise fostering to those contemplating adopting a cat or dog but unsure about their readiness.”

Risks Associated with Pet Ownership

While there are many therapeutic advantages tied to pet ownership, certain risks exist as well. The main concern is the potential transmission of zoonotic diseases—infectious viruses, bacteria, fungi, and parasites that pets can spread to their owners. These illnesses can range from mild to severe and, in some cases, may be fatal, as highlighted by the CDC.

Such infections can be transmitted through direct contact with a pet’s bodily fluids or indirectly via handling pet food and water dishes. Those particularly at risk include:
  • Children under 5 and adults over 65
  • Pregnant individuals
  • People with compromised immune systems

If you have any doubts about your capability to own a pet for any reason, it is advisable to consult your physician.
