They say a dog is man’s best friend, but research suggests having a pet dog may be good for your heart, too.

Studies have found that pet ownership may help lower the risk of death from cardiovascular disease, reduce blood pressure, and even improve recovery after a heart attack or stroke.

The simple act of petting a dog creates a physiological response that prompts the release of serotonin and oxytocin, the “feel good chemicals,” which help lower stress levels, decrease anxiety and lower blood pressure, said Elizabeth Hill, LCPC, ATR-BC, licensed clinical professional counselor at Endeavor Health Behavioral Health.

She’s seen the calming effect a dog can have in therapy sessions, with a patient in crisis, or in her own daily life.

“You instantly feel a sense of calm and even joy when you are connecting with an animal,” said Hill, who is a dog owner.

Health benefits of owning a dog

While a causal relationship between pet ownership and better heart health hasn’t been found, studies suggest pet owners may reap several health benefits, including:

  1. More physical activity. Studies have found that dog owners report more exercise each week, likely because of regular walks. The American Heart Association recommends at least 150 minutes of moderate physical activity each week.
  2. Lower stress levels. Research shows that pet owners, particularly cat or dog owners, may respond better to stress than those without pets. One study found interacting with dogs lowered stress levels among university students.
  3. Better outcomes for people with cardiovascular disease. One study of patients with established cardiovascular disease found that those who had pets, particularly dogs, had a higher survival rates than those who did not own pets.

Although many studies have focused on dogs for their potential to be beneficial to heart health, Hill notes that any pet can help with overall health.

“It doesn’t have to be a cute, fluffy puppy or cat, just an animal someone feels a bond with,” she said.

While pet ownership may offer many health benefits, it shouldn’t replace regular checkups with your primary care physician. Knowing your numbers — blood pressure, cholesterol, blood sugar levels — can help you and your doctor prevent or manage disease as you age.

Hill also suggests exploring your options and making sure pet ownership is the right fit for your lifestyle before making the commitment. If pet ownership isn’t feasible, volunteering at a nearby animal shelter could also be an option and be a great help to the community, she said.

Endeavor Health runs a popular Animal-Assisted Therapy (AAT) program with dogs at Endeavor Health Edward Hospital in Naperville, Endeavor Health Elmhurst Hospital and Endeavor Health Northwest Community Hospital.

Studies have shown that patient interactions with a therapy dog had a significant positive effect on their mental state. Endeavor Health’s therapy dogs and their owners love volunteering to bring joy to patients and visitors alike.
