A neighbor stopped by this morning. “Are you training Sasha to be a therapy dog?”

“No,” I responded. “But she’s certainly good therapy for me!”

Sharing your life with a dog really is good for your health and overall well-being. Consider, for example, this info from Harvard Healthbeat:

Pet ownership, especially having a dog, is probably associated with a decreased risk of cardiovascular disease. This does not mean that there is a clear cause and effect relationship between the two. But it does mean that pet ownership can be a reasonable part of an overall strategy to lower the risk of heart disease.

Several studies have shown that dog owners have lower blood pressure than non-owners — probably because their pets have a calming effect on them and because dog owners tend to get more exercise. The power of touch also appears to be an important part of this “pet effect.” Several studies show that blood pressure goes down when a person pets a dog.

There is some evidence that owning a dog is associated with lower cholesterol and triglyceride levels. A large study focusing on this question found that dog owners had lower cholesterol and triglyceride levels than non-owners, and that these differences weren’t explainable by diet, smoking, or body mass index (BMI). However, the reason for these differences is still not clear.

Dogs’ calming effect on humans also appears to help people handle stress. For example, some research suggests that people with dogs experience less cardiovascular reactivity during times of stress. That means that their heart rate and blood pressure go up less and return to normal more quickly, dampening the effects of stress on the body.

If circumstances limit your ability to share your own home with a dog, consider volunteering at your local shelter. Visit Adopt-A-Pet online or Volunteer Match to find opportunities near you.
