Diabetes Self-Management Blog

Say you were a doctor and you could only prescribe one thing, the same thing, for all your patients. What would be the most effective thing you could do for people to protect their hearts, blood vessels, and brains? Statin drugs? Nope. An exercise program? Well, that would help. But studies show that the best medicine for health is often a dog or cat.

There have been many studies. One three-year study of 5,741 people at the Baker Medical Research Institute in Melbourne, Australia, showed that pet owners had lower blood pressure, triglyceride, and cholesterol levels than did nonowners. This result held up after controlling for such personal differences as cigarette smoking, diet, weight, and socioeconomic profile.

A study at City Hospital of New York looked at ICU patients who had heart attacks or strokes. They found that only 6% of patients who owned pets died within one year compared with 28% of those who did not own pets. Pets gave a bigger survival advantage than did spouses or friends.

Just petting a dog lowers blood pressure, and the effect lasts for hours or days afterward. Other studies have found that pets reduce stress and improve depression. Just watching fish swim in a tank seems to calm behavior and lower stress in people with Alzheimer disease.

How Do Pets Help?
Pets are good for us in many ways, but a lot of them are unknown. Here’s what we do know:

  • Exercise—dogs need to go for walks, so you have to walk with them twice a day or more.
  • Regularizing your life—same thing. You need to walk them, clean up after them, feed them. Sort of like a baby, but not so demanding.
  • Social contact—going out with a pet attracts nice people into your life.
  • Stress reduction—petting an animal soothes the mind and lowers your blood pressure.
  • Unconditional love—nobody loves you like your dog does. Cats are more standoffish, but they have ways of making you feel loved, too.

What other ways have pets helped you?

Are Pets for Everyone?
You have to think about whether a pet is right for you. If you’re too disabled or too busy, you may not be able to handle a dog. Cats are easier, and smaller mammals (like rabbits or guinea pigs) seem to give some of the same benefits as do dogs and cats. Birds can be easiest of all to take care of. Their songs can raise your mood, and they’re extremely cheap to feed.

Of course, as you come to care about a pet, you leave yourself open to worry when they get sick and grief if they die. So that is a potential downside, as it is with any relationship.

The benefits seem well worth it, though. What other therapy helps your heart and your mind and licks your face, too?

  1. Dear David.

    His Lordship a Wheaten Terrier has provided all of the benefits above. This Dog does not loose any fur at all but the downside is it must be cut often by human. My wife’s barbering skills are quite good now considering it is a unwilling customer.
    Also carding it often is desirable because the fur is fine wool and does mat, however I have not been able to explain to the dog that if it put up with this it would be less itchy.
    The beast goes paranoid when left alone so people that like to travel or are othervise abscent should chose another type of dog or pet.
    Very intelligent. It is important to show the Dog that you are boss and not it, my wife head locked it to a standstill for 45 minutes the first time, then 15, 10, 5 and finally it would not struggle at all.

  2. David,

    I argue with even my best friends on occasion. I never argue with the cat. She always provides me with the ‘touch’ that I need so much (especially when my friends aren’t able to), and she has her many games she likes to play and include me in that play. I always look forward to coming home because of her.

  3. My dog makes sure I walk, comforts me when I am sad, welcomes family and friends, barks at strangers — and detects hypoglycemia! All in one furry ball of unconditional love.

  4. My dog is my alarm clock and personal trainer. Other exercise devices sit in the corner and wait till you decide to use them. A dog will not let you slack off.
