Dog ownership lessens risk of heart disease

In a unique Swedish study, researchers found that people who owned dogs had a lower mortality rate then those who did not. They also found that people who lived alone and owned a dog had less cardiovascular diseases then people who lived alone who did not own a dog.

The researchers studied 3.4 million people between the ages of 40 and 80 making this a comprehensive comparison. What the study did not show was why there was a difference between dog ownership and non-dog ownership.

One possibility considered was that people who own dogs are more active because they walk their dogs. There was also no indication as to whether or not there were other factors such as the type of people who own dogs vs those who do not.

However, the bottom line is that dog ownership, again, has proven to benefit the health of their owners. It would be interesting to study how growing up with a dog or pet affects the health of children as adults if they continue to own a pet vs those who get a dog or pet later in life. We know that children who own pets are less prone to developing allergies. It would be interesting to know what other physical and mental benefits pet ownership has on children.
