The best way to stay healthy and lose weight is to own a dog and make sure to take it on regular walks.

The researchers also found that while younger dog owners managed to get the most benefits from taking their dogs to walks, middle age people had the least amount of time for such walks.
“Obviously you would expect dog walkers to walk more, but we found people who walked their dog also had higher overall levels of both moderate and vigorous physical activities. There appears to be a strong link between owning and walking a dog and achieving higher levels of physical activity, even after accounting for the actual dog walking”, lead researcher Mathew Reeves said.
