As a dog lover and owner, I didn't need to read this recent study demonstrating that dog owners often fulfill the recommended 150 minutes of moderate exercise per week just by walking their dog. But this study showed more than just that. The researchers found that the dog owners were also more physically regardless of time spent with their pet. Possibly another example of movement begets movement, or the flip side of "use it or lose it."
Of course the article does responsibly point out that more than just the need of exercise should be considered before getting a dog. If pet ownership is too much responsibility, you can borrow a friend's dog or volunteer at a shelter. When needing a break from the pilates studio, I often walk to the dog park in Union Square for a little dog entertainment!
