Best Scientific Studies on Dogs
Dog owners are much fitter because they own a dog, which makes sense if you think about it. You have to walk your dog daily to keep him happy and fit, and so you too become fitter.
A study that included 2,000 adults discovered that those who regularly walked their dog were less likely to be obese, compared with those who didn’t have a dog to walk. Older walkers can benefit too, as in another study it was found that walkers aged between 71 and 82 could walk longer and indeed faster than non dog walkers.
