You know it’s good for you. You know that exercise can give you energy, help you maintain a healthy weight, keep your muscles and joints flexible, help you live longer, and above all, make you feel better. For all the same reasons, your pets need to get up and get moving. Not only can exercise extend your furry friends’ lives; it may also expend some of their nervous energy and make them a little less likely to chew on the living room drapes.
