Do you need to keep your dog in shape to be in shape? We talk about dog fitness and how to keep them safe. No don't go run 15 miles if your dog has not run 1 with you. There are different things you can do to keep your dog limber, and fit so they don't get injured when you are out hiking, biking, jogging or chasing a ball. Just like us we need to stay fit but we don't have to run 15 miles to do so.
