Get out an extra mat because your favorite pet can now join yoga class! Doga has recently become a popular means of exercise because it allows you to do yoga with your dog. Depending on how large your dog is, you can incorporate it into your workout by using it as a weight or just using it as a prop to help you stretch better. Of course, the class — which includes massage and meditation for the dog — is also good for your pet. For more information about doga, check out this article from The New York Times.
