Tired of running around the track? Need a work out buddy?
If you're a dog owner, why not give them attention and get a little work out?
Since I live in the dorms in college I'm unable to have my dog live with me. I do find time to go to the Humane Society with my friends and walk with the dogs. Some of the dogs are not leash broken yet and they literally drag you around the yard and down the road. Keeping up with them is a good way to get moving.
Maybe your dog will run with you but may not get this intense.
