This compact, all-in-one leash is exactly what every busy dog owner needs. The 6″ leash folds up inside the small case which also not only conveniently holds pick-up bags, but can also attach to your belt loop so you can walk your dog hands-free. As an added bonus, the end of the leash also forms a collar, so you have literally everything you need to take your dog with you, all in a case the size of a sunglasses case.
