I use my 15 and 30 foot leashes for doggy freedom in places they cannot legally be off leash, like in a park. That way they can still chase a ball, explore, smell, play, etc. while I still abide by the laws. None of my dogs ever actually need the leash. They are perfect when it comes to staying by me and coming when called, as well as walking in a heel off leash. It's strictly so I don't get a ticket!
