A two or more subject retractable leash, and methods of use thereof, is disclosed, which includes a roll-back feature on each retractable leash. The leashes may be locked in place by engaging a single lever. The leashes retract regardless of whether the spools are locked or unlocked. Each leash retracts independently of the other leashes, such that a dual leash may be used to walk one subject. In some embodiments, a single subject retractable leash includes a roll-back feature that provides and allows for leash retraction, whether or not a brake associated with a spool thereof is engaged.
