Abstract: An improved pet leash (10) includes a single pulley system (12) having a pulley handle (12B) located on either distal end, the pulley system (12) being pivotally connected to an elastic cord (14) that is secured to a conventional lease (16). The pulley system (12) and the cord (14) cooperate to reduce or eliminate the pulling and jarring effects of a pet when engaged to a lease (16). Specifically, the improved pet leash (10) enables the user to run, jog or walk with a pet more effectively and efficiently by eliminating or reducing the ability of the pet to disrupt the exercise routine. The pulley system (12) is designed to allow the user a full range of arm motion while the elastic cord (14) absorbs the pulling and tugging effects of the pet. Pulley handle pads (12BA) on each pulley handle (12B) enable the user to maintain a firm grip of the pet while running or walking.
