Abstract
A leash apparatus includes a housing containing a spool assembly, a spring biased lever arm, and a first tensioning line. The first tensioning line is attached to a first end of the lever arm and wrapped at least once around the spool assembly, and has an opposite end attached to other than the rotatable portion of the spool assembly, such as a fixed location on the leash housing on a mounting of the spool assembly. A surface of the spool assembly slidingly rotates relative to the tensioning line portion that wraps at least once around the spool assembly. A second tensioning line is wound about the spool assembly and extends outside of the housing. The second tensioning line is guided around a wheel attached to a second end of the lever arm located on an opposite side of the lever arm.
