One example embodiment includes a retractable leash for restraining an animal attached to the retractable leash. The retractable leash includes a housing, where the housing is configured to substantially cover the other parts of the retractable leash. The retractable leash also includes a spool in the housing and a leash. The leash is wound around the spool and at least a portion of the leash can be extracted from the housing. The retractable leash further includes an automatic brake, where the automatic brake is configured to lock the leash and prevent further extraction of the leash from the housing if the leash is extracted above a threshold speed. |
