If your pooch has a tendency to keep running long distances away from you while taking walks before you reel it in, this Power Generating Dog Leash will help you make use of all that wasted energy. All that coiling and recoiling of the leash will generate the power to light up the trio of LEDs that are available on this dog leash. To make it even more useful, it has a storage space that can hold doggy bags to gather up the poop that your pet will invariably deposit. Maybe it’ll be time to upgrade you dog leash when this hits the market later this year.
