Lishinu Retractable Hands Free Dog Leash THE LEASH, REINVENTED. A revolution in dog-walking, Lishinu provides more freedom and control for both you and your pup. Ordinary dog leashes are problematic for a number of reasons, the main one being the risk of escape in the event you let go for even a second. Lishinu straps on to the wrist and allows a natural free motion of your hands, so you can do more with your best friend. HANDS-FREE. A comfortable, adjustable neoprene strap goes on your arm quickly and easily. This changes what you can do and where you can go with your pet. Jogging, hiking, holding hands, tying shoes, opening doors, answering cell phones, carrying bags and anything else that uses your hands are all possible and safe with Lishinu. The Strap works as a hand-held leash as well for more control. Secure Lishinu to something solid for a moment if needed. ENGINEERED TO WORK FLUIDLY. An intelligent auto-lock mechanism makes it a seamless transition from retractable freedom to your dog at heel. It recognizes sudden movement and restricts the leash, giving you more control in more situations. It's calibrated to not lock too soon or dangerously, but just when you want it to. BUILT STRONG. Every part on the Lishinu is built to resist daily use and abuse. The neoprene strap, the 3 meter skydiving cord, the impact-resistant ABS plastic housing, and the laser-cut steel locking mechanism have been tested aggressively. Big dogs, small dogs, high energy and docile dogs, even chewers, tuggers, and barkers weren't able to best the human on the other side of the Lishinu, or damage any of its parts. SAFETY FIRST. Guaranteed to not harm your dog or you when used as directed. In the event of an emergency, simply pull the red safety tag, and it is detached in a split second.
