This Green Light-Up Harness is quick and easy to put on to your dog for daily walks. Simply have your dog "step in" to the left and right opening with its front paw and snap the harness shut around the back. Sturdy nylon construction and robust D-rings makes this one pet harness that will last. The straps are embedded with flourescent optical fiber that lights up for a neon light show. Set to three different modes (slow/fast blinking and solid) for a bright night walk with your pup.
