Lined dog harness size M. The harness is equipped with reflectors, so that your dog is more visible at night. Motorists will see your dog sooner, and you will find your dog faster when he walks loose in the forest. You can also attach reflective Velcro badges on the side for extra visibility in the dark. The harness is equipped with a stainless steel ring to attach the leash. This does not put pressure on your dog's neck or throat. At the top is a handle that you can use to lift your dog in an emergency or to steer him in the right direction.
