KONG Explore gives large dogs up to 110 pounds a documented 24-foot, 3/5-inch-wide tape, plus a soft grip, brake-and-lock control, reflective stitching, and a 1.3-pound housing. It supplies the longest documented range in this first group and uses wide tape rather than a thin cord. That range also creates the greatest reaction-distance and entanglement burden, and its 4.1 rating includes repeated reports of button, retraction, and tape-wear failures, so it belongs only in open spaces where the handler can lock it short well before approaching traffic, people, bicycles, or brush.
