A visible dog is a safe dog. That's why our safety leash is universally designed to be bright day or night! The tough neon yellow nylon provides superlative daytime visibility, which makes it great for walks in the woods and hunting. When the sun begins to set, the reflective thread catches the light of headlights, streetlights, and other light sources, providing hundreds of feet of nighttime visibility. Every leash is 6 feet long, but we offer a 3/4 in. thickness for smaller breeds, and a full 1 in. thickness for medium to large breeds-because even big dogs could stand to be a little more visible! The sturdy clasp easily clips on and off your chosen collar or harness.
