Super durable and backed by a lifetime warranty of adventures – never buy another leash again! Your dog doesn’t mess around when it comes to exploring, and neither should their gear. Made with ⅜”, durable rock climbing rope trusted by climbers - you’ll always have the strongest grip on even the biggest breeds! Designed with versatility in mind, you can tie knots for variation in length, use hands-free for trail running, or implement a harness-like configuration that's perfect for pups that pull. The carabiner locks securely to your dog's collar with a simple screw up mechanism, so you never run the risk of getting unclipped (or back clipped), and it makes it easy to safely clip your pup anywhere; whether organizing your trad rack at the crag or getting a cup of joe at your coffee shop.
