Product title: Rogz Utility Large 3/4" Fanbelt Reflective 13" Long Split Dog Leash, Black
Product description: Rogz Highly Reflective Utility Range is both the black tie and the 4x4 of the Rogz range. Timeless and classic, hardy but cool. Never shaken - or stirred. The 3/4" wide Fanbelt Split Lead with its woven reflective threads stitched into high quality webbing is a rock solid range for those dogs that have a taste for the better things in life and an appreciation of the classics. Straight-forward and durable with ultimate night time visibility. All joins are box stitched for extra strength and a quality finish. Note that this range needs to be turned inside out when operating in stealth mode as the reflective stitching is only found on one side. The 3/4" Fanbelt Split-Lead is suitable for Dalmation, Spaniel, Doberman, Boxer, Staffie and other similar sized breeds. Nickel-plated clip, rust-proof and tarnish-free.
Product feature: Split Lead to Enable Walking Two Dogs, Reflective Stitching, Box-Stitched Joins for Extra Strength, Nickel-Plated Zinc Trigger Hook to Prevent Rusting
