Inspired by climbing ropes, the Woolly Wolf Rope Leash is the perfect blend of durability, lightweight design, delicious colors, and sustainability. Just like every Woolly Wolf product, this leash is made of recycled PET bottles. The leash comes with a high-quality aluminum carabiner with twist-lock mechanism for added safety. A reflecting strip goes throughout the leash to keep your dog visible in the dark. With a built-in stretch, this leash provides a gentle catch when your dog decides to jump after something interesting. Available in two sizes: the classic leash with 10 mm diameter, and a thinner leash for smaller dogs with 8 mm diameter.
