The double dog leash is made of premium double-layered nylon fabric, making it durable and capable of holding up to 180 pounds. The buckle is constructed with steel for added strength and durability. Mountaineering rope and braided nylon elastic extension enhance durability while keeping the leash lightweight and easy to clean. The 360-degree swivel buckle design helps prevent tangling when walking two dogs. The leash length is adjustable, allowing your dog more freedom of movement. The bungee design helps absorb sudden impacts from energetic dogs, reducing pull sensation. The elastic cord extends from 20 to 35 inches, providing ample space for your dog to walk or run comfortably beside or ahead of you. If the product arrives damaged or defective, or if you experience any issues, please for assistance.
