High quality construction: Made from durable metal (iron). It does not stretch or break unexpectedly and is suitable for all dog collars. Tangle-free design: This metal double-ended lead features a heavy-duty 360-degree rotating swivel buckle for easy hooking, so you don't have to worry about your dog getting caught on the leash when walking two dogs, allowing your dogs to move freely around you. Multifunctional use: Whether driving or walking, it provides a certain degree of protection for your dog without disassembly or replacement. Chrome plating: The lead is all-metal with a chrome-plated exterior; it is not easy to rust or fade. To keep it in good condition, avoid prolonged exposure to moisture. Use scenarios: - Walking one or two dogs on sidewalks or in parks without tangling. - Driving or traveling with your dog to maintain control without changing gear. - Daily use with any dog collar, providing reliable protection without disassembly.
