Using this Nylon Dog Leash is a breeze. Just attach the nickel bolt snap to your dog's collar, and you're ready to take your furry friend for a walk. When choosing a size, consider your dog's breed and strength. For smaller dogs, the 6'L x 5/8'W might be a great fit, while larger dogs may need the 6'L x 1'W. As for maintenance, simply wipe it down with a damp cloth if it gets dirty. Avoid exposing it to sharp objects to prevent tears. Store it in a dry place when not in use to keep it in good condition. And remember, always supervise your dog when using the leash to ensure their safety.
