By wearing it on your wrist it is perfect for when you are walking or jogging with your dog. SAFETY: Made of high-density climbing nylon providing nearly 2X the strength of similar rope! The reflective design allows you to see your dog in the dark, and with the 3M length gives your dog a very good range and freedom of movement while under your control. FOR S/M SIZE DOGS : This pet leash is suitable for dogs under 30 kg, small and medium dog types. Has an adjustable strap which fits every wrist.
