How to choose a good lead rope?

Choose a good lead rope, need to consider the following aspects:
Choose according to your dog's size and strength
Small dog: can choose light, soft nylon rope or rubber rope, the length of about 1-2 meters. This kind of lead feels comfortable, does not put too much burden on the dog and the owner, and is easy to control the movement of small dogs. For example, for Teddy, Chihuahua and other small dogs, a diameter of about 0.5 cm nylon lead rope is more suitable.
Medium dog: suitable for the use of high strength, good wear resistance of nylon rope or leather rope, the length can be appropriately long, such as 1.5-2 meters. Medium-sized dogs such as Labrador and golden retriever can choose a lead rope with a diameter of 0.8-1 cm, which can meet the needs of daily dog walking and ensure sufficient durability.
Large dogs: Given their greater strength, wire rope or sturdy leather rope should be preferred to ensure sufficient tensile strength to control the dog. The length is generally about 2 meters
