Chew Resistant and Wear-resistant: We had a chew test for 1 hour and the leash was not damaged. In fact, it depends on the degree of chewing and the temperament of the dog. For aggressive chewers (natural chewers), please choose carefully. Because some dogs chew all day long, and some dogs chew only once and leave. It is much better than other dog ropes in terms of chewability. After 100 friction tests, difficult to tear, super wear-resistant. Can be used in all weather conditions. Please rest assured to buy it. Float on Water and Difficult to Absorb Water: This dog leash can float on the water. So you will see if it entangles your dog's leg to save your dog in time. Dog leash is made of less absorbing material. It does not absorb much water, so the leash weight will not turn to heavy when you hold leash in water. It will not stick to sand, does not stink and is very easy to clean. Strong Strength Leash and Heavy Duty Hook: The leash is strong enough for dogs up to 200lbs with 1000lbs strength. Tangle-free to prevent knots from hanging. Uniquely designed heavy duty hooks are difficult to break, more durable, better than others. Reinforced quilting. ALL of this is to make sure that your dog does not escape with a broken leash.
