This is a wonderful quality heavy duty dog . leash. This leash is good and long . There is no way this leash is going to break it is so strong . It can be used on the strongest dogs . My nephew has a blueheeler and he is a really strong and big dog . He has broken so many different leashes ir chewed through them . He is not getting through this one . This leash is strong enough to keep him under control just fine . This is a strong very durable leash , I have had a wonderful experience with it . I received this leash at a deeply discounted price in exchange for my honest opinion.
