I love this leash! I have a 120 lb. rottie/shepard mix. Hes a big, strong boy and he likes to explore while on our walks, so the length is really great. I feel very secure using this heavy duty leash. I have just ordered a new one, as the one i have is about 2 years old and the spring inside which rolls the tape back up has kind of loosened up and the first foot or so of tape dosent retract anymore. But i cannot complain at all after using this for almost 2 years, almost daily. So its a great product, and i hear they are going to discontinue them. I hope not. This is the best leash ive ever owned!!!!
