We were surprised the training leash is so thin. It feels "wimpy", actually, and we wondered if it might break if one of our dogs decides to suddenly try to chase a rabbit. The handle feels especially thin and inadequate. We live out in the country and this could happen during any morning walk. Fortunately, we had purchased other longer leashes from you several months ago and we were able to unhook the handles from those leashes and attach them to the new shorter leash. We tried them this morning and the leashes feel more secure in our hands with the thicker handles. Now the original handles look like a colorful decoration. We have a 55 lb. Basset Hound and a 48 lb. Border Collie mix and the training leashes with their original handles don't feel strong enough to "hold" them.
