Query: great leash!! (with one problem)

Love this leash. Great quality and really takes a good pull. Perfect if you have a medium or large dog. My only issue with this leash is the clip that connects to the collar. Nothing has happened with this one, but in the past, I've had issues with the spring mechanism getting loose and the dog being able to get off the leash. Instead, I use a carabiner or something similar, which you can pick up at any hardware store. Gives a little extra protection, in my opinion. Great leash though. The nicest I've had, with great colors you won't find a lot of places.
