Herm Sprenger Chain Training Collar with Toggle

I'm very happy with this collar! I really like a slip collar or slip lead just because of how little pressure I have to use. But biothane and nylon only last about a year, and leather rubs his fur off. All the other chains that I've tried were too bulky and didn't tighten well, and my boy doesn't like things being slipped over his head. This collar tightens very smoothly and releases very quick, I believe that it will last a very long time. And I love the toggle, especially because I'm not so worried about breaking my finger
