I totatlly agree with Whispersmom. ONLY use harnesses, PLEASE. And the retractable leashes are the best, because when you have a lot of room for them to roam, you can let it out, and then you can bring them in when you need to. Mine love it, I have used these since day one, and there was never any problem. They are lightweight, and they are never dragging on the ground, etc.
