The puppy behaves beautifully, and stands securely on the non-slip surface, all business as soon as the noose goes around his neck. I love the rotation; it's easy to wedge a rubber ball beneath to stop it turning when stability is wanted (in future, a brake would be a good addition).   It was simple to assemble, and will stash in a closet or under a bed. Very sturdy construction; I expect it will last for years. I'm really happy (and so is Kiltti, as you can see in the photo).
