Re: Need traction... Paw-pad stickers? Boots? Wax?
If you decide to try the boots, I highly recommend the Grip Tex that MT Aussie posted. They are incredibly durable. Max wore one on his back foot that he was dragging. Our house is mostly carpeted, so he only wore it outside when we were walking. But they're easy to put on and take off and I don't remember one every coming off as we walked, even with him dragging it. The Vibram was super strong. Easy to rinse off in the sink and they dry pretty quickly.
