Hey, for any of you out there who have older dogs and hardwood floors, I have two words for you-- yoga mats!! We live in an old house with all hardwood floors, just a few area rugs. We have an older Great Dane with amazingly slippery paw pads--once his feet start slipping on the wood floors, forget it. He loses all confidence and panics and won't move, or even worse, he's taken a few hard spills. I tried towels on the floor but they're still slippery if he steps on them at the wrong angle. Then it hit me, I had an old (never used ) yoga mat tucked away in our coat closet. Gives him a soft grippy surface he can walk on with no problems. It's amazing, like a magic trick for his confidence. Even with wet feet, he's surefooted as a goat!!
