This is all I needed to ease my old dog's fear of coming down the stairs. We have old wood stairs and one day he slipped, so he would NOT come down the stairs anymore, I ordered these, they came in 2 days, and Voilà, he started going up and down the stairs like a breeze. He is 13 - so apparently, you CAN teach an old dog new tricks! Thank you Wayfair for saving my dog!
