I have a smaller dog (14 lb) Mal-Shih-chin and she tore her CCL. I got 2 stairs to allow for steps in the living room during the day and stack them (one sitting on my hope chest at foot of bed). My dog is afraid of noises and dislikes all wood or plastic steps. I went with this brand cause it was heavier and just the right height for my particular usage. Steps are shorter than I imagined but that is perfect for her little legs (with back knee injured). Remember if your dog goes up the stairs commit twice the training to going down them. Your dog can decide to jump off whatever the stairs get them onto. My dog refuses to slow down despite needing to refrain from jumping on and off furniture. All and all this is exactly what I needed for my 11 yr old pup (she will always be a pup to me). As pictured and works great.
