I love this dog ramp it works great I have two older senior dogs they sleep with me in my bed . So I put this dog ramp on the side of my bed it works great . I had to train them to go up and down the ramp . But it works to help them get I to bed because they can't jump up on the bed anymore . I love how the bottom of the ramp that the dogs go up has sandpaper on it so the dogs don't slip going up the ramp .this ramp is the perfect size
