I have a Golden Retriever who has arthritis. I got this ramp because he likes to sleep on the bed and I am afraid he's going to hurt himself getting up or down. This is a little slippery. His back leg slipped the first time he tried to go up. After that, he had a look like he was peering into the Grand Canyon when on it. He would put his front feet on, then he was like a solid wall any time I tried to get him to go any further. It's taken about a week and a lot of creativity (had to "fill in" the space between the wall and the ramp). He has not gone down the ramp yet. I know once he gets the hang of it, it will be ok.
