I wish I had bought this sooner so that my 10 year old golden retriever could have gotten used to it before he got so cautious. We can still coax him up and down ( with kibble), but he will attempt to jump off the bed ( which he shouldn’t do) without guidance down the ramp. The ramp is sturdy ( he weighs 85 lbs), and folds easily for under bed storage. I wish it had more protection on the bottom against slippage and floor scratching, although we have not had either problem with it yet. I use a latex-backed bathroom rug under it to fix those issues. My only serious complaint is that I have pinched my fingers more than once when I close it. It is heavy enough to really hurt. Be careful if children are around it.
