We've only had this bed for a few days but my 40-lb mutt loves it. Our other dogs loved the coolaroo beds but our new dog (thin and nervous) wouldn't get on the raised bed at all. Finally purchased this bed and she loved it immediately. She stayed on it for 12 hours straight. It took two days before our other pup even got a chance to try it out. Now I'm ordering a larger one for him. I haven't washed it yet but I did order the fleece version b/c of the other reviews. Being able to wash the bed was a huge selling point. Overall, the dogs love it!
