I purchased the 36x27 inch comfy couch for my 17 pound cockapoo.  The size is larger than what is needed, but my dog is still enjoying using it. I put her blanket in it for her to get used to it. Now, she pulls the blanket out and lays in it. I was a little disappointed with the item that the back and sides aren't more pronounced like a couch since it's advertised as a couch, but since I was wanting it for a bed, it works for that purpose. I've already had to clean up a small vomit mess. I was very pleased how easy it was to clean the fabric. It cleaned easily and did not leave any stain or odor.
