hahaha - we have several beds at our house - we have a big rectangular bed without sides, like you see for big dogs -- this seems to be a favorite when the weather is hot -- a soft place to lay, but no sides to restrict air getting to them.
We have 2 oval beds with the removable cushions - one was really for the cats, but somehow became the dogs or they occasional share
then we have more of a donut bed
And I've seen a lot of pretty ones we would like to have -- but need to save up
