My dog has a bed similar to the others here - with the sort of wall around the sides and back. I think she likes having that wall. It is very important that the bed part be as thick and cushiony as possible, that bed with the golden lab looks great! As far as washability the more comfortable beds would be hard to wash. I would suggest getting a blanket, matching size and color, to place over the bed that could easily be washed.

Of course when it comes to nighttime my dog is in my bed - I can't wait til I get a place that's big enough for a king size bed!!!
