I ordered the medium size for my 22-pound Cavalier spaniel. It is perfectly sized for her, and she spends a lot of time in it. I appreciate the fact that the whole thing is washable and not just the cover, as is the case with many other dog beds. The fabric seems to be high-quality, the color is attractive (blue), and at least on the first washing it held up beautifully. This dog bed is well worth the money.
