I bought two of these for my 70 pound weimaraners.  They are big dogs but they nap curled up tightly.  One took to the bed once I showed him how it worked  The other one does not like it - at all!  These are soft, plush beds and I thought the thick wall would help the dogs keep warm during the winter.  Even though I measured, the size is a little smaller than I expected.  The second dog doesn't have enough room to spread out and I find her lying in different contortions, looking very uncomfortable.  I'll have to buy her a flat bed so she is happy, too.

Pros: Good pricel, well padded, looks nice
Cons: Too small, the interior is smaller than I thought it would be
