We gave this to our 55 lb. Boxer for Christmas.  She loves this bed and stayed in it all Christmas morning.  Now when we dont know where she is, we find her in her bed.  Only drawback is non-removable cover.  
I was grateful to those that had commented prior to my purchase and agree that the bed runs bigger than what you would expect. I was very pleased I had ordered the large instead of the extra-large as it would have been way too big. .
