I now own TWO of these beds for my Doberman puppy. I got the 52" for him because I knew he would grow into it. He fits in it perfectly with room to spare! He loves his bed! When the new one came a few weeks ago, our puppy preferred to lay in that over our couch, which he is no stranger to. The bagel style bed is perfect because he loves to rest his head on it. The other bed that we've had since June has flattened out a bit, but our puppy still prefers it at night. I will say that cleaning this bed is not as convenient as others because you can't remove the cover entirely, but if you have an over-sized washer, or a cleaners near by that does, you can get it cleaned with no issues. My Dobe also can be rough when he plays, and when he chews his bed and plays with it, it holds up! My husband and I are very impressed. I will continue to buy these beds despite the cleaning inconvenience. I plan to get an oversized washer of my own in the near future. You and your dog won't be disappointed with this bed!
