First off, I have three dogs so I have bought many beds over the years. Oscar, my 13 year old 65 pound boxer has arthritis and is always wanting on my bed with the two little pups at night so I decided I needed to up the game for his own bed. I went for the large Casper bed and he LOVES it. It's rare that he even asks to get on my bed anymore. Our smaller pups love it too, to the point that Oscar will wake me up in the middle of the night to get them off his bed so he can sleep comfortably. I mean really, the bed is so big and comfy that sometimes even I fall asleep while cuddling with him on it. It is also very easy to wash and very durable. Seriously the best bed I have ever bought.
