AS soon as we brought this home Jonah has been loving it. He's just getting a bit older at 8, is on the bony side, and seems to be far more comfortable in this bed than in his old donut bed. We think it's the thickness of the bed. I HIGHLY recommend this bed for any dog size. The doggie day care place where we buy our food only has these for their dogs and say that all the dogs love them and compete to get on them. On a big bed you often see 3 or 4 perched up there. Anyway, this bed is a win!
