Those are nice photos of Keito! Hard to tell he is 'thin' in those shots. Maybe he lost some weight and is thinner than he was?

Funny about the rescue using him as a pillow. Aren't they sweet?

Well, I can't really say about the change in sleeping place. Seems like you've offered a LOT of beds. I'm surprised he curls up, you'd think an older dog would find that a bit much, and the dog would tend to sprawl more. Did you offer him a "donut" bed? Not that I'd say to go out and buy him yet another offering, he hee. Hugs to Keito!
