Hi:

Looking for an elevated/raised dog bed.

I suspect a size small, possibly a medium. 

For a 14 year old, 20 pound dog who loves to stretch out. He has noticeable joint issues that supplements are no longer having much effect on.

Or....I would very much appreciate a "regular" cushioned dog bed.

A raised bed would be incredible, but probably not likely, so a "regular" cushioned bed would be definitely be the next best thing. And absolutely appreciated, by both of us. 

Thank you so very much for considering it. 

:)
