my boy is 13.5yr old lab.  still going strong so I thought I would buy him the Cadillac of beds. 
he sleeps  anywhere but his caper bed. still choosing his old one. I found him getting up continuously from one bed to next.  last night I put him on the Casper and he slept stretched out like a king all night! I jumped on and found it so comfortable. Hoping he begins to sleep on it without my guidance.
