9 is pretty old for a biggie. Poor guy - I'll bet you are right that he's hot-natured and wants to cool off. But you'd think it would make him stiff to lie for a long time in a cold place. Is he kind of stiff when he gets up? My late Yorkies that lived to 9 and 13 never did show any evidence of stiffness even though they both must have had some form of arthritis at those older ages, one would think.
