Anyone notice what a dog will do if it chooses to lay down whilst outdoors?, the dog usually circles about in a treading motion, as if to lay down the vegetation, is it possible for such a species to think about comfort?, I know if I lay down for much more than a few moments on a hard surface I would be looking to relocate!...........when offered the choice of a sunlit portion of concrete drive, or a sunlit blanket on the same surface, both my remaining dogs choose the blanket, if I see the dogs lay down where no soft surfacing is available this is to the sound of bones clunking as "elbows" & hocks meet the deck.
