Usually I'm the one trying to think of things to entertain my fur-clients, but Coco had other ideas.
He was fussing at me every visit the last few days, to keep him company while he eats. Until recently, there were three dogs in this 'pack'. The other two are gone now, but Coco is still looking over his shoulder when he eats. It feels more normal to him if someone is there. (Charlie used to try to steal Coco's food, so Coco developed a habit of checking who was nearby.)
The last couple of visits, he started this silliness.
