When I got my first lakeland terrier puppy, I had an older lab cross as well.
Lakiepup used to gather up all sorts of objects and place them in Big Dog's bed, where he would lie on them in sort of "Mine, all mine" kind of way. These objects could include a dog toy or several, a shoe or two, a hairbrush, some dirty laundry (knickers and socks were favourites, retrieved from the laundry basket), a rubber wedge used to stop the bedroom door from banging in the wind and, best of all, the lavatory brush. He'd lie there like Smaug with his treasure.
If only mumsnet had been around then, he'd have known that lav brushes are the work of the devil and that taking one to bed with you was beyond the pale.
He also used to scoop tennis balls up using a small rubber ring, held in his mouth, and throw them round the living room in a game that obviously had rules of Byzantine complexity, known only to him.
He was the oddest (and naughtiest) little thing.
