My Lab has a "toy box," that is in fact a large brass planter or such - he heads over and pulls out his bumpers (for fetch) or ball (for fetch) or chew toys or knotted rope (for fetch or tug-o-war). And this week he turned from the bin with one of his bumpers and the new blue heeler took it from him and turning, handed it to me. They are working suspiciously in-tandem to get what they want - to play fetch.
