ours all 'shout' at each other when they are playing. :rolleyes:
they especially like shouting at those who aren't playing or have a particular toy that they think should now be theirs!
they knock lumps out of each other with the shoulder barging and boxing, and they love to chase each other round the kennel. they are really funny to watch especially when the top dog gets up and decides to give them all a telling off for getting too noisy and boisterous.
