Talk to me

As a rambunctious five-year-old pit bull, he usually makes whatever he wants you to know fairly apparent. When Scooby first sees you, he tells you he's happy by wagging his tail and, when he's feeling particularly naughty, jumping up to lick your face. When he wants to play tug-of-war, he grabs a toy and presents it, his intent clear. When he's concerned, he barks, but only once or twice. Still, one can't help but wonder if there's more going on behind those goldenrod eyes than humans can understand. What unknown depths might Scoob be hiding, invisible to all but him thanks to the vagaries of vocal-cord evolution?
