At times, I like to think of Duke, my beloved 11-year-old Shetland Sheepdog, as the canine equivalent of the actor George Clooney. Like Clooney, Duke wears his age with distinguished finesse. His once predominantly chestnut colored muzzle is now a brown/gray salt and pepper mix that broadcasts his elder statesman status. Yet even as an older dog, Duke retains a rascal's disposition -- his dancing eyes convey a whimsical mischief mingled with curmudgeonly weariness (and yes that is Duke's way of brilliantly channeling Clooney's performance in the Academy Award winning film The Descendants).
