Shorty, Oscar Meyer, Razzle, Slinky and Conan. They're wiener dogs, dachshunds, charging down a greyhound track, their long low-to-the-ground bodies undulating, their floppy ears flapping, their pointy muzzles yapping, to the amusement of anyone willing to make the trip to La Marque. You don't normally hear laughter at a race track. Sobbing is more likely. But when Cinnamon, Rambo II, and Elmeaux lollygag out onto the track and look around in confusion, a body can't help but giggle. And when Nutmeg and Mortimer make a mad dash for the finish line a few yards away, but hook a sharp right instead to greet the cheering kiddies for a nice head-scratch, those giggles erupt into guffaws. For about $2 a head, you can't beat entertainment like this. Except maybe with the other annual kooky dog race, the Chihuahua World Cup, October 12.
