LOS ANGELES – Like any true celebrity, Uggie, the Jack Russell terrier from “The Artist” and “Water for Elephants,” puts in his time on the treadmill.

At 10, Uggie doesn’t do a heavy workout, just a light trot and walking, said owner-trainer Omar Von Muller of Los Angeles. But Von Muller bought Uggie a DogPacer for those times when he can’t go out because of weather, work or paparazzi.

“It’s important to keep him in shape,” Von Muller said. “If they don’t get their exercise, they get old too fast, just like people.”
