Mischa Barton has revealed that she wants to appear on BBC Two's The Underdog Show.

The former O.C. actress became hooked on the six-week series, which saw celebrities including Julia Sawalha and Anton du Beke training dogs.

"I'm obsessed with it," she told WENN. "They give Battersea dogs to celebrities who train their dogs to do tricks. I would love to be on it."
