Double bill of canine adventures. In 'Beverly Hills Chihuahua' (2008), when pampered chihuahua Chloe (voiced by Drew Barrymore) gets lost while holidaying in Mexico, she is forced to rely on the kindness of various dogs she befriends as she tries to get home before she is captured by a villainous dognapper. Also in pursuit of Chloe is male chihuahua Papi (George Lopez), who is in love with her, and evil Doberman Diablo (Edward James Olmos), who has his eye on her valuable diamond collar. In 'Underdog' (2007), after an accident in the mysterious lab of mad scientist Dr. Simon Barsinister (Peter Dinklage), an ordinary beagle named Shoeshine (voice of Jason Lee) finds himself with extraordinary powers, and the ability to talk. Armed with a fetching superhero costume, Underdog vows to protect the beleaguered citizens of Capital City and, in particular, a beautiful spaniel named Polly Purebred (voice of Amy Adams). When a diabolical plot by Barsinister and his overgrown henchman Cad (Patrick Warburton) threatens to destroy Capital City, only Underdog can save the day.
