Featuring the voices of Drew Barrymore and George Lopez. Rated G.

Imagine an entire movie based on the kind of dog Paris Hilton keeps stuffed in her purse. Are you done yet? Actually, Disney’s Beverly Hills Chihuahua isn’t quite as offensive as you might assume.

A live-action comedy relentlessly geared toward the preteen set, it aspires to be a salsa version of Lady and the Tramp. So what if the final product is more like a stretched-out commercial for Taco Bell? Consider that the bulk of the cast consists of computer-enhanced dogs voiced by celebrities who’ve seen better days. When you know that most of the on-screen talent can’t resist peeing on the nearest fire hydrant, it’s easy to keep your expectations charitably low.

Director Raja Gosnell gooses along a screenplay that’s part love story and part road movie. Our haughty heroine is a pampered chihuahua named Chloe (voiced by Drew Barrymore), who wears a diamond collar and revels in her 90210 zip code. She has no problem resisting the flowery romantic pleas of Papi, the lowly gardener’s dog (voiced by George Lopez, who has great fun babbling on like an overheated Ricardo Montalbán). Little does Chloe know that she’s about to get in touch with her Latino heritage the hard way.

It all starts when Chloe’s doting owner (Jamie Lee Curtis) is forced to leave her beloved pet in the care of Rachel (Piper Perabo), her less than enthusiastic niece. When Rachel takes Chloe along on road trip to Mexico, the chihuahua gets dognapped. After making her escape, Chloe meets a series of streetwise canines sporting accents straight out of Viva Zapata! (including a world-weary police dog voiced by Andy Garcia).

There are plenty of cheap laughs and more than a few cheesy stereotypes. But it’s all about as harmless as putting a bowler hat on an obliging bulldog.
