Paris Hilton at Project E's EDIN party held at the Parc Restaurant. Hollywood, California - 24.07.07

People For The Ethical Treatment of Animals and America's Humane Society joined forces to condemn Spears' pet shop purchase - and now Hilton has followed suit.

The socialite claimed the male Chihuahua from Pets of Bel Air on Wednesday (25Jul07), according to reports.

And it seems the animal activists are fighting a losing battle when it comes to persuading stars not to buy puppies from pet stores - Limp Bizkit star Fred Durst has also recently bought a Chihuahua from the same store as Britney and Paris, who have previously given homes to a Yorkshire terrier and a Chihuahua called Tinkerbell.
