Alicia Silverstone and controversial sports star Michael Vick have spoken out to condemn a video game which allows users to train and fight virtual dogs.

The animal-loving actress was horrified to learn about Dog Wars, a mobile phone application featuring fighting dogs, designed to run on Google's Android software. Now, the pregnant star has teamed up with People for the Ethical Treatment of Animals (PETA) to urge Google bosses to shut the game down.

In an open letter to Google CEO Larry Pope, she writes, "Dear Mr. Pope and officials of Kage Games, when I read about the new game Dog Wars, I couldn't believe my eyes. As a mom-to-be and someone who has adopted and loved rescued pit bulls, I join PETA's millions of members in imploring you to cancel this game immediately. If one dog dies as a result of this game, you will not forgive yourself."

Meanwhile, football star Vick, who served time for his role in a dog fighting ring, insists the game sends a bad message to impressionable youngsters.

A statement from the Philadelphia Eagles QB reads, "I've come to learn the hard way that dog fighting is a dead-end street. Now, I am on the right side of this issue, and I think it's important to send the smart message to kids, and not glorify this form of animal cruelty, even in an Android app."
