We all know about actress Trisha's association with People for the Ethical Treatment of Animals (PETA). She has been chosen as PETA's Goodwill Ambassador for the 'Angel for Animals' campaign recently. And now, as a part of the campaign, the pretty lass shot for a new ad shot by G. Venkat Ram. The ad reads "Be an Angel: Adopt a Homeless Dog", encouraging people to adopt a homeless dog from an animal shelter or the streets. In this ad encouraging people to adopt a homeless dog, Trisha appears with a rescued street dog named Bambi.
