Actress and animal advocate Katherine Heigl is hosting the PBS premiere of “Shelter Me,” a film sponsored by Halo, Purely for Pets that illustrates how people’s lives are positively impacted by shelter dogs.

The one-hour television special, created by filmmaker Steven Latham, celebrates the human-animal bond by showcasing three inspirational stories about shelter dogs and the lives they change.

“As a huge animal lover, I was immediately drawn to this project because it advocates for the homeless pets at our local shelters,” said Heigl. “It’s important to generate awareness and overcome stigmas about these local facilities as well as promote these amazing animals and how they improve people’s lives.”
