Singer Sean Kingston joins the anti-chaining dog awareness drive by appearing in his first campaign for Loonies People For The Ethical Treatment of Animals (PETA).

The tattooed reggae star — who swept the charts with his Summer 2007 hit “Beautiful Girls” — is starring in a new ad campaign promoting PETA’s anti-chaining dog awareness drive, which discourages animal owners from leaving their pets tied up outdoors.

Sean — a proud owner of his own pooch, Sunshine — appears in the spot along with the canine and the tagline: “Chill with your dogs. Never chain them.”

“Look at it like being a human person. You’re family member is outside with no room to scoot, without a place to stay… that’s how they should look at it,” Sean says. “A lot of people should just think about: if that was them. I had dogs before, but my new dog Sunshine, I’ve formed a huge chemistry between me and her.”
