Former "Baywatch" actress Pamela Anderson has stripped for a racy new Valentine's Day-themed ad for animal rights organisation People for Ethical Treatment of Animals (PETA).

The ad aims to urge dog lovers to cuddle up with their pets during winter.

The actress-model, who famously starred in a sex tape with her ex-husband Tommy Lee, has a canine co-star in the artistic black and white video, titled La Chienne.

Anderson strips off in front of a cute pooch named Monsieur Brando and then climbs into bed with the pup, reports contactmusic.com.

Accompanying the film is a new message from PETA bosses, which reads: "With much of the country (America) in a deep freeze, Pamela Anderson has gone all burlesque to warm things up in a new Peta video. The message? Keep your dogs indoors and cuddle up with all your loved ones."
