Actress and animal rights activist Kim Basinger is lending her voice to a hard-hitting new video exposing the horrors dogs are subjected to at a Georgia research centre for cosmetic dentistry.

The L.A. Confidential star signed on to narrate the short film for The Humane Society of the United States, whose campaigners captured undercover footage at a facility run by Georgia Regents University over the course of three months.

In the film, dogs allegedly purchased from dealers are used for exploratory operations, after which they are often killed.

In the harrowing video, which has been posted on, the actress says, "I'm Kim Basinger and I'm here to ask for your help on behalf of animals at Georgia Regents University...

"Dogs like Shy Guy, along with others, who may have been family pets, were all used for unnecessary dental experiments. Their teeth were pulled out and replaced. It's very painful, just look into their eyes. This is a glimpse of what happens behind closed doors at Gru. These dogs were killed for this little sample of their jaw bone.

"Each year in the United States, 65,000 dogs are used in labs. Let's start by protecting dogs like Shy Guy from the hands of unscrupulous dealers and unnecessary suffering."

Animal rights campaigners are hoping the expose will put pressure on Gru officials to stop buying innocent dogs from unlicensed dealers, known for animal welfare violations, and urge them to halt the painful pet experiments once and for all.
