Mickey Rourke wants you to "have the cojones to fix your dog."

The Golden Globe-winning actor for The Wrestler has put his renewed star power behind an ad campaign for PETA.

We all know how much Rourke loves his dogs after thanking them in his speech at Sunday's ceremony, saying, "Sometimes when a man is alone, that's all you've got is your dog. They meant the world to me."

Now, the actor is posing with his pup, Jaws, in a new spay-and-neuter campaign.

In a video posted on PETA's website, Rourke tells dogs that buying dogs from pet stores – and not having them spayed or neutered – can lead to overcrowding in shelters.

"When dogs get knocked up, puppies get put down because there aren't enough homes for them," the 56-year-old actor said.

"The most important thing about having a dog and loving a dog is keeping the dog its whole natural life," says Rourke. "You have a responsibility to communicate with your animal how much he means to you."
