Joan Rivers is starring in a new campaign for PETA, People for the Ethical Treatment of Animals, ahead of what would have been the comedian's 84th birthday.

Although Rivers, who previously hosted E!'s Fashion Police, passed away tragically in September 2014 at the age of 81 after what was supposed to be a minor throat surgery, her legacy lives on in her many projects, including several books and a new PETA campaign.

On June 5, PETA released Rivers' new campaign, which uses one of her trademark jokes to encourage people to adopt animals.

"A study says owning a dog makes you 10 years younger," she said in the campaign, via E! News. "My first thought was to rescue 2 more, but I don't want to go through menopause again."

The photo used in the campaign was shared with the agency by River's daughter, Melissa, and shows the comedian tangled up with a dog on a leash.

"I love rescues and runts," Rivers told People magazine in 2010. "It's always the one that gets pushed aside that needs the love and will love you back that much more."

Throughout the past several years, Rivers has taken part in numerous campaigns for PETA and even helped the organization lobby the New York City Council to pass bills which ultimately resutled in an increase in licensing fees for unneutered animals and prohibited dogs from being chained outside.

She also hosted PETA's Passover hotline to promote vegan ham and helped the organization promote her daughter's anti-fur billboard in NYC's Times Square.
