Sarah Silverman Duck Dog - P 2013

The comedian is inundated on social media with condolences, including one from former Twitter-quitter Alec Baldwin.

Sarah Silverman has bid a difficult goodbye to her closest confidante -- her tiny dog, Duck.

chihuahua-pug mix that lived to the ripe, old age of 19, Duck was first discovered by the comedian at a no-kill shelter in Van Nuys, Calif., where he had been brought after being caught by L.A. animal control running through the streets of South Central. He quickly became Silverman's self-described "best friend," and appeared alongside her on her Comedy Central series, The Sarah Silverman Program.

"He was a happy dog, though serene. And stoic. And he loved love," Silverman writes in "an obituary type thing" she posted on Wednesday to her website. In it she relays how a veterinarian came to the home after Duck had recently stopped eating and administered a series of shots that put the dog to sleep.

"I held him and kissed him and whispered to him well past his passing," writes Silverman, whose 14 years with Duck she calls her "longest relationship" and "only experience of maternal love."

The obituary was moving enough to coerce Alec Baldwin -- who has been almost non-existent on Twitter since his July flame war with a Daily Mail reporter -- to weigh in with his condolences.

"For @SarahKSilverman, who turned the dial on my day to the right frequency," Baldwin wrote, and linked to a photo of his own dog.
