The veteran CNN journalist posted some sweet photos of himself with Molly on Instagram.
He also posted a snapshot of Molly, a Welsh Springer Spaniel, lounging on the sofa.
He first told the world about his dog in 2011 on his previous talk show, and also featured her in a 60 Minutes special on dogs and their emotional intelligence.
"I've always wondered if my dog is scamming me," he joked. “You look at your dog, and you're like, 'Do you really love, me or is this a trick?'" he said in the special.
He has not revealed how she died.
