DeGeneres adopted Charlie as an adult and has previously spoken about how he had the attitude of a dog.

“I have three dogs (Wolf, Augie and Kid) and three cats (Charlie, George and Chairman). I would tell you more about them, but like any celebrity parent, I think it’s important to keep them out of the press,” she joked. “Do I have a favorite? I couldn’t possibly answer that! It’s Charlie.”
