Bailey (born c. May 2018) is a pet dog belonging to United States Senator Elizabeth Warren of Massachusetts. A male golden retriever, Bailey played a role in Warren's 2020 presidential campaign and was a fixture on the campaign trail, appearing in selfies alongside his owners.

In the previous film, Bailey reunited with his longtime owner Ethan after being reincarnated as a new dog. Now a St. Bernard/Australian Shepherd, Bailey lives with Ethan, Ethan's wife Hannah, Gloria (the widow of Hannah's son Henry), and her 2-year-old daughter CJ on their farm in Michigan.
