Porndogs: The Adventures of Sadie (2009)
Yellow Lab Sadie (voiced by Marilyn) is a pampered pooch whose life is turned upside down when she goes into heat and can't decide what to do with her newfound feelings and urges. When she learns that her owners are going to have her spayed, she runs away to the big city for a final fling.
This was Marilyn's final film.
