In the films, Dude is portrayed by a female dog named Paisley. Dude is voiced by Bobby Moynihan in Descendants 2 and Descendants 3, and Descendants: The Royal Wedding.
Dude first appeared during the scene where Ben was training Carlos with sprints. The dog was running behind Carlos until Carlos climbed up a tree since Carlos' mother, Cruella De Vil taught him to be cynophobic his whole life. When Ben handed Dude to Carlos, the two began to bond throughout the movie.
During the video chat with the evil parents. Cruella De Vil is surprised to see Carlos with him. She says he would make perfect earmuffs but Carlos stood up for himself and tells his mother that they love each other.
Dude gets the ability to talk due to eating the truth gummy Mal made for Carlos. He followed Carlos to the Isle of the Lost. He even gave Carlos great advice to finally talk to Jane. When on the Isle he was "proof" that the magic wand that Mal had created was assumed to the real one, he spoke when prompted causing Uma to believe she was getting the real thing.
Dude appears where he calls for Carlos about Jane's birthday but Carlos was helping his friends in stopping Audrey by getting Hades' blue ember. When Gil asks Carlos if Dude does have children, whether his children are able to talk, Dude laughs at it. After he laughs at it, he goes to Celia to get petted. He cheers when the two villain groups work together to defeat Audrey's enchanted knight armor. And later at the end, he is seen with Carlos at Mal and Ben's engagement party. While Jane is nervous about meeting Carlos's mother, Dude reminds her that she is Cruella De Vil and he is petrified.
