Dug Days (also known as Up: Dug Days) is an American animated series of shorts created, written, and directed by Bob Peterson and produced by Pixar Animation Studios initially for Disney+. The series is set immediately after the 2009 film Up, following its main characters, dog Dug, voiced by Peterson, and his owner, 78-year-old Carl Fredricksen, voiced by Ed Asner in one of his last performances before his death.

The series was announced in December 2020, during Disney's Investor Day, with Peterson pitched the series centering on Dug following his work on Forky Asks a Question. The animators created new animation rigging, textures, and hair for the characters in order to update their original designs due to advances in CG animation ever since the original film's release. Due to the COVID-19 pandemic in the United States, most of the final results from the animating process were done from the crew's homes, and the cast remotely recorded their dialogue.

The first five episodes of Dug Days premiered on September 1, 2021, on Disney+. They received generally positive reviews for their voice performances, messages, role models, humor and emotional depth.

Carl's Date, the sixth and final episode, premiered exclusively in theaters as a short film with Pixar's Elemental on June 16, 2023.
