Stan, the titular dog of the series, was originally played by a Mutt named Kuma. Kuma was a Golden Retriever, Husky and Australian Shepard mix who appeared on the show for its first 5 episodes. Due to the show’s demanding filming schedule, Kuma was replaced by a younger dog named Mick for later episodes. Avery Jennings and Tyler James are step-siblings who are complete opposites. The household faces an even bigger adjustment when their new dog, Stan, can speak and also has a blog, unbeknownst to the loved ones.
