Ruffus the Dog is a Canadian children's television series which aired on YTV from 1998 to 1999; it was created by Robert Mills, who performs the title character, and developed with Cheryl Wagner.

The show was produced through Radical Sheep Productions, a company founded by Mills in 1985 that also created The Big Comfy Couch.

When Robert Mills left Radical Sheep in 2002, ownership and rights to the award-winning series were transferred to his new company, Hunky Dorey Entertainment.

The first major production was a re-telling of the Charles Dickens classic A Christmas Carol with Ruffus playing Ebenezer Scrooge.

Six of the show's original puppeteers, Robert Mills, Bob Stutt, Gord Robertson, Fred Stinson, Karen Valleau, and Ben Deutsch, returned for the project, as did songwriter JP Houston.
