Clifford's Puppy Days is an animated children's television series that originally aired on PBS Kids from September 1, 2003[2] to February 25, 2006.

For his role as Norville, Winkler was nominated for 2 Daytime Emmy Awards for Outstanding Performer in an Animated Program for his work on the series, one of which he won in 2005.

He was adopted by Emily Elizabeth before he grew up into a giant red adult dog, forcing the Howard family to move out of their small apartment so Clifford would be able to live comfortably.

Like the original series, on UK airings, only one story is shown, with either the Storytime with Speckle or the Clifford's Idea to Grow On segments at the end, shortening the show to about 15 minutes.

[6] The opening theme, "Love Makes Little Things Grow", was composed by Jared Faber and Emily Kapnek (creator of Nickelodeon's As Told by Ginger) and performed by Freedom Bremner.
