The first Peanuts TV special to not have Bill Melendez as producer or director.
One of Charlie Brown's flashbacks is an animated version of the first Peanuts comic strip from October 2, 1950.
The title is a reference to Charles Schulz's book, "Happiness is a Warm Puppy".
The first Peanuts TV special to be formatted in widescreen.
Filmed in a vignette style, every section of this video was taken directly from the original Peanuts daily comic strip, most notably from the 1960's. Rare animated appearances of early strip characters such as Patty, Violet, and Shermy are due to their use in those early strips.
