The Scooby-Doo Dynomutt Hour

The Scooby-Doo Dynomutt Hour is a 60-minute package show produced by Hanna-Barbera Productions in 1976 for ABC Saturday mornings. It marked the first new installments of the cowardly canine since 1973, and contained the following segments:

Production

The Scooby-Doo Dynomutt Hour debuted 11 September 1976. After two months, an additional 30 minutes were added to this hourlong series (to accommodate repeats of the first two CBS seasons of Scooby Doo Where Are You!), becoming the 90-minute Scooby-Doo Dynomutt Show, which it remained from 4 December 1976 through 3 September 1977.

Like many animated series created by Hanna-Barbera in the 1970s, the show contained an inferior laugh track created by the studio.
