According to the press release, Flash the Sheepdog was based on the "beloved" novel by Kathleen Fiddler. This film version was not held in so high an esteem. Earl Younger plays a Scottish orphan living with his uncle. The boy trains his Uncle's shaggy sheepdog, enabling the hirsute pooch to win several championships. The 58 minutes of Flash the Sheepdog goes by like...58 minutes. ~ Hal Erickson, Rovi
