Devil Dog: The Hound of Hell  (1978)

Theatrical Release Information:
Devil Dog: The Hound of Hell

Though not actually a film addressing the evil lure of cream-filled chocolate cakes, this amusingly cheesy made-for-TV opus from director Curtis Harrington pits a relatively normal suburban family against a slavering, demonically-possessed German shepherd whose hunger for human souls far exceeds that of the normal household pet. Although not above resorting to the usual throat-maulings, the satanic psycho-pup's preferred method of attack is to supernaturally cause the deaths of various friends and neighbors, in a style reminiscent of The Omen. Though the gory potential of this scenario is obviously dulled by the TV-movie format, there are enough implied shocks and chills to keep up the pace -- particularly a grueling scene in which Dad finds himself unable to resist the urge to plunge his hand into a spinning lawnmower blade, while the possessed pooch looks on with tongue-wagging glee. ~ Cavett Binion, All Movie Guide
