This Texas-made film languished in some film vault until Michael Herz and Lloyd Kaufman of Troma rescued it for direct release to video. The story has De Carlo, a wealthy woman, embittered by the fact that the only man she ever loved ditched her to marry her sister. Both of them are dead
now, so the vengeful De Carlo has to content herself with killing their children. She gives her niece a Rottweiler, then casts spells to make it attack. Sounds like a great bit for "Stupid Pet Tricks."
