In this chilling short horror film directed by Aidan Weaver, a seemingly ordinary day takes a sinister turn when a young woman, portrayed by Tiana Bes, brings home an adorable new puppy. What begins as a joyful adoption quickly descends into a waking nightmare as the pet reveals a deeply unnatural and menacing side. The woman finds herself trapped in her own home, facing a terror she never could have anticipated from man's best friend. As the tension escalates, she must confront the unsettling reality that this is no typical animal, and its intentions are far from playful. Featuring performances by Cathy Cavadini and Ginger Britt Daniels, "Good Boy" masterfully builds an atmosphere of creeping dread, transforming a familiar symbol of innocence into a source of pure horror. The film explores the vulnerability of isolation and the primal fear of a trusted companion becoming a monstrous threat.
