The first official trailer for Good Boy has arrived, and it takes a unique approach by putting viewers directly into the eyes of a dog. Released on Monday, August 18, the teaser introduces Indy, a loyal pup, and his owner Todd (Shane Jensen) as they move into a family home that has sat abandoned for years. While the house initially appears quiet, the preview wastes no time in showing that something sinister lurks within its walls.
The trailer opens with familiar lines celebrating the timeless bond between humans and dogs, including “man’s best friend” and “always by your side.” But the warm tone quickly unravels when unsettling noises break the silence. Eerie knocking echoes through the halls, and one chilling shot shows a figure slamming their head into a door. Indy, ever protective, is the first to sense danger, barking and investigating as the unease builds. The clip ends abruptly, leaving audiences unsettled and eager to know more.
Throughout the trailer, quick cuts show Indy racing through the woods, prowling the house at night, and reacting to unseen threats. A particularly tense moment comes when Todd’s grandfather, portrayed by horror veteran Larry Fessenden, lets out a “bloodcurdling growl” in Indy’s presence, hinting that the family’s history may be tied to something darker. The dog’s courage becomes the emotional core of the story, as the preview emphasizes his loyalty in the face of growing terror.
The official synopsis frames Indy as “our canine hero,” highlighting both his suspicion of the eerie house and his unwavering devotion to Todd. By framing the supernatural events through the perspective of a dog, the film heightens ordinary sounds and shadows into sources of dread, blurring the line between loyalty-driven bravery and genuine danger. The central question the trailer poses—“Can Indy protect his owner?”—remains unanswered, leaving audiences hooked.
Good Boy marks the feature debut of director Ben Leonberg, who cast his own dog Indy in the leading role. After premiering at the SXSW Film Festival earlier this year, the film is set for a theatrical release in North America on October 3, followed by a U.K. release on October 10. The cast also features Arielle Friedman, Anya Krawcheck, and Stuart Rudin, alongside Indy’s breakout performance as the courageous protector at the heart of the story.
