Unidentified Dog

A small, unnamed domestic dog whose distant barking punctuates the reconstructed Aster home. The canine's vocalizations arrive only as off‑screen sound through an open window, anchoring the alien‑crafted environment in tactile domestic reality and reinforcing Jeremy Aster's sense of Earthly familiarity. The dog never appears physically or interacts with characters; its presence functions purely as atmospheric audio, heightening the scene's comfort and making the illusion feel convincingly lived‑in for both Jeremy and the audience.
