A guide from Destructoid addresses whether players of the horror game Shift at Midnight can locate Guillermo, a brown Labrador who goes missing and is featured on a "missing dog" poster that appears on the game's notice board during night 10. Despite a $50 reward offered for his return, the article concludes there is no actual way to find or rescue the dog in-game, meaning the poster functions as a narrative device rather than an active quest.

The piece explains that, unlike Story Mode side quests requiring immediate action, the missing poster offers no dialogue options to investigate or search for Guillermo, and the game's Discord community has confirmed no one has succeeded in finding him. The writer suggests the poster exists mainly to build atmosphere and reinforce the player's motivation to protect their own in-game pet, rather than to signal a genuine puzzle, noting that even the poster itself lacks a functional phone number to call.
