Spot a missing dog poster on the notice board during Night 10 of Shift At Midnight and your first instinct is to go find the dog. That's exactly what the game wants you to think. Guillermo is described as a brown Labrador wearing a yellow collar, and the poster promises a $50 reward for anyone who locates him. The problem? Every player who has gone searching has come back empty-handed.
What is the notice board in Shift At Midnight?
The notice board is one of the main ways the game delivers new information between tasks. The Store Manager also communicates through phone calls and written notes, but the board handles side content and environmental storytelling. When the Guillermo poster appears on Night 10, it looks and feels exactly like a side quest prompt, which is part of why so many players spend time hunting for him.

Can you actually find Guillermo?
No. After extensive searching by the community on the official Shift At Midnight Discord server, the consensus is clear: there is no in-game model of Guillermo to find. The surrounding forest is the obvious first place to check for a stray dog, but nothing turns up there. Viewing the missing poster also does not open any new dialogue options with customers that night, which rules out a social investigation route.
The poster lists a phone number for the owner, but there is no mechanic in the game that lets you call it. That detail alone is the clearest signal that Guillermo's disappearance is intentional set dressing rather than a solvable puzzle.

Why does Guillermo exist at all?
The poster almost certainly serves a lore function rather than a gameplay one. The most likely reading is that Guillermo belonged to The Dentist or another customer who has since been replaced by a doppelganger. If the owner no longer exists in any meaningful sense, the dog would have no one to return to, which makes the $50 reward a detail that can never be claimed.
This connects to the broader theme running through Shift At Midnight: the world around the store is quietly falling apart in ways you can observe but not fix. The missing dog poster reinforces that instinct to protect what you still have, particularly your own pet, without giving you any way to act on it.

Does the $50 reward matter?
The reward amount is $50, which would be meaningful if it were collectable. Bonuses from completing the Store Manager's requests do add up across nights, so a $50 payout would be worth chasing. But since there is no mechanism to claim it, the number exists purely to make the poster feel authentic. It's a detail designed to pull you in, not pay out.
For context on how money actually works across the game's systems, the Shift At Midnight pets guide breaks down exactly how much treatment costs and where your funds are better spent.
What should you actually do on Night 10?
Since Guillermo cannot be found, your time on Night 10 is better spent on the mechanics that do matter. Focus on the Store Manager's active requests, keep an eye on your pet's condition, and stay alert for doppelganger behavior among customers. The poster is worth reading for the lore context it provides, but treat it as background detail rather than a quest marker.

The Guillermo mystery is one of those touches that makes Shift At Midnight feel like a lived-in world rather than a series of disconnected tasks. The dog is gone, the owner may not exist anymore, and the $50 reward will never be collected. That's the point.
