CONTROL Resonant Dog Guide — Mysterious Dog Locations & Every Dog Has Her Day
Quest title: This side story is logged as Notes: Every Dog Has Her Day — full zone table + Gap finale on that page.
Quick answer (CONTROL Resonant dog): The Mysterious Dog is a Side Story collectible chain called Notes: Every Dog Has Her Day. Find her once in each of 7 zones, return the missing Dragon Toy (teal/blue dinosaur plush) to her bed, then interact with her in The Gap. Completing the chain unlocks the Dog’s Best Friend trophy/achievement and the Untapped Trusted Spanner artifact (+15% Raw Damage). Unofficial companion — compiled from launch walkthroughs.
Finishing the quest unlocks the Untapped Trusted Spanner — craft notes on Artifacts. It also feeds Dog’s Best Friend on the Platinum path.
What is the Mysterious Dog side story?
Players searching control resonant dog are looking for the paranatural canine that shows up across warped Manhattan. She sits beside an empty dog bed, often on rooftops or gravity-shifted surfaces. Interact with her, retrieve the nearby plush, place it in the bed, then talk to her again. After the first meetup, the quest log tracks Notes: Every Dog Has Her Day.
Related names you’ll see in guides and trophy lists: Mysterious Dog, dog toy, Dragon Toy, dinosaur plush, Chowrap billboards (visual hints), Dog’s Best Friend, Trusted Spanner, and The Gap pet ending.
How to start the quest
- Explore until a white paw-print marker appears when you are near the dog (map / minimap).
- Interact with the Mysterious Dog beside her empty bed.
- Find the Dragon Toy close by (same look every zone: small teal/blue dino plush — some guides say purple accents).
- Carry the toy back and place / drop it in the bed.
- Interact with the dog again to clear that zone’s encounter.
You do not need to finish all seven in one sitting. Clear each zone as story / traversal abilities unlock (Shift, Reach, Elevate, Power Cores).
All 7 dog and toy locations
One Mysterious Dog and one Dragon Toy per major region. Order is flexible; Downtown is usually first.
| Zone | Dog location | Dragon Toy location | Notes |
|---|---|---|---|
| Downtown | Rooftop / garden along the road from the Oldest House (south / southwest edge in many guides) | Lower rooftop across the street by a stairwell door above a Chowrap dog-food billboard | Easiest starter; early traversal enough |
| Central | Rooftop north of East Park Station / east of Field Office area | End of the laser-filled alley north of the dog, under a lit Chowrap sign | Watch lasers on the return trip |
| Evacuation Zone | Red-lit inverted rooftop northeast of the Sinkhole / north of Main Street | Rooftop access door on the roof directly beneath the dog; Chowrap billboards nearby | Shift / gravity helps |
| West Incursion Zone | Shifted rooftop north/west of the Parking Garage | AC unit / ducting on a nearby shifted rooftop by a Chowrap billboard | Needs Shift from The Incursion Fault |
| The Park | High rooftop northeast, north of Mold Factory / Underhill’s Apartment area | Desk / workbench on higher rooftop east — use exterior elevator | Power elevator with a Power Core |
| Underpass | High structure northeast of the Research Site | Inverted ceiling / gravity floor directly above the dog | Follow red-carpet gravity route; Shift / Reach |
| Unknown | Garden terrace on Tower Island (NW of Field Office island) | Upper balcony / table near a downward BAR sign on the building opposite | Longest path; Reach + multiple gravity shifts; Pope’s Research progress for access |
Downtown — easiest first dog
Most players find the Downtown dog while exploring near the Oldest House road. Look for the paw marker on a rooftop garden. From the dog, scan the opposite rooftop for the plush sitting by a stairwell door above the Chowrap ad. Grab it with your traversal kit (Rush / Elevate / air movement), place it in the bed, and confirm the quest note appears.
Central, Evacuation Zone, and West Incursion
- Central: Toy is at street level in a laser alley — path is short but hazardous.
- Evacuation Zone: Dog on inverted red-lit roof; toy on the roof under her near the access door.
- West Incursion: Both dog and toy sit on gravity-shifted architecture west of the Parking Garage after you unlock Shift.
The Park, Underpass, and Unknown
- The Park: Elevator must be powered; toy sits on a higher roof workbench.
- Underpass: Toy is on the opposite gravity plane above the dog — drop/Shift carefully so the plush doesn’t fall into the void.
- Unknown: Tower Island garden dog; toy on a distant balcony (BAR sign). Longest carry — plan the gravity path before picking up the toy.
Finish in The Gap and unlock Dog’s Best Friend
After all seven zone deliveries, open The Gap (Dylan’s hub). The Mysterious Dog relocates there with her toys. Pet / interact with her to:
- Complete Notes: Every Dog Has Her Day
- Unlock Dog’s Best Friend (trophy / achievement — “Gain a furry friend” style description in trophy lists)
- Receive Untapped Trusted Spanner (craft at the Artifact Formation station)
PowerPyx and others count this Gap visit as an 8th “dog” interaction for 100% tracking — same dog, final step.
Reward: Trusted Spanner — is it worth finishing?
Yes for completionists and damage builds. Trusted Spanner is a damage-focused artifact: guides list +15% Raw Damage when equipped. KeenGamer-style crafting costs reported at launch: on the order of 4 Undefined Readings, 400 Source, 3 Violent Echoes (verify in your Gap station UI — costs can patch). After the quest, you can keep interacting with the dog in The Gap as a persistent companion beat.
Common questions about the Mysterious Dog
How many dog encounters are there?
Seven zone encounters plus the final Gap interaction — one Mysterious Dog repeating across zones, not seven different breeds.
Where do I find each Dragon Toy?
Always near the dog in the same zone — rooftop opposite, laser alley, inverted ceiling, powered elevator roof, or Unknown balcony. Chowrap billboards often telegraph the toy.
What do you get for completing the dog quest?
Dog’s Best Friend trophy/achievement and Trusted Spanner (+15% Raw Damage), plus the story beat of adopting her in The Gap.
Which abilities do I need?
Downtown can start early. Later zones (West Incursion, Evacuation inverted roofs, Underpass, Unknown) expect Shift and often Reach. The Park needs a Power Core for the lift.
Helpful tips while you hunt
- The Mysterious Dog, Dragon Toy hunt, and Every Dog Has Her Day are the same side story — one chain across all zones.
- Pick up the toy only when you know the return path — especially Underpass and Unknown.
- If the paw icon is missing, leave the area and re-approach; markers appear at proximity.
- Pair with other zone collectibles while you travel — e.g. The Last Taxi also spans seven regions.
