Quick Answer
You reach the known horror house route by dragging the About Us dog into Petshop, then reopening the game. These are the currently known routes; this page will update as players discover more. Follow the skin, key, and candle steps below to finish the house route.
Which Pet Shop routes can you follow?
You can play normal customer service or trigger cursed mode, which leads into the horror house.
| Route or state | Conditions and outcome |
|---|---|
| Normal customer service | Follow customer requests using the bottom-row items; this doesn't prove a separate collectible Good Ending. |
| Cursed mode → horror house | Drag the About Us strange dog into the open Petshop window, reopen Petshop, and complete the modified orders. |
| House route completion | Return the skin, collect the key, visit the upstairs rooms, and finish the candle scene; this earns Hell. |
The last two rows describe stages of the same route, rather than separate endings you need to collect. Hell is the official achievement name associated with completing this route, rather than an official ending title.
Good Ending, Bad Ending, Secret Ending, and Stalker Ending are not official ending names. Those search labels don't prove additional Petshop branches or tell you how many endings exist. Use the Lacey's Flash Games endings overview to compare routes across the games.
How do you enter cursed mode?
You trigger cursed mode by dragging the strange dog from About Us into the running Petshop window.
Keep Petshop open
Open the normal Petshop and leave its window running. Move the window aside so you can still reach the website behind it. Normal service asks you to customize animals with the bottom-row items according to each customer's request. If you need help with that section, use the Pet Shop walkthrough.
Find and drag the dog
Open About Us on the website and scroll down until you find the strange dog. Drag that dog directly into the Petshop window. You can drop it anywhere inside; you do not need to wait for a particular customer.
Reopen the changed game
The Petshop window closes after the interaction, and the changed mode is saved. Open Petshop again to enter cursed mode. Complete the modified customer orders until the game moves into the horror house sequence.
Players report that dragging the About Us “bad dog” into Petshop helped when their game had crashed. That report describes the same dog interaction, rather than another ending condition.
How do you finish the horror house route?
You finish the route by restoring the cat, unlocking the upstairs door, and completing the rooms before the candle scene.
Return the skin to the cat
Outside the house, go left and take the skin from the bird. Give the skin back to the skeleton cat. This restores the cat and lets you enter the house.
Collect the key inside
Inside the house, go right toward the cage and interact with it. Wait until the dialogue finishes, then collect the key that appears. Take that key upstairs and drag it onto the locked door.
Visit the first room and bathroom
In the hallway, enter the first room and watch the entire bed/window scene. Visit the bathroom as well before trying the second room. You can interact with the bathroom mirror, but visiting the bathroom is enough to unlock the next room.
Finish the candle scene
Enter the second room, where you find the candle. Watch the full scene until it finishes to complete the route and earn Hell. The story deals with abuse and trauma.
What does a Pet Shop bad or secret ending search mean?
You can use those phrases to find the cursed route, but they are not official ending names.
The hidden dog interaction changes the game; it doesn't prove a separately named Secret Ending. Likewise, normal service alone doesn't prove a separate Good Ending you can collect. The full branch count and any additional ending conditions remain open details that will be added as players discover more.
For broader terminology, read the bad ending explanation or the secret ending explanation. Keep the dog trigger and house completion together when tracking this particular route.
