Rename Your Stardew Valley Pet

Upload your save, edit your pet's name, download the file. Cat, dog, or any 1.6+ pet species — even Shrine of Illusions can't do this in-game.

Drop your save file here

or click to browse — look for FarmerName_Id inside your Saves folder

Your save never leaves this browser.

Reading, editing, and downloading all happen on your device. Nothing is uploaded, sent to a server, or stored anywhere outside your browser.

How it works

  1. 1. Find your save in %AppData%\StardewValley\Saves (Windows) or ~/.config/StardewValley/Saves (Mac/Linux). Each farm has a folder named FarmerName_Id.
  2. 2. Drop the file with no extension inside that folder (the same name as the folder). Skip SaveGameInfo and any _old backups.
  3. 3. Edit each pet's name. 32 chars max per pet.
  4. 4. Download + replace. The edited file comes back with the same name. Drop it into the same folder, overwriting the original. (Back up first if you want to be safe.)

Frequently asked questions

Why can't I rename my pet in-game?
The pet's name is locked the moment you accept the pet. The Shrine of Illusions used to offer a pet-appearance swap, but 1.6 removed even that — and no version has ever exposed the pet's name. Editing the save is the only way to change it without rolling back to a backup.
Is this safe? Will the file still work in-game?
Yes. The tool rewrites the <name> and <displayName> tags inside the matching pet NPC block and writes everything else back unchanged, byte for byte. Stardew loads the file normally.
Does my save get uploaded anywhere?
No. The file is read, edited, and downloaded entirely in your browser. Nothing crosses the network. You can verify with browser DevTools → Network tab.
Does this work for the 1.6 pet species (turtle, etc.)?
Yes — the tool matches any NPC with xsi:type='Cat', 'Dog', or 'Pet' (the new generic species container added in 1.6). All vanilla pet species are covered.
Will the new name show in NPC dialogue and on the pet's bowl?
Yes. Stardew reads the name from the same tag everywhere — Marnie's mentions, festival appearances, the pet's interaction popup. The change is global.
Multiplayer — what if my farmhand also has a pet?
Both pets are listed. Edit either or both names; the download contains all your renames in one file.
What characters are allowed?
Letters, numbers, spaces, and most punctuation — Stardew accepts the full Unicode BMP. Names are capped at 32 characters here (the in-game UI shows ~12 cleanly; longer names work but may visually overflow). Newlines and other control characters are rejected.
