How to Reset Nintendogs on Nintendo DS

No Built-In "Reset Game" Button — Workarounds

Option 1: Start New Save (Recommended)

1. Launch game → "Go Out" → "Dog Hotel" → "Donate Dog" for each dog.
2. Return to main menu → "New Game" (creates fresh save slot).
3. Old save remains but inactive.

Option 2: Delete Save Data (Permanent)

1. System Settings (DS/DSi/3DS) → Data Management → Nintendogs → Delete.
2. Erases all progress, dogs, items, money.

Option 3: Factory Reset Console (Nuclear)

DSi/3DS: System Settings → Format System Memory. Wipes everything—all games, saves, eShop licenses, NNID. Only if selling console.

Important Notes

• No "New Game" option exists while dogs exist—must donate all first.
• Donated dogs stay in Hotel; you can re-adopt later (same personality).
• 3DS Virtual Console version: same process via VC menu.

Start fresh guilt-free—your old pups are safe in the Hotel.
