How to Restart Nintendogs (No Cheat Code Required)

There is no cheat code to reset Nintendogs. Use the in-game menu:

1. From the main menu, select Go Out → Save & Quit.
2. On the title screen, hold L + R + A + B + X + Y simultaneously (this triggers the "Delete Save Data" prompt in most versions).
3. Confirm deletion. This is permanent.

Alternative: If the game freezes, hold the console Power button to force shutdown (unsaved progress lost).

Always save before quitting to avoid losing progress unintentionally.
