How to Restart Nintendogs (Reset Save Data)

There is no traditional "New Game" option in Nintendogs, but you can completely reset your save data to start fresh.

Steps for Nintendo DS & 3DS Versions

1. From the main menu, select Options (sometimes labeled "Settings").
2. Choose Reset Save Data.
3. Confirm by selecting Yes when prompted.

⚠️ Critical Warnings

• Permanent Deletion: All progress—dogs, training, items, money, and competition records—will be lost forever.
• No Undo: This action cannot be reversed.
• Backup First (Optional): On 3DS, you can back up saves to a microSD card using Save Data Backup tools. On original DS, a DS Link Cable and computer are required—impractical for most.

Alternative: Adopt a New Dog

If you just want a fresh experience without losing your current pets, visit the in-game shop and adopt a new dog. You can keep your existing dogs while starting training with a new breed.
