Can You Get Unlimited Money in Nintendogs?

No legitimate cheat code exists for infinite money in Nintendogs (DS). The game has no built-in cheat menu. Action Replay codes exist but risk save corruption.

Fastest Legitimate Money Methods

1. Disc Competitions (Agility Trial): Train daily. A 1st-place win pays $600–$1,000+. With a maxed-out dog, you can win 3x/day = ~$3,000/day.
2. Lure Coursing: Similar payouts; easier for some dogs.
3. Sell Found Items: Walk your dog frequently (30 min real-time cooldown). Pick up Fallen Meteorites ($3,800), Gold Bars ($2,000), Diamond Rings ($5,000). Sell immediately at Secondhand Shop.
4. Pedigree Prizes: Win 1st in Obedience/Agility at Championship level → rare items (e.g., Mario Hat, Luigi Cap) sell for high prices.
5. Time Skip (Not a Cheat): Advance DS system clock by 1 day → walk dog again → repeat. Warning: This locks time-based events (Bark Mode, shop rotation) for 24 real hours. Use sparingly.

Action Replay Codes (Use at Own Risk)

• Codes like 020Fxxxx 0098967F (Max Cash) exist for specific versions (US/EU/JP).
• Requires flashcart (R4, Ace3DS) or original cart + AR device.
• Can flag save as "hacked," preventing Bark Mode / wireless interaction.

Best Strategy

Focus on Agility training + daily walks. A well-trained dog earns $10k–$20k/hour of active play. You'll unlock everything (house upgrades, all breeds, interior items) in 2–3 weeks of casual play without risking your save file.
