Dog Size Modifier Codes for Nintendogs EU Action Replay

No reliable, publicly documented Action Replay codes exist to modify dog size in the European version of Nintendogs.

Why They Don't Exist

• Complex data structure: Dog size is tied to breed, growth stage, and multiple interlinked variables—not a single address.
• Anti-cheat measures: Nintendo's save encryption and checksums detect tampering.
• Regional scarcity: EU (PAL) codes are far less documented than US (NTSC-U) or Japanese (NTSC-J).

Alternatives

• Nintendogs + Cats (3DS): Officially includes breed size variation (small/medium/large breeds).
• Homebrew/modding: Tools like NTR CFW or save editors might allow size edits, but risk save corruption and are unsupported.

Warning: Cheating can corrupt your save file permanently. Back up your save (using Checkpoint or similar) before attempting any modification.

For other Action Replay codes (money, items, trainer points), search trusted forums like GameFAQs or GBAtemp—but verify the code matches your exact game ID (e.g., ASDP for EU Nintendogs: Dachshund & Friends).
