Does the questioner want to ask "Nintendo Dog's name is not recognized"? Waiting for system review. Nintendo Dogs is a social game. The reason why the name is not recognized is because the system is reviewing it, and it will be recognized after waiting patiently. You can first delete the previous game records of the puppy in the iQue DSi handheld game "Nintendo Dogs", and then you can directly call the puppy by the new name you want to change repeatedly until the light bulb flashes above the puppy game screen on the demo screen. When changing from small to large, a microphone pattern will appear. This is a reminder that the puppy game has started to memorize recording and you must clearly call the modified new name.
