A Wii version was considered, but it was ultimately decided that the voice recognition, utilizing the DS's integrated microphone, was too integral to the experience. Because the Wii did not have a microphone, the player's dog would not be able to respond to their voice.

It was apparently decided that it would not merit the creation of an external peripheral, such as the Nintendo 64's Voice Recognition Unit required for Hey You, Pikachu!, despite the creation of the Wii Speak accessory alongside Animal Crossing: City Folk in 2008.
