"This is the headgear of choice when you really want to stand out in a crowd!"
— DS description, Nintendogs
The rainbow wig (Japanese: アフロヘア,afro hair) is a type of headgear in Nintendogs and Nintendogs + Cats. It can uncommonly be found on walks and in Nintendogs + Cats it can be obtained from Mr. Recycle if the player has enough materials. It sells for $16.
The afro is a fluffy ball of hair with vertical stripes of every hue of the rainbow (except for purple) appearing on the afro. In Nintendogs the colors seem to blend in with each other while in Nintendogs + Cats the colors are clearly separated and defined from one another.
