The Nintendo DS is a video game handheld developed by Nintendo. It is the first console on which a Nintendogs game has been released. It is the predecessor to the Nintendo 3DS. Nintendogs was a launch title, also available in several bundles, for the original Nintendo DS. Nintendogs + Cats was a launch title for the breakthrough Nintendo 3DS. Nintendogs is compatible in all Nintendo DS and 3DS systems (Nintendo DS, Nintendo DS lite, Nintendo DSi, Nintendo DSi XL, Nintendo 3DS, Nintendo 3DS XL, Nintendo 2DS, Nintendo 2DS XL, and their 'new' variants), while Nintendogs + Cats is only compatible with the Nintendo 3DS lineup (Nintendo 3DS, Nintendo 3DS XL, Nintendo 2DS, Nintendo 2DS XL, and their 'new' variants). The Nintendo DS, along with its predecessor, the Nintendo DS Lite, are backward-compatible and are able to play games from the Game Boy Advance console.
