Nintendogs is the best selling Nintendo DS video game, though the sales include all versions of the game (five in all). In October of 2008 Nintendo announced that the game had set a new record of 20 million units sold. When the games were initially released, it boosted the sales of the DS handheld as well. The individual sales for each version are unknown, though the first week sales in Japan have been announced by Nintendo:
- Shibia & Friends - 75,000 units in week one.
- Miniature Dachshund & Friends - 49,000 units in week one.
- Chihuahua & Friends - 44,000 units in week one.
After the game became so successful, Nintendo released a bundle of the game that included a Nintendo DS and a version of the game that came exclusively with the bundle. While successful, exact numbers are not known.
