Amazingly, more copies of the game have now been sold in Europe, than in either Japan or the USA!

A staggering 4.5 million Nintendogs games have been sold since release last year - and unexpectedly, the majority of them have been in Europe. Despite surging sales in Japan and elsewhere across the globe, Europe has now sold two million copies of the titles - more than anywhere else, and only since its release over here on October 7th.

Nintendo say that "the innovative software has expanded the gaming population by attracting new audiences, including many female purchasers." Phenomenal sales have reached over 1.5 million in the US and 1 million - meaning over 4.5 million units of the little doggies have been sold worldwide.
