Over a decade after it launched on the DS, Nintendogs is still one of the most beloved games in Nintendo's handheld library. Its adorable virtual puppies, clever use of the DS's hardware, and widespread appeal resulted in a game that anybody could enjoy. The original Nintendogs was an immediate smash hit, becoming one of the best-selling games of all time, with Nintendogs + Cats (its 3DS sequel) later releasing to similar acclaim from critics and fans, alike.
