Finally the US Version of the game has been released:
Put a puppy inside your Nintendo DS! Described as a "puppy simulator", this innovative new title gives you a small amount of money to purchase your own puppy...and from there, the sky's the limit! Using the Nintendo DS's built-in microphone, you can name your dog, and then teach him tricks! Nintendogs also makes heavy use of the DS Touch Screen. Use the stylus to pet your dog, rub him on the belly, or touch his nose! But be careful: different dog breeds have different personalities, and not all like to be treated the same way.
