Bring home a new puppy of your very own. Nintendogs: Dachshund & Friends lets you select from a wide range of breeds, from Dachshunds to Golden Retrievers, to find the perfect pet to raise, train and love. Touch-screen interactivity allows you to scratch and pet your puppy, while the built-in microphone lets you give your pup commands. If you train your puppy well enough, you can enter dog shows and agility contests to win new items and unlock new breeds. You'll have to take your dog for many walks, and with the DS wireless connection, you can stroll the neighborhood to visit with friends and their dogs, just like the real thing — with no mess to clean up.
Nintendogs is a step forward in the pet simulation genre, allowing you to directly interact with your puppy, not just press buttons. Selecting "scratch" from an options menu is one thing, but rubbing your finger on the touch screen to scratch your pup's tummy is much more entertaining. With more than 100 items to find, including flying discs and doggie outfits, Nintendogs will have you lapping up the fun.
