my boyfriend got me the nintendo ds and the nintendogs chi version game for my birthday. it is really cute! ive gotten pretty far in it. i have 2 chis and a boxer...you have to compete in competions (agility, obedience, and disc competions) to win money to buy food and toys and to buy your dogs. they do have different colors but only a few. you can also win dogs by getting trainer points (each addition comes with certain dogs). the chihuahua version comes with chis, cavaliers, boxers, yorkies, german shepards, and shelties. But you can win other breeds (ive only seen a min pin so far). its cute once you get into it but the beginning is sort of slow. you can buy houses, go on walks, and give them baths. its good for rainy days thats for sure :wave:
