no action, but I still like it
You start of with $5,000( you'll have to pay an adoption fee), so when you start playing it you are going to have to choose a puppy at the kennel. There are six choices, but if you get the enough trainer points, you can unlock more. After you pick the dog you want you name him, not only by writing down its name but by saying it. So everytime you want to call your dog you say its name, whistle, or tap the call icon on the bottom screen.
So after you get your pup, you can start teaching it tricks. Pet it if you want it to learn (example tap the back and it will sit). A light bulb will appear at the top right side of the screen. There you can name the trick and say it on the mic. So if you want the dog to do the trick, you simply say it. COOL HUH. You can also clean your dog. buy shampoo, place it on him/her. Use the stylus to spread the shampoo around. Then use your stylus again to water it. Teaching it tricks and making it clean can get you a win at the Obedience Competitions.
You can also take your dog on a walk, everytime you take it out on a walk it goes further. So you can go further. While making the route you may notice question boxes. These can be items, or other dogs that are out on walks. On walk you can go to the park to practice playing the disc( For Disc Competitions), go to the gym( Agilty competition), and go to the secondary shop.
You can also, play with your friend's dog ( if they own a DS and a Nintendogs game)
If you love dogs, think using your DS mic is pretty cool, like to play with your friends(DS to DS), and would like to play something different for once. Get this game.
