Nintendogs: Dalmatian and Friends Hints

Buy a balloon and blow on the bottom screen to blow it up big. Then quickly tap and throw the ballon out to your dog, just like you throw the flying disk. Your dog will most likely bite the balloon and it will pop and your dog might start to cower (it won't be scared if your dogs description said your dog was brave). ENJOY!

PS: Try to buy lots of balloons because they're cheap and if they don't pop then you can put them away again
