How do you get money cheat codes on Nintendogs?
Well you can't get codes, but I kow a PERFECT cheat!
If you go on a walk and you get a piggy bank or a vase, drop it on your floor in your nintendog's house, but before you do that cheat how much money you've got. Then drop it, look at the money now, you've more money!
Hope this works!
PS: it might not work i have Golden retriever on 3DS
I am not sure about the codes but I know if you get a action replay you can get max trainer points which can let you get all dogs and lots of other cool stuff. The action replay also has lots of other cheat games like Animal Crossing and Pokemon and lots more. With nintendogs you can also get max money and lots of other stuff. Hope I helped! :} oops! :)
