How do you get gold bar's in the game Nintendogs?

u leave on your Nintendo D.S. w/ the charger in for 2 hours(don't do any thing to it)then there will be a gold bar

Up above the line is the true ANSWER! from Doggy27

this works too, get a Chihuahua (white) and wear the lucky

collar and the cube clock. Once your walk bar is full, get every ? block and the last one will be the gold bar. Brett XD
