First: Save your nintendogs + cats game and go to the home screen
Next: On the home screen click on the settings icon and go to date and time
Next: Click on time and set the time to 1 minute before midnight! (23:59)
Next: Go back to your nintendogs and quickly save then go back to the home screen
Last: When it is exactly midnight go back to your game and now all the contests will be open to enter!! :D
