How do I delete my data I wanna start over again?

When you see the nintnedo sign on the top screen press and hold ABXYRL at the same time. It will say "Do you want to delete your save fale?" and then say "yes"

-SPADEds

Ditto. :(

I did work for me but it was tricky pressing all buttons at same time

ABYX L and R all at the same time (this should be listed in your Nintendogs instructions.) It can be tricky. I would just use your thumb to press all the square keys, and your index fingers for your side keys. If you can't do this, ask a parent or sibling for their help.

Hold b,x,y,a,l,and are and it will totally wipe out your ds hold it tight!

I was just about to add a 'this advice is total crap', but I gave it one more try, and it worked. You have to push them all down at the same time, and push them repeatedly in the few seconds after you start the game. It took me about 6 tries but I got, thank goodness. :-)

Turn on your ds and play nintendogs as normal and as the nintendogs sign comes up hold in a,b,x,y,L,are and it should say do you want to delete your data press yes if it doesnt work do it 3-4 times till it does work

It does not work what a rip-off why'd I buy thizz game?? >.>

Same reason you spelled this as 'thizz' :P

To delete all saved data on nintendogs when on nintendo sign hold L R buttons and use a thumb to hold abxy for 3 seconds and choose yes

Thanks,It worked. A bit tricky holding everything dowm together. I have one happy little girl now.

I restarted my nintendogs game but the button to buy supplies and to go out it gone !!! What can I do??

I've tried 10+ times and it's not working. My boyfriend tried also and still it didn't work.
