How to get 100000 coins on nintendogs + cats?

Way #1.Enter Competitions.If your dog is bad at them,Save before you go and if your dog gets a bad score (2nd and 3rd is bad for me) then hit home close the software before you go home then you can enter contest all day untill you win!
Way #2.Part A.Walks,Go for the cones but don't go touchy touchy on them weave then elegantly.Part B.Presents and Secret Paths.When you find presents there are usually wood,stardust,metal bolts,Rubber tire parts ect. I know you can't sell them but you can trade them at Mr.R Shop.Hit "Exchange Parts"And click the Chopper (aka helicopter) And if you have enough parts trade it,it's sells for 80$.Part C.When you go on walks you will see sighns for downtown the beach and mountains,Somtimes you might see a girl walking a dog head for that sighn.It will Say "Do you want to head down the secret path?" Thats where you'll find a bunch of extra gifts around and there may be a piggy bank in one go to your house and save,throw the piggy bank as far as you can.The highest amout of money you can get is 100$.
Way #3.Well For this you need a Boy and a Girl dog same breed diferent colour, you need them alone in the house for a week take the boy on short walks the girl on no walks soon they will have a baby it will be smaller than the rest and you only can feed the baby formula not water or else it wont drink.And thats how you get a free dog and he or she can still compete in compitions You Just have to train he or she!Also ne more thing Keep your dogs in the pet hotel for 24 hours or so and your dogs will be as good as new!And those are a few ways to get money and A special shout out to my dogs and cats Bella,Mimi,Cheeka,Angel, And Cupcake The Breeds Will Be Below.

Well, the game was not programed with any given cheats. But once in a while you will find a piggy bank and only if you are really lucky you will find a promise ring those go for 1000 buckaroos. If you go for the petmeter and tied your 3ds to your scooter, you will end up with around 45-350 points- just when you scooter down your driveway! Biking only gives you 54 points, but can score high also. Good luck!
