Enter the activities menu and choose "contests" (spanish version of the game, i don't know their exact english names)
Even you fail, you get some money, and practice!

@lunarjade: Congrats on your new kitty! mine is still hissing around, but it's much less than before!
btw, i doubt accessories have any effect in your pets.

@abgar:-
Thanks abgar. I'll look for that first thing tomorrow. I had felt it was sensible to start something - even for the practice.
I'm really grateful for everybody's hints and tips. Off to bed now.

Hey, I just got nintendogs+cats and I am trying to get money but when I do it takes forever to get alot. I got a golden retriever that I named Ace. Its taking forever to get alot of money in contests.

Well, you will start getting lots of money eventually.

You simply need to train your dog.

Cool! Thank you for the Information.

w00t just got the Mario room. My life is basically complete.

Also, thinking of getting a second cat. But what to name him/her? I have Olimar and Louie... what was the name of the business owner in Pikmin 2? The guy Olimar worked for.

His name is simply "The President," though his name in Japanese is "Shasho," which is the Japanese word for "president." I hope this helps!

"President" sounds like a good name for a dog.

Ahhh I couldn't bring myself to name my new kitten that, so i went with Hocotate instead. Keepin' the theme alive!

Well, we tried disc training in the park - and ended up practicing more with the other pups there than Dido, who seems happy to let the others butt in on her games. Dido was described as very calm natured at the kennels - I guess she's just a bit too laid back at the moment. So we practised at home and then came third in the junior disc championships - we were both a disaster :/
Still, we did win £10 (and sold a spiked collar we found in the street), so we won't starve yet a while, though a kitten is off the cards at the moment. We also had a much more successful training session in the park this afternoon. Slooowleey is my motto at the moment

I just saw wobee's post, and decided to see if I had unlocked the Mario room yet. Turns out I did and I bought it right away! It's awesome, I can faintly hear Mario coin sounds coming from somewhere...

Olimar saying hi to Hocotate in my sweeeeeet Mario house.

I swear, every game should allow for pictures to be taken. This and Pilotwings has made me trigger happy for photos.

Ohhh, wobee, you got the koopa chair! I saw it in the store, but I didn't have enough money for it. I think I might have enough money now, though. O_O
/me runs to furniture store....or was it the store that's open only after it rains...?

EDIT: I went to the furniture store and the koopa chair wasn't there, but a table set in Mushroom style was, so I bought that.

My one laid back pup!

@Tj92:-
Would you have time to post a pic of the Mario room - with puppy, natch? Also, have you discovered yet what happens when you've won top dog in the three categories? Do you just carry on entering to improve your scores, and get more money, or do you start off again with your second puppy? Just interested
@wobee:-
Just saw your Mario room as I posted this. It's really cute. I gotta get on the competition game!

I don't know what you mean by "natch"...
I'm trying to win the Lure competition right now, but it's hard, and next up is the obedience competitions, which I'm not even very far in right now, so I don't know what happens if you win all three. And even though Midnight is my main bread winner, I take my other puppoes to practice for competitions whenever I have the chance, and they all participate in their own little competitions.

Me wants a mario room.
And yes, i wish every game for the 3DS had the ability to take photos, it should have been a 3DS home menu feature.
@mowzle: when you win first place on a competition, you unlock the next level, in that level you win more money. You can enter any contest twice a day, im not sure if it's twice for dog or just twice a day.

I can't seem to get this public computer to detect my SD card, do I can't post a picture of my Mario room right now...

@Tj92:-
Sorry - perhaps "natch" is a bit "British" - it means, naturally I would want to see your pet at the same time as seeing your room.
And I'm sorry you're having to fight with a public computer, that's really a pain.

Thanks again to everyone for enlightening me, I feel a bit dumb really

A video Josh at BitBlock made a while ago of buying the Mario room. Don't worry, it doesn't cost 400,000 in our versions, his is just japanese and thus uses yen.

Also I just bought the Toadstool set as well. I'm finally happy with my Nintendogs house, seeing as this looks most like my own room haha.

I think Mowzle may have been asking what happens when you win Nintendog cup champion in
every contest with a single dog.
