I used a action replay code and..

You used the cheat have all items don't use that cheat the cheat to get a lot of money and max trainer points are o.k. To use so if you want to delete your game press L,R,A,B,X,and Y.

Oh yeah,I forgot to tell you, press them at the spot that says Nintendo to delete your profile.

Ya umm if you used select to hack all items you can't buy anything even when action replay is out or when you code you deleted it happened to me too.

Woooow...i used the code 4evur ago & I just now realized that happened...=P

Well I'm new in this web but, I believe there is no way to get them back UNLESS reset your game. After you reset it click to have ALL items then after you get them save your game after that turn it on and max money and trainer points. Take you're dog for a walk and you get all dogs (WARNING:YOU WILL NOT GET THE DOGS U STARTED WITH) that's 1 way I figuered it out

Restart your game and don't use AR!

*SIGH* You have to be kidding me..... I did it too, and I've had this game for like 2 years with the same dogs, and I DONT WANNA RESTART T_T. *Sigh again XD* But I guess I have to......

Actually, there is a way to get it back! All you have to do is wait till your dog your dog is hungry, thirsty, and filthy. First, feed it natural dog food bag, then feed it milk, and wash it. By the time your done washing it (if you used infinite trainer points action replay code) you should get a ton of messages saying that a bunch of new dog breeds are now available in the Kennel. And there should be some new interior designs as well. But make sure you do all this with the dog in the top right corner. If it doesn't work let me know. If it does work, I'm glad I could help

Whenever you use the code "press SELECT to have all items" you can't buy any more dogs or houses. The action replay can get glitchy.....

Actually, I have another way to get more dogs in your kennel. If you have a friend who has the game too go on bark mode and choose a dog. You DO NOT have to bring a present, that is optional. Play with the other person's dog for at LEAST 5 minutes. You can do anything from feed the dog to throw it a ball or something. It only works for SOME dogs, not all of them. I now have a couple of dog breeds in my kennel, all from visiting someone else's dog. Please tell me if it worked!
