Nintendogs obedience trial problems?

In nintendogs, my dog is having trouble responding to my commands. I have taught the dog sit, shake, lie down, spin, and roll over. I have fed him the light bulbs and the bones after he learns. I have gotten the message that he learned a new trick. He responds to my commands at home. However, in the obedience trial he doesn't respond to my commands. He just walks around aimlessly and looks at me. Very rarely will he do what I say. VERY RARELY.
Am I doing something wrong? Is there something I need to do that I haven't?
I've done all the things mentioned, and he still doesn't want to do tricks for me a lot of the time. has there been instances where people have had problems with the game regarding the audio input?

Make sure you're saying it very clearly for the mic to hear, and if you can't, just go to your options and change the sensitivity to "high." If you're just not remembering how you said the commands, you'd just need to erase all the trick and do them over.

@hiphop; I don't think that really makes a difference. I just don't believe the game was programmed that way...
