Did your kid get the game new or used? If it's used, the cartridge has the previous user's setup in it, and there may be more than one dog. A new game should only start out with one dog that you get from the kennel.
There is a way to clear the game to a fresh start if it's used- I think you press all the buttons at once- except the power button.
You can use the 'white record' function to record a voice message, and other people can listen to them in bark mode.
Now, look in the friends list. If there are no profiles there, you have not given out any info. When you interact with another DS, the profiles are automatically traded both ways. There is no permission asked or denied, apparently- it just happens.
I don't know anything about the camera issue, and pics.

BTW, my 11 year old son told me all this- I had no idea!
The game is new. And yes, there is one new profile of someone that owns a huskey.
I'm going to assume this huskey owner is an adult since there are no children within a two block radius of my house.
So this adult can talk to my son? Is there a block feature?
I'm not sure I like this at all :(
