Nintendogs Chihuahua SAV file editor?

Does anyone here know of a (free) Nintendogs Chihuahua rom save file editor, like AnimalMap for AC: WildWorld or like PokeSav? I reallly want one! :'(

Tried to do that once. No such thing exist. Mainly because it's not needed.

why not? You could create your own types of dogs or items or rooms! There's lots of stuff really.
OK, even if there is no SAV editor, is there any SAV trainer?

Definitely not for a game like this. Some exist for Pokemon because it's popular.
