Snape/Narcissa as spy

I just began rereading COS and the a thought came to me.  Dobby leaving  home to come and warn Harry.  Remember in OoP when Kreacher went to the Malfoy's it was after Sirius told him to "get out".  I was wondering if maybe Narcissa somehow gave Dobby indirect permission to leave the house as well.  I know he said he would have to put his ears in the oven door, or something like that to punish himself, but the whole thing made me think.  Maybe  I am reading too much into it having read all of the other book numerous times, over anylizing things.  It seems Dobby leaves his "masters" house alot.  
 
One more thing, not associated at all with the subject line,  in SS there is a mention of a "forgetfullness potion".  Wonder if Neville has ever been secretly given this in his pumpkin juice?
