Champagne with that caviar?

We have snow!  And it's a beautiful thing.....except for one (ok, maybe more, but one I'll mention) side effect.  The rabbits that are still lurking in my yard are unseen, except for the poop that rests on top of the snow.  Tiny dark balls are scattered all over.  Gross enough.  But my dog seems to think these are delicacies.  I can not get her to stop eating them!!  This morning I was gagging as I watched her nibble them up on her morning outing.  She seems to think they're doggie caviar!  I need to make sure she doesn't lick my face anymore!
