She's been panting since 7am.  I'm definitely thinking we will have puppies today!  Yay!  She keeps trying to go outside and nest in the dirt.  Poor thing.  She really wants to have those babies in the dirt!  I read that they sometimes like to shred newspapers while in labor.  We will try to keep her in the whelping box while inside.  Of course she will always have a buddy by her side all day :)
