Morning Sickness?

Could it be?  I can't remember any of my girls getting sick during pregnancy but they can.  Pix just lost her "breakfast".  Yes I know it isn't morning anymore but they ate a late brunch today b/c my agility group had a trial and I went to work it and forgot to ask Henry to feed them. Pix ate well but about 30 min later up it comes.  She's not a barfy dog and she is acting great so what else could it be?  Hmmmmm....I'm going to think another sign in the affirmative!!!
