Babe is an unusual part poodle.  Parti poodles have pure white hair with colored spots of color (any color).  Babe has one tiny spot of tan color on her face (visible in the first photo).  This will fade so Babe will be a pure white dog.  The other thing that is remarkable about Babe is that there is no evidence of tear stains.  These stains are controlled genetically so some dogs have the stains and others do not.
