Millie loves the snow too, especially if her best buddy Hazel (the Staffie next door) is outside too! They will play in the woods for hours and hours, I just make sure to check on her and when she comes in sometimes I will give her a warm water bath (no soap). She LOVES it, I start filling the tub and she will actually jump in on her own. Then I snuggle her up in a towel and she sleeps on the couch for the rest of the day!
Interestingly enough, if it's cold but no snow I have to push her out the door in the morning to pee! Brrrrrr...!!
