Those are great tips. I can't add anything to them since we don't have snow or very cold temps...........well maybe down into the 30's once or twice. I do take special care of their coat since winter tends to dry skin and hair out so bad. I give them hot oil treatments before the bath, then I add a tablespoon of Vegetable Glycerine to their conditioner. It keeps them from scratching due to dry skin.
