I would get him a winter waterproof jacket, Some dogs will wear boots, some won't(I never used them) but you would have to check his feet, when you come in and make sure he has no iceballs between his pads. Make sure you have a couple of towels, to dry him off when he comes in. There is a paw protectant-but he will not be out in the snow that much, so he shouldn't need that. Oh yes, and a hot toddy(for you!) Have fun! Someone who lives in the "high coountry" may have some other ideas! There are nice jackets that have the piece under the belly, too, so his underside won't get cold!
