I know what you mean about the snow sticking in their hair. Whenever it snows Louis goes hopping through it like a rabbit, and then he does this "face plant" in the snow over and over. I am not sure what he is doing, he just sticks his face in the snow like he is looking for something in there. Then when he comes in, he has snowballs all over his face and legs! I have some really funny pics of him!
(I also use a hairdryer to melt the snow.)
