I Doogled (Lokian word for using google for dog specific research) "Dog limps in snow" and came to the conclusion that it is not because his paws are sensitive to the cold (he is part husky afterall) it must be a sensitivity to road salt. He walks on the snowy parts of walkways rather than the pavement. This is to cool the sensation salt creates. The prescription for his Doberlimps? das Boots!!!!
