puppy paws and snow HELP

[Joseph Spada]

I am about to get a puppy in a week.  I live in New England.  We just
received a lot of snow.  I would prefer to housebreak directly outside ...
but am concerned about puppy feet and the snow.  also concerned how to
socialize the puppy if he can't go out in the snow/cold.  I have read a ton
of books and thought I was prepared - I will Barf diet, minimal vaccines,
clicker train ... I don't know if it's my cold feet or the pups but how do
people train in winter?
