Hello and welcome! I've seen pics of all the snow in Calgary right now and just wondered how all the bullies are doing!
As for the cold, one of my guys is in the same boat, he hates it! We coax him out with treats or a stick. Once he's outside, he's pretty much good to go and would quickly do his business and run back in. If there's a lot of snow, we'd shovel a path for them to roam around. It's really neat how they follow it and not venture outside the lines.
