The make something called "Invisible boot" that you rub on a dog's feet and it protects them from the ice and salt. It can't protect from the cold of course. You are wise to keep Suzy inside if we have a really cold winter. I am lucky, none of my pets goes outside. They prefer their heat lights. I think even the doves like their space. It is big enough and always has food and water and feels very safe.
