Mine go on potty pads most of the time regardless of temperature.
I don't really have a temperature that I dont let them go out- once I need a sweater, I figure they need a sweater- once I need a winter coat, I assume they need a coat. If I can't stand to be outside more than a few seconds- then the same for them. They never, ever get put outside without me, no matter the temperature, anyway. So if its really cold, we just run in and out FAST!
