It hasn't seemed really bitter cold here yet , maybe once or twice but that's about it. Chloe uses the potty pads but Sydney goes outside .
We still take them for walks daily or every other day. If it got bitter I may reconsider that

but for now we put their coats on and go for walks. We all kind of love the cold and snow ( which we have yet to get

) around here ...but I'm quite sure bitter temps would change that for me
