SociaBulls: How Long can a Dog Walking Group Walk During the Winter?

We've always loved the quote "There is no such thing as bad weather, only bad clothes". Though E was just telling me of another quote "There is no such thing as bad weather, only soft people". 

Which reminded me of our Chicago SociaBulls group.

Last winter was the first winter for the group, and we weren't quite sure what we would do once winter struck. We planned for taking a hiatus, for certain times when it would just be too cold to walk.
Though we did have a mild winter, we only canceled one time for cold weather.
And this year we had no cold weather cancelations.

We do have smaller groups, but we have kept walking. Most of us don't have backyards, so we need to take our dogs out for walks anyway, which is more fun to do with a large group.
We do make accommodations bundling up our pups and ourselves: we don't stop for water breaks and we often create a shorter path if it's really cold. Plus, once you start walking, you stay a bit warmer.

How long do your pups usually stay out for walks?
