Great tips, thanks! I tend to worry more about her little feet on the ice and snow than her body temps - hoping that she will have enough sense to come back inside with me if she feels cold! She only indulges in the longer 'snuffles' when it isn't as bitter
...and she doesn't seem to mind having cold feet - we keep up a pretty brisk pace though. I have examined her feet to be sure she isn't having any lasting effects. She seems to LOVE being outside, often bounding through snow up to her chest!!
