Does your pet wear a coat when it is cold outside ?

We have been having an extra cold winter , at least for the South, it was cold. My two little dogs have been staying inside almost all of the time, and when they have to go outside for their chores; they really hurry and run right back inside.
I have dog jackets for both of them; but unless they are going to be outside for more than a few minutes, I have not usually been putting on the jackets. It takes more time putting the jackets on and taking them back off than to just let the dogs outside for their little run.
Before Christmas, we went for an afternoon out and walked around in the woods down by the Tennessee River, and it was a little chilly; but not really cold. Tootsie ran all over the place and didn't seem to be at all cold; but I put the little jacket on Chipper since he is older, and also he just walks along beside me and doesn't run all over like Tootsie.
Some areas have been having a very cold winter, so it seems like a lot of dogs would need to have extra warmth when they go outside.
