Dog Clothes

Do your Tzus wear clothes? You know, cute sweaters, shirts, etc..? Mine normally don't, but perhaps they should. I keep the Tzus cut pretty short, and when they go out in winter, I'm sure they're cold. But the thought of getting coats/sweaters on four dogs for them to go out to potty, seems like a boatload of work! Would they then be too warm to wear them inside? Mine don't seem to want to keep the sweaters on inside, so I guess they're warm enough in the house.

What do you do with your Tzus? Clothes or no clothes in the winter? I'd love to get some feedback on this.
