Since they don't have fur, we put clothes on according to the temperature at her level. (We have a little thermometer.

) She spends most of day in my office that is NOT well insulated. So, on cold days we put a little shirt on her at home and something pretty if we go "out."
The first thing we did, once we new we were going to get her, is go to the store and buy her a pink coat!

It was cold outside and we wanted her to be warm on the way home. LOL
What can I say, it is our first little "foo foo" dog and we always wanted a little dog to dress up and take with us.
