I think they look adorable in clothes, however, I try to not dress my girl when I can help it. I do put a sweater or several layers worth, and rain jacket and windbreaker and joggers and even use her jammie as an undershirt (being that it covers the legs like joggers do) when it's cold and/or wet out. Keeps off some of the chill, dirt and mud. Sometimes, in spite of dressing her in a fleece sweater/jogger, she's still not warm enough and ends up shivering.
I get so worried when that happens.
During warmer weather or moderately cool temperatures, I enjoy letting her coat and skin soak in some sunlight and I'm pretty sure she enjoys it also. And it's so nice watching the gentle breeze push her hair back slightly as she walks.
