Does your dog prefer the cold or hot?

Well, we don't get any snow here in southern CA, but Gigi seems to prefer the colder months. She has really started to like wearing sweaters suddenly, which is good because the weather is finally starting to cool down over here. It gets really hot here in the summer; although, this summer came super late for us...like in early August. Then we started getting the over 100 degree weather. I can tell that even indoors and with the air conditioning on, Gigi is not as spunky.
