Do you prepare your pets for Winter?

Here in southern California it doesn't get too cold in the winter. Maybe the low to mid 50s on a really cold day. It still has been super hot here recently. The weather is going from over 90 degrees to 69 degrees and raining (just a few days ago). It's crazy really. But when it was cold last week, I put a little Halloween sweater on Gigi. Now, usually she hates wearing sweates, but she must have been cold because she actually was a little anxious to put this sweater on. It looked so cute on her, and she was upset when I took it off a couple days later when the weather jumped up 20 degrees. Silly doggie!
