There is often an issue with heat in my home. I don't like it. Willow does. So, we have agreed to disagree. When the heat does come on (rare) she rushes over to the heat register, which is located under the curtains, and dances in front of it and snaps her dog jaws at it to capture as much of it as she can. I usually watch and laugh. This day, when it shut off, she swung around, sat down, and stared at me. With the curtain on her head. For five whole minutes. I got the message. I turned the heat up.
