What is a good temperature to keep the house during the days in the winter for Dori? This is our first winter in our new house and it gets so cold inside, compared to our old 3rd floor apartment. Right now I have the heat set to come on when it gets below 69. Is that too cold for Dori? It's a little cool for me, but I like wearing my pj's and socks and cuddling up with a blanket. She has plenty of warm places to lay but I wanted to make sure the overall temperature wasn't too cool for her.
