Even though I work only about 35 hours a week, and we are looking for a house close enough to work so that my hubby and I can go home to visit when on lunch break. I wanted to get a doggie door put on the back door when I finally get a house this summer but Michgan has such extreme temperatures I don't think I can get a doggy door. Anyone with experience with doggy doors and extreme temps? Kind of out of subject, sorry. I have always wondered about that though.
