I have built (mostly) a duplex for my two dogs. It's seperated so they each have a room. There is an air gap in the partition wall for air flow. The doors are just loose strips of rubber molding. The walls are insulated and the roof is too. If I'm home, the dogs are in most of the time. Betty is a 45# 6 year old dog and Barney is a 85# puppy.
How can I add some heat in there for when I'm not home?
