It is the same in a single house. Put one dog in the correct-sized house with a tight door and you will see problems caused by excess humidity. Wood houses because of the properties of this material, usually breathe to a certain degree.

Every year, we have a client that has just moved into the area and builds the ultimate canine palace.
Winter arrives and on nights when the temperature drops below zero, the owner turns on the heat.

People often do not realize just how well their dog can cope with the elements. Shorthaired dogs have the same ability to keep warm as longhaired dogs. This is because their hair is different.
