Building a Dog House
 Master touch

This although optional will give your dog a very nicely finished house.
Carefully pain the dogs name on the front house, or if you are more artistic you can also add some decorative design and attach a small name plate.Like aforementioned, in colder climates we recommend you add insulation to the floor, there are several kinds, however the most practical in this case would be standard rigid foam insulation, which can be glued to the bottom without needing to add a second floor panel.
