Building a house for someone whom you love so much, can be one of the toughest task for you to do but at the same time, most interesting too. And when it is your loveable dog that is going to reside in it, you will love to put your best efforts in it. Building a dog house is not as simple as erecting 4 walls and a roof. You need to make a plan of action before constructing a large dog house for outside or a small dog house for inside.
