If your dog lives in a dog house or spends a lot of time outdoors, you'll need to make sure your pet stays cool enough. During warm seasons, an enclosed structure, like a dog house, can heat up fast. One way to approach the problem is to install a simple air conditioning unit in the dog house.

Step 1 - Choose the Right Spot

Consider the placement of your dog house when deciding how to install the air conditioning unit. If the dog house is located close to an outdoor electrical outlet, you won't need to use an extension cord or install an electrical outlet under the dog house.

Step 2 - Choose an Air Conditioning Unit

You can purchase a special dog house unit or a small, portable air conditioning unit made for a window. For the sake of convenience, you might consider a unit with a timer or program function. Then you won't have to manually turn it on or off to maintain a comfortable temperature in the dog house all day long.

Step 3 - Make a Cutout and Build Supports

Take the measurements of your chosen portable air conditioning unit. Using a jigsaw, make a cutout of the same size in the dog house wall.

Then cut the 2x4-inch board to a lengh that is 2 inches longer than the width of the cutout. Attach this piece with screws underneath the cutout. Be sure to leave enough space between the support and the bottom of the cutout to accommodate a small shelf.

Attach two small triangle brackets to the support piece. Then choose a piece of scrap wood to use as the shelf. It need only be wide enough to lend additional support to the air conditioner. Use screws to attach the shelf to the triangle brackets.

Step 4 - Install the Air Conditioner

At this point, remove the air conditioning unit from the box and read the manual from cover to cover. Before installation, determine where the cord is on the unit. Drill a hole in the correct position in the dog house wall; make sure the hole is large enough for the cord to run out.

Follow the manufacturer's instructions for installation. Since you are not installing the air conditioner into a window, you need to wrap the unit in rubber weather stripping and seal around the unit with sealant. It is up to you how tightly sealed you need or want the unit to be.

For a finished look, add strips of molding around the window frame, inside and out.

Once you have secured the unit, plug it into a nearby electrical outlet or extension cord and turn it on. You may want to refer to the manual again if your air conditioning unit has a timer or program function. Be certain that the cord is secure and protected so it cannot be damaged or destroyed.
