One of my dogs cannot be trusted inside while we're away, so add that to the fact that we have no garage or shed, and you can see why I had to come up with something.  In this instructable I'll show you how to heat a dog house with a 100 Watt flood light, a paint can, an extension cord, a lamp base, and a few other items you may already have.  The current set-up seems to keep an interior temp. of about 60 deg. F. in weather slightly below freezing.

Warning:  There is a slight risk of electrical fire if you do this wrong, so be careful and keep an eye on your completed, heated dog house for the first few hours it is in use.

Step 1: Here's What You'll Need

1.  A gallon sized paint can clean of all flammable substances or a tin can of equal or larger size.

2.  A 100 watt outdoor flood light.  Colored bulbs are recommended as they put off equal heat, but less light.  In colder climates a ceramic heat bulb might be a good idea, they put off more heat and no light, but proceed with caution as I haven't tested one with this equipment yet.  Here's some links so you know what I'm talking about.

  What I used:

  Ceramic heat lamp:

3.  One ceramic lamp base without a switch

4.  1-Gang Metal Ceiling Electrical Box, the kind that's roughly a 1/2 inch thick
Like this: 

5.  A wire clamp  to secure the wires to the box

6.  An outdoor heavy duty extension cord.

7.  A  drill

8.  Hole saw equal or slightly larger than the hole in the electrical box

9.  A set of drill bits.

10.  A jigsaw

11.  Small corner brackets.

12.  Screws and nuts the correct size to fit your electrical box and corner brackets.

13.  1/2 inch long wood screws

14.  Tarps or old dog food bags made of the same material (optional)

15.  insulation capable of withstanding the heat of the light fixture.  Radiant barrier car windshield sun screen will do. (optional)

<p>Its a great project and nice heater, but it is still a light bulb <br>!!! How would you like to sleep with 100 watts light bulb on whole <br>night ?? I don't think animals like the light being on all the time <br>either. I found an alternative <br></p><p><a href="http://www.thatpetplace.com/ceramic-heat-emitter-30-40gal-100w?sc=19&category=3293" rel="nofollow">http://www.thatpetplace.com/ceramic-heat-emitter-3...</a> </p><p>It <br> is a ceramic bulb, so it does not provide any light, but it heats the <br>space nice. Also adding a metal mesh is a good idea to avoid pets <br>touching the light/ceramic bulb, or just get a lid from the paint can and drill it with 1/2 inch or bigger drill to make holes.</p>
<p>Yeah, I listed a ceramic heat lamp as an option in the list of items required. The link no longer works though as it's been a couple of years since I posted this instructable. I've been using a ceramic lamp the last couple of years and it doesn't seem to get as warm, but at least I'm not worried about the brightness.</p>
I did this same design, but I used an infrared bulb, and believe me its nice and toasty inside. : )
Also, enlarge the hole and put the can halfway inside the house, then caulk with fire resistant 3m caulking its rated for over 1300 degrees. I tryed to make sure the sides of the can wasn't touching the plastic. <br> <br>Thanks.
I have the same dog house here. I put a piece of wood to block the lower half of the door and used an old rubber rug to make a flap for the rest of the door. Then filled the bottom with hay.
<p>better than light bulb</p>
<p>When we lived in Michigan, we had a wooden dog house, you can use heat tape, the kind used for pipes to keep them from freezing, and staple it around the sides of the dog house it'll heat your dog house, and will turn on and off, depending on the temps your is set to, ours turned on and off at 50*, we now live in Florida and it's not sold here, my dogs only go out during the day and any time the temps drop below 60* they die from the cold. LOL and we have a doggy door into our garage, and we have a dog house in there, but they're spoiled and get cold too easily and I don't want to worry about them while I'm not home, so I lined the walls of the dog house with Christmas lights and now they stay toasty in the winter.</p>
<p>That's a really good idea. I assume the tape doesn't get hot enough that laying against it could be harmful? I think I might try just doing it on the ceiling maybe on a foil insulation layer, so there isn't a chance of him laying against it.</p>
<p>we just used in on the ceiling and the floor, under the wood on the floor. I think the tape only heats to 50*, that shouldn't be hot enough to burn you or your dog</p>
<p>I wonder if there's a type of bulb that's a wavelength dog's can't see? That looks awfully bright to sleep in there.</p>
Our dogs generally get a good amount of straw and do fine. <br>Straw retains heat well and it allows them to make something of a den. I put a good amount in and open a hole at the door, and they end up with straw on all sides
Perfect timing! My cousin just posted a few pics of his dogs after he let them in out of the cold. I was telling him about putting a heat lamp in the dog house, when your post showed up on my newsfeed. Nice instructable. Should work for any type of doghouse, plastic or wood. Thanks!
Nice! I live in mid-west Ohio, where temperatures rarely get down below 0 in the winter. we have always put a regular light bulb in our dog house, the reason we haven't put a heat bulb in is because my dad claims my dog would never come out and she wouldn't develop her winter coat. Do you think this would be likely to happen?
hi, i did this same thing in dec. i use a 200 watt heat bulb &amp; it did get too for her. so i just used a floodlight &amp; she stays inside now. i also put a carpet door. i actually like your set up better. i just kinda hung the bare bulb inside after cutting small hole in roof. then i sealed with plastic bags, duct tape, tin, more duct tape, then spread that black stuff that u seal the cooler pans with. looks like tar? anyway, it worked. might re-do so it looks pretty like yours&gt; lol
