Our dogs spend their nights in the house, but how about yours? If your dog sleeps in a dog house, you need to ask yourself how warm and safe it will be as the weather grows colder and colder?

Our winters are cold but generally on the mild side. And our dogs spend most nights inside. So keeping them warm is usually not an issue. But if you live in a very cold part of the world, and your dog house is not super-insulated, you should be thinking about adding a dog house mat or heater to your doghouse - to make sure your dog stays healthy and comfortable no matter the weather.

Dog house heaters

Dog house heaters come in two types. The first is heater only and is for places like Minnesota where the summers normally do not get terribly hot. The second is a heater/cooler for those areas where the winters are very cold and the summers very hot - think North Dakota or parts of Montana.

Dog house heater only

One heater I found, The Hound Heater I, is 5.5" x 5.5" x 5.5") and is said to produce dry, reliable heat. When it's zero degrees Fahrenheit outside, the dog house will stay around 40-degrees F. This manufacturer also offers a small version called the Hound Heater II. It uses a light bulb to keep the unit's temperature at a constant 130 degrees when the outside temperature is below freezing. The manufacturer says, "The best part is, it is so safe and easy to install. It is made out of galvanized metal so it is super strong and will last for many years. The cost of Hound Heater I is $54.95 and Hound Heater II is $52.95.

Combination dog house heater/cooler

A combination heater/cooler is great for areas that are both cold in the winter and hot in the summer. There is apparently only one of these available - the portable PetCool unit. This unit looks very easy to install with 2500 BTU heating and cooling capacity. The manufacturer says that it "adjusts automatically to maintain a constant comfortable range of temperatures both as a dog house heater for winter and dog house air conditioner for summer, while also providing additional functionality as a de-humidifier lowering humidity levels 70%."

Be forewarned that the PetCool is not cheap with a price tag of $415.95.

Heated mats and throws

If your part of the country gets cold but doesn't get below zero for many days, then a good way to heat a dog house (and the dog) is with a heated mat or pad. The advantages of a heated pad are that it requires no maintenance, has no moving parts to get out of whack, is completely safe and can also be used in an unheated garage and basement. Most heated pads have an internal thermostat and some manufacturers offer an optional temperature control rheostat for heat adjustment.

Another alternative is to buy your dog its own heated throw or dog bed. A heated throw will cost about $73 for a large size.

The cost of a heated pad varies from $43.59 for the small size up to $66.99 for the large. A thermo throw will normally cost about $73 for the large size.

In other words, it won't cost you an arm and a leg to keep that best friend snug and comfortable all winter.
