An outdoor dog will tolerate the cold much more than a dog accustomed to the comforts of a heated house. Usually the outdoor dog will grow a heavy fur coat containing a thick undercoat. This will insulate and protect him much more than the thin coat that is usually found on most house pets. In general, certain breed are also more adapted for the colder climates. Not only do these dogs have a thicker coat, some of them have a heavy layer of subcutaneous (under the skin) fat for insulation. Shepherds, huskies, Newfoundlands, and other heavy-coated dogs are better adapted for the cooler climates.

On a sunny day, as long as the temperature is not subzero, dogs can be left outdoors.A dry bed in a sunny, wind-protected area (southern exposure) should be available at all times. A thick layer of dry straw or a comfortable blanket makes good bedding material. If moisture is a problem, straw is the better choice. The bedding, along with the sun's rays, will keep your pet warm and protected. If your dog has a short coat or is not used to the cold weather, make sure that you let him in your house before sundown. The heat from the sun's rays are no longer available to keep him warm.
