Size of Sleeping Area Floor Space - With each inch of your dog's height (measured from top of shoulder to ground) allow 36 square inches of floor space. For example, a dog 12 inches tall needs 432 square inches of floor space, or a floor area of 16" by 27" = 432 square inches.
Height of Sleeping Area - Add 1 or 2 inches to your dog's measurement when in a sitting position (from top of head to ground), in order to determine the ceiling height. For example, a dog 12 inches tall will have a sitting height of about 14 inches and the doghouse ceiling should be 15 or 16 inches high.
Overall Doghouse Dimensions - For example, a Dalmatian (20" tall, sitting height 23") doghouse should measure: sleeping area - 20"x36"; hall area - 12"x20"; ceiling height - 25"; doorways - 10" square; roof - 36"x72".

- A cold weather house made from a frame of 2"x2"s, with a 1/2" or 3/4" weatherproof plywood exterior. For better protection from the cold and wind, it has an entrance and hallway that are separated from the sleeping area. The walls, floors and ceiling of the sleeping area are insulated with 1 1/2" Styrofoam sheets. Interestingly, these folks suggest that the height of the dog house should be just 1-2" higher than the dog's height while in a sitting position. This makes for a rather low ceiling compared to most other plans out there but obviously the intent here was to keep things snug for heat retention. The plans include some helpful tables that list dog house dimensions for various dog breeds. Very well done.

My house took about 12 hours to build, and the materials cost about $100. But you don’t need to go to these lengths to build a comfortable house for your pet. You can build a basic version in an afternoon from plywood, lumber and shingles. It’s a simple, sound design that handles a dog of 70 pounds or so. All framing is cut to just four lengths, shown as dimensions A, B, C and D in the diagram above. To change the overall size of the house, just change the four framing dimensions. For my saltbox design, I simply extended the rafters and base frame on one side to create the covered porch shown in the image that kicks off this article.
