Most often we use a dog's weight to determine the size needed. Unfortunately some dogs are tall and skinny, i.e., Doberman Pincers, so height requirements must also be considered. Ideally, the house needs to be just big enough for the dog to enter, turn around, and lie down. Anything larger is at your discretion, but during the colder months body heat retention is sacrificed.
Choosing the correct size house ensures the comfort for your dog. If you live in a region with severe winters, bigger is definitely NOT better. If your region has extremely mild winters, a house "larger than necessary" does not present a problem.
In our experience with dog houses, the A-B-C method is usually the most accurate for determining the correct size of doghouse for your dog.
The door height opening should be no less than three fourths (3/4) of the dog's shoulder to ground measurement. LARGE doors aren't necessary, and can let in more of the elements than necessary. Dogs typically "duck" to enter a dog house.
Example: If dog's "A" measurement is 19 inches, the door opening needs to be at least 14 inches tall.
The width and length measurement of the house should be the same as or no more than 25% larger than (B), the nose to flank measurement (Tails don't count).
Example: If the dog's "B" measurement is 24 inches, the doghouse width and length should be no less than 24 inches and no more than 30 inches.
The height of the doghouse should be at least 25% (no more than 50%) taller than the height of the top of the dog's head to his toes (C). Again, this house measurement (C) can exceed the dog's total height (C) up to 50% and still maintain a good body heat retention factor during cold months.
Example: If the dog's height is 22 inches, then the total doghouse height should be approximately 28 to 33 inches.


Good luck to you !!!
