Sizing Guide

What size house does your dog need?

Dog SizeUnlike people, dogs require smaller doors than what their total height is. For instance, a coyote's total height is between a spaniel and a Labrador Retriever (24 to 28 inches tall), yet his door opening is 8" to 10" in diameter. This is why Blythe Wood Works has developed the A-B-C Method for determining the ideal dog house size for your pet.

Dog Size

Dogs have to have an opening large enough to accommodate their width, but from a height standpoint all that is required is approximately 3” taller than the “A” measurement, which is the top of the shoulder to the bottom of his chest. Bigger doors are okay, but not necessary unless there is a physical requirement.

Remember, the first consideration for a proper sized doghouse is the door. He has to get in and out before any other considerations are made. If the dog's “A” measurement is 8 1/2”, the door height needs to be at least 11 1/2”.

This is why Blythe Wood Works has developed the A-B-C Method for determining the ideal dog house size for your pet.

The A-B-C Method

In the A-B-C method, there are three measurements that are needed to determine the size of a dog house. They are defined as follows:

ABC

A  The distance from the dog’s shoulder to the bottom of his chest

B  The distance from the dog’s nose to his flank, not including the tail

C  Distance from the top of the dog’s head to his toes


A. The door opening height needs to be at least 3 inches taller than the shoulder to chest measurement.

Example: If the "A" measurement is 10 inches, the door height opening needs to be 13 inches.

B: The width and depth of the house should be at least the "B" measurement (the distance from the dog's nose to its flank, excluding tail).

Example: If the "B" measurement is 30 inches, then the minimal size house should be at least 30" wide by 30" deep.

C: The "C" measurement is utilized to determine the correct dog house height at the peak. The minimal house height should be 1.25 x the "C" measurement (the distance from the top of the dog's head to his toes).

Example:If the "C" measurement is 23 inches, then 1.25 x 23 = 28 3/4 inches. The shortest dog house this dog could use would measure 28 3/4 inches from the peak to the ground.

Therefore, a dog of size A: 10" B: 30" C: 23" would require at least a Blythe Wood Works Large size dog house with a standard vinyl flap door or an upgrade Seal Safe door.

Please Note: The ABC formula calculates minimal sizing requirements. Larger than necessary houses are okay, but in extreme colder elements without our electric Dog House Heater unit, the extra space makes it more difficult for your dog to stay warm.
