Dog House Sizing Guide

Making sure you purchase an appropriately sized dog house for your pet is more important than you might think. The right size will make your dog feel safe and secure. That's why taking the time to measure your dog and determine the best size of dog house for him makes a world of difference when shopping. Once you figure out what size you need, you can then shop our amazing selection of dog houses.

To determine dog house size, your dog’s weight is a good starting point. However, if your breed is between sizes or your dog’s weight doesn’t accurately reflect his or her body size, it’s best to measure your dog. Ideally, the dog house needs to be just big enough for your pup to enter, turn around, and lie down. Anything larger is at your discretion, but during the colder months, body heat retention is sacrificed if the dog house size is too big for your pet. To measure your dog and correlate it to its appropriate dog house size, follow these easy steps.

Measuring Your Dog


Dog House Door Size

Measure your dog from shoulder to ground. 75% of this measurement equals the size of the dog house door you should look for. Large doors aren't necessary - dogs typically lower their heads to enter a dog house.

Shoulder to Ground x .75 = Dog House Door Size

Example: If your dog's shoulder-to-ground measurement is 19 inches, the door opening needs to be at least 14 inches high.


Dog House Height

Measure your dog from head to ground. Add at least 25% to this measurement to determine the optimum dog house height. Don't add more than 50% of the measurement to allow for body heat retention.

Head to Ground + (Head to Ground x .25-.50) = Dog House Height

Example: If the dog's height is 22 inches, then the total dog house height should be approximately 27.5 to 33 inches.


Dog House Width & Length

Measure your dog from nose to flank - do not include the tail in the overall measurement. Add 25% to this measurement to determine the best width and length of dog house.

Nose to Flank + (Nose to Flank x .25) = dog house width and length

Example: If your dog's nose-to-tail measurement is 25 inches, the dog house needs to be at least 31.25 inches long and wide.
