How to Measure Your Dog

Choosing the correct size for your pet door is crucial for both your pet's comfort and the longevity of your pet door investment. To measure your pet, first measure the width of the chest and the hips. Add one or two inches to these measurements. Then measure the height, from the bottom of the chest or belly to the top of the shoulders. Also add one or two inches to this measurement. With these dimensions, as well as the weight of your pet, you can choose a pet door that is perfect your pet.
