How to Install a Dog Door

Purchasing a Dog Door

• Before heading off to the store to purchase your dog door, know EXACTLY how large a dog you’re dealing with. Don’t guess. Measure the height and width of your dog standing, then add two inches to both dimensions. This will help you determine the size (and eventually placement) of the door you’ll buy.
• Next, measure your exterior door to be sure the dog door you purchase will fit.
• Dog doors come in various sizes and prices, including some that can be installed inside your wall. Choose a dog door that best fits your situation.
