A dog door allows your pet the freedom to choose where she wants to lounge or play, or to take a potty break without having to wait for you to notice her need. Unless some management measures are in place, there are some heightened risks associated with dog doors, however. A dog door can let more than the dog enter or leave your house, and your freedom-loving dog can get lost or injured if her dog door doesn't open into to a securely fenced area. A door with a built-in security panel gives you more control, and some door styles respond only to an electronic "key" worn on your pet’s collar.

Measure the height of your dog from the floor to the lowest point of her chest or abdomen -- whichever is bigger -- and jot down the number as the "step-over height." Next, measure from the floor to your dog's shoulder, add an inch or two, and record that number as the "maximum height." Finally, measure her widest point, usually the width across the shoulders or hips. Take whichever is the largest number, add 2 inches and record it as the "minimum width."

Find the center of the door from side to side at the bottom, and make a light pencil mark. Measure and mark a second point in the center of the door higher at approximately the height of your pet’s shoulders, and attach a length of masking tape vertically between the marks. Draw a line between the points on top of the masking tape to keep from needlessly marking your door.

Measure up the line from the bottom of the door the number of inches you recorded as the "step-over" height. Make a horizontal guideline across the door at that height. Use a carpenter’s square to ensure that the line is perpendicular to the vertical line you drew in the previous step.

Warnings

  • Small children can fit through very small spaces, and may use the pet door to get to places where they are endangered. This poses a special hazard if your dog door opens to an unfenced yard or if you have a pool. Security is reduced and heightened parental supervision is required if you install a pet door.

Tips

  • The Partnership for Animal Welfare recommends never leaving your dog alone in the house without securing the pet door.
