It is important to choose the right size pet door. It naturally has to be large enough to allow the pet easy access, but also as small as possible in order to keep rain, snow, and winds outside.
Most dogs duck their head and lift their legs when they go through a door, so the opening doesn’t have to be as tall as the dog. This can be confusing; it is tempting to install a pet door like we do a human door, with the opening starting at floor level. A dog door or cat door can generally be elevated.
