It can be difficult to find a pet door that will match your old one exactly. First, you'll need to measure the cutout hole in your door. Note that this is the cutout in the door, not the pet door frame. Next, pick a door that is closest in measurement. You can find the dimensions for our pet doors in this chart.
You might need to cut the hole in your door a little bigger to accommodate a slightly larger new door. To replace it with a slightly smaller door instead, add additional pieces of wood to the inside of the hole.

Most pets will learn to use the door with a few short training sessions. However, some pets can take a little longer to become comfortable and more confident using the door. The most important rule is to be patient with your pet. Let your pet work out for himself that he can go through the pet door. With a little patience and training, you and your pet will soon enjoy the freedom your new pet door provides.
Helpful Tip: Try treats or toys to encourage your pet to go through the pet door.
