Installing a pet door into an overhead garage door can be tricky. You need to make sure that there is enough room in the lower panel for the door so that it will fit your pet. For smaller pets, this usually is not a problem. When you begin to look at pet doors for larger pets, you need to make sure to select a pet door that will give enough clearance so the dog will not have to slouch to go through the opening. This often can cause hip and back problems. Customers with taller dogs find many times that installing a dog door in the overhead garage door simply does not allow for enough room for the door required for your pet.
Also pay close attention to the profile of the selected pet door. You will have limited clearance
between the overhead door and the wall as it opens and closes. This clearance distance can vary based on how the door is installed as well as the type of door. Before ordering, visually check out this distance...if it appears that you have 3 inches or more as the overhead door opens and closes, then you should be fine with any of our recommended models below.
Make sure you pay particular attention to the exterior dimensions of the pet door. It is this dimension that needs to fit within the dimensions of your lower garage door panel. Very often these sectional panels are 18-22 inches in height.
