Best Way to Install a Dog Door in a Sliding Patio Door

Installing a dog door in a sliding patio door allows your dog to roam in an out without prompting your attention.  Based on the size of your dog along with your door's specifications you can easily install this door for you and your pets' convenience.  There is no longer the need for reconstruction to your door or door frame.

Before investing your time and money in this project please be aware that your door's track height fits the range of the door you have chosen, as there is no "standard" track height.  Another important factor is determining the size of the flap and rise needed for your dog, of course allowing room for growth if you have a younger dog.  After considering the size of the dog door it is a good idea to ensure humans have enough room to walk freely in and out. 

Depending on the manufacturer, you will have a choice of colors from white, satin or a very dark brown.  For a more uniform look with your existing door frame you can paint the dog door to match.

Depending on if your patio door opens from left or right will determine which side you install your dog door and you will be locking your patio door directly to the dog door. 

Installation is easy, and although no tools are necessary, you might need a screwdriver and screws if fastening to your door frame.

• Position your dog door inside your door frame.


• Check for gaps in the top, bottom and side.


• Adjust if necessary to the top and bottom of the dog door. 


• Secure by either the spring loaded device or you can semi-permanently fasten it by screwing it to the door frame.


• Close your patio door, checking it is completely sealed and flush to the dog door.


• Lock your patio door to the dog door.

Depending on your budget and if you have security concerns there is also the option of the electronic style as opposed to the manual style.  The electronic styles are also quick and easy to install using same steps as the manual style.  This upgraded style includes a motorized flap, a sensor to eliminate inaccurate signals along with sensor to program the flap for distance.
