How to Install a Dog Door in a Glass French Door

Running around in the front yard and chasing the neighborhood cats is one of the basic canine pleasures that you would not want to deprive your dog of.

But what about the times you are at work? While you obviously cannot leave your house door open when you are not around, you cannot just lock your dog outside your house for hours either!

The perfect win-win solution is to install a dog door in your house door through which your furry friend may easily go in and out of your house as they please. Installing a dog door in a usual wooden door is very simple. However, the task may seem a bit challenging when you have a glass French door.


Determining the Type of Your French Door

To begin with, determining the type of your French door is the first step to installing a suitable pet door for your dog. Generally, there are two types of glass French door:

1. One Piece of Glass with Grid-work

If your door has one solid glass piece, the process of installing a doggie door in a glass French door may prove to be a bit difficult.

The reason is that you will need to have a new piece of glass cut with a hole to fit the dog door of your choice.  

2. Multiple Panes of Glass, Individually Framed

If your door has individual panes of glass, you can simply get one or more glass pieces removed and replace it with a custom-built dog door that perfectly fits inside the hole you have created.

The number of glass pieces that you will have to get removed depend on the size of your dog. For a large dog, you will have to remove more than one glass panes or perhaps cut into the doorframe to accommodate a doggie door in the French door.

Installing a Dog Door in the Glass French Door

Based on the type of French door you have, the process of dog door installation may vary  greatly. Ideally, your dog door may take up the space of one glass piece or more than one. It could even cut into the doorframe below the glass if need be. Considering this, it might not be an ideal DIY task that you would want to do. You may find it challenging to cut the glass or amend the door frame to fit the dog door in.    

Let us go into the detail of the installation process for each.

The best way to install a dog door in a single-pane French door is to replace the glass pane with   one that has a dog door installed at the bottom. You can also get the existing glass pane removed, get the desired dog door installed in it and get it put back.
