Pet Doors to Install in French Doors

Do You Need to Install a Pet Door Through Your French Door?

Great, we have pet doors for you! Is the glass in your French Door made of individual pieces, or one piece of glass?


Custom Pet Door Options Available to Fit Your Door

Multiple pieces of glass, individually framed.

If one or more pieces of glass can be removed, you can order a custom sized pet door to fit inside the hole that is created.

If you have a large dog you might be able to replace more than one piece of glass, or cut into the door frame to have your french doors with doggie door installed.

Here are some examples:

One solid piece of glass with decorative grid-work.

If you have one solid piece of glass in your door you will need to have a glazier cut a new piece of glass for you with a hole for the pet door you choose.

Or you can replace the entire piece of glass with a Through the Glass Pet Door.

Important Things to Note When Installing a Pet Door Through a French Door

Ensure that the pet door will be installed at the right height for your pet; it is a good idea to measure your pet to determine the size required. Your pet door can take up the space of one grid, more than one, or it could even cut into the wood below the glass if possible. If you are working with a glazier who can cut the glass, you can virtually use any size pet door that best suits your home and pet.


Q. How to install a dog door in a glass french door?

A. What you Need:

  • Professional installer (highly recommended)
  • Individual panes of glass
  • Pet door frame and flap
  1. Measure your pet from feet to shoulder to gauge the correct flap size needed
  2. Be mindful of how high your pet door might be installed since glass on french doors tend to be quite high
  3. Remove the desired glass pane
  4. Measure the opening of the hole
  5. Use these measurements, you can order your custom dog door for your french door
  6. Contact your installer to place the pet door in

For single panes of glass:

  1. Measure your pet from feet to shoulder to get the correct flap size
  2. Contact a local glazier who can cut glass for pet door installation
  3. Using the glass thickness, you can determine which dog doors can fit (pet doors have certain thickness ranges)
  4. Have your glass piece removed and cut by your glazier
  5. Once the dog door is installed, your glazier can put everything back together


*Depending on the type of glass you have, it may not be possible for a glazier to cut directly into it; in which case, an In the Glass Unit is highly recommended.
