Can You Put a Dog Door in Glass? (Explained!)

Yes, you can put a dog door in glass, but you will need to cut the glass which is best done by a professional with the right tools. If you don’t feel comfortable cutting the glass or hiring a contractor, you can also use a dog door panel in open sliding doors. Just make sure the panel fits securely in the opening and you fix that side of the sliding door in place so the dog door panel doesn’t fall out.

Dog doors may easily be installed just about anywhere. This includes glass, brick, interior doors, and more. Just decide where you want to put a door and check a local contractor — Just be sure to check with your insurance provider in advance, as additional premiums may be required for less convenitional installs.

Today we’re going to answer questions from other dog owners, such as yourself, in regards to dog doors. We’ll talk about costs, whether or not they are a security risk, and more. Let’s take a look at what people are asking the most this week on this subject!


How much does it cost to put a dog door in a glass door?

Costs will vary a bit depending on your door, but in most cases, you can expect a dog door installation in a glass door to set you back between $355 to $1250 dollars.

What needs to be done, is that the dog door size needs to be measured against the glass, so that a glazier can cut it and create a pane that incorporates the dog door or simply install it to the existing door. Keep in mind, you can also install dog doors in walls and this might save you a little cash if the glass rate seems expensive.

Can you put dog flap in glass door?

Yes, you could certainly install a dog flap into a glass door, though it might be more feasible to go ahead and upgrade to a nice, locking electronic model. This will help to keep other animals from using the door and help to keep drafts from coming into the house.

As glass door installation is a bit on the expensive side, it just makes sense that you go with a better grade of door if you’re going to be paying for a glass install anyway.

Can you put a dog door in a glass patio door?

Yes! Dog doors may easily be incorporated into a sliding patio door and as this takes very few modifications, this is a viable option for renters who want to install a dog door with minimal fuss and cost. Pre-fabricated options are often available, with only a simple removal of the old glass and refitting required.

Can you cut a glass door for a dog door?

If you have a single pane setup, rather than a double pane, then cutting the glass is quite easy to do. If you aren’t confident with the process, simply measure out the dog door against the glass and hire a glazier. They can do the cutting and installation for you without risk to your expensive glass door.

Can you put a dog door in a brick wall?

A dog door can be installed into a brick wall, but you would need specialized masonry tools such as a reciprocating saw and a hammer drill to get the job done.

It is best to go with a professional, as their work will be insured, and that way you can get the door installed properly without worry of damaging your wall. Also, be sure to check with your insurance provider, as a wall-door might require additional premiums to retain full insurance coverage.

How big should a doggy door be?

The doggy door that you install should be at least 1 inch taller than your tallest pet. You also want to make sure that the step inside of the dog door is no higher than 1/3 of your smallest pet’s overall height.

Between these two measurements all of the pets in the house should be able to easily use the new dog door!

What is the largest dog door?

Barring a custom installation, the largest pre-fabricated dog doors will typically measure 12 inches by 23 inches. This is considered the ‘extra-large’ size and it is a good fit for large breed dogs such as Rottweilers, Great Danes, Sheepdogs, and more.

When in doubt, just remember that a dog can use a door that is too large for them, but they often cannot use one that is too small – aside from the problem squeezing inside, the smaller doors simply aren’t rated for a larger dog’s weight.

How do you permanently seal a dog door?

While you can use caulk, weatherstripping, or even custom-cut wooden panels, this still leaves the door with a weak point that might still be easily identified under the new paint. The best option is to simply replace the door if you no longer need the doggy door.

This is especially true with hollow doors, as the installation of a dog door can compromise their overall integrity, making replacement the most sensible option.

Are dog doors a security risk?

Dog doors do pose a potential security risk, especially with larger doors. These might allow a thin-framed burglar to simply squeeze inside, or they might be able to reach in and unlock the door. Additional security is thus a good idea if you will be installing one.

Motion detectors and security cameras are inexpensive and effective, and you can even install a security alarm in the door itself for when you and the dog are not in the home.

Do they make doggy doors for large dogs?

Doggie doors come in a number of prefabricated sizes, ranging from small which can fit dogs like Chihuahuas, Yorkies, or Shih Tzus up to extra-large, which are a good fit for Rottweilers, Great Danes, Sheepdogs, and other large breeds.

If you aren’t sure which size to select, then get one which is larger than what you need. Your dog can still easily use it, while a door that is too small will be either useless or quickly damaged with regular use.

How do I stop rain from coming in my dog’s door?

When purchasing your dog door, you can look for brands that boast airtight seals, or if you already have a flap style dog door then you can simply hang magnets on the bottom of the door and install a metal strip.

The magnets will hold fast, attracted to the strip when the door is not in use, and this should minimize drafts and the chance of rain coming inside through the door.
