Dog Doors In Glass, Sliding and Patio Doors

A dog door fitted into glass gives your pet the run of the yard without leaving a door open all day. We supply and install pet doors across Sydney into sliding glass doors and patio doors, stacker and bi-fold doors, fixed glass panels, side lights, French doors and security screens.

Whatever door you have, the first question is the same: can a pet door go into it, and does the glass have to be replaced to do it? Most of the time it does not. Find your door type below, or send us a photo and we will tell you.

What type of door do you have?

Start with the door you have. Pick the one below that matches it.

Whether we cut the panel you already have or fit a new one comes down to the glass in your door and the size of your dog. Laminated glass with a small or medium dog is usually a cut, on site, in one visit. Toughened glass, or a large dog, needs a new panel with the opening already in it.

Not sure which you have? Send us a photo of the corner of your glass and we will tell you, or call 0421 575 229.

Dog doors for sliding glass and patio doors

The most common installation we do in Sydney, and the one people worry about most, because the door has to keep sliding afterwards. It does. We have been fitting pet doors into sliding and patio doors since 2011.

Into the sliding panel

Our pet doors use a slimline frame designed to pass between the glass panels as the door runs, and they need a gap of 6 to 7mm to clear properly. Where the gap is tighter, we can modify the frame or fit a door stopper so the door still runs smoothly and the pet door is never caught.

Into the fixed panel instead

Most sliding and patio doors have one panel that slides and one that does not. Putting the pet door into the fixed panel takes it out of the moving part of the door altogether: nothing to catch, no change to how the door runs and no restriction on how far it opens. Where the fixed panel suits your pet, it is usually the better installation, and we will say so.

Dog doors for fixed glass panels and side lights

A fixed panel is a pane that does not open: the still half of a sliding door, a side light beside your front or back door, or a run of full height glazing. It is often the tidiest place to put a pet door.

Nothing moves, so there is no mechanism to work around, no clearance to allow for and no effect on how the door itself operates. If you have a side light next to the door your dog already waits at, that is very often the answer. Have a look at the gallery of finished installations.

Stacker, bi-fold, French doors and security screens

Stacker and bi-fold doors

Stacker doors slide several panels back on top of each other and bi-fold doors concertina back against the wall. Both can take a pet door, and the approach is the same in each case: we look for a panel that stays put, normally the fixed end panel on a stacker, or the single access door on a bi-fold. Keeping the opening out of the moving panels leaves the mechanism working exactly as it did. Where every panel moves, we assess the track, the weight of the panel and the glass type first, and some bi-fold panels are too narrow to take a large pet door without compromising the frame.

French doors

A pair of hinged glass doors, usually with a large single pane in each. Because they are hinged rather than sliding there is no track or clearance to design around, so the installation is generally straightforward. There is more on our French door dog doors page.

Security screens and flyscreens

Where a glass door has a security screen or flyscreen in front of it, the job needs two openings that line up, with both doors still moving independently of each other. We install into Crimsafe and similar security screens as well as standard flyscreen, and we fit both openings in the same visit. If your job is screen only, with no glass involved, our screen dog doors page covers that.

Can your glass be cut, or does the panel need replacing?

Whichever door you have, there are two ways to fit a pet door into glass.

  1. Cut an opening into the glass you already have.
  2. Replace the whole panel with a new toughened panel, manufactured with the opening already cut.

Which one you need comes down to two things: the type of glass in your door, and the size of your dog. If you have laminated glass and a small or medium dog, we can usually cut the existing panel on site. It is faster, cleaner and cheaper, and you keep the glass you already paid for. If you have toughened glass, or a large or extra large dog, you will need a replacement panel, because toughened glass cannot be cut once it has been toughened.

Most of the enquiries we take come from people who have been told the panel has to be replaced. Often it does not. If you are not sure what you have, send us a photo of your glass and we will tell you.

We cut glass on site

Cutting a pet door opening into a panel that is already installed, standing upright in its frame, in someone’s home, is a specialised job. A glazier is trained to replace glass, and can cut a sheet laying flat on a factory bench, with the right table and the right conditions. Cutting that same glass vertically, in a frame, in a hallway, with furniture either side and no second attempt, is a different skill, and not every installer or glazier is set up for it. Recommending a replacement is the safe commercial choice for a business that cannot cut. It is also the more expensive option for you. We have specialised in cutting glass on site since 2011 and we carry the tools to identify, score, separate and finish a panel in a single visit.

Is it safe to cut laminated glass?

We hear this one constantly: “you cannot safely cut laminated glass.” That is not correct. Laminated glass is made with a clear interlayer bonded between two sheets, so if the panel cracks the pieces generally stay stuck to that interlayer rather than falling out of the frame. It is the same property that makes laminated glass good for security.

None of that makes it unbreakable. Laminated glass can still crack, usually from one of three things:

  • Sudden impact. A child kicking a ball at the door, someone knocking into the glass, heavy pressure on the panel.
  • Heat and prolonged direct sunlight, particularly a west facing door through a Sydney summer.
  • Poor preparation of the cut edge, which is the one nobody mentions and the one that comes down entirely to the installer.

Prepared properly, a cut laminated panel is sound. Prepared badly it will fail. Laminated glass we cut on site: 6.38mm, 6.50mm, Hush laminated, 8.38mm, 8.50mm, 10.38mm, 10.50mm, 12.38mm and 12.50mm. Price varies with the thickness of the glass.

When we will not cut your glass

Not every panel can be cut, and being able to cut glass also means knowing when not to. Before any work starts our technician looks at the size of your dog, movement in the glass, how much direct sunlight the panel takes, whether the door sits in a high impact area such as a main thoroughfare or a children’s play area, and whether the panel is oversized. If our technician judges the cut unsafe, we will not carry it out. We would rather lose the job than take your money for an installation likely to fail, and we will tell you what we would do instead, which is usually a replacement panel.

Toughened glass: replacement, not cutting

There is one rule with toughened glass and it has no exceptions. Toughened glass cannot be cut once it has been toughened. Attempting to cut or drill it will shatter the entire panel. So if your door is toughened, the pet door arrives in a new panel: we measure your existing glass, have a new toughened panel manufactured with the opening already cut, then remove the old glass and fit the new one. That costs more and takes longer, both for the same reason, because you are buying a complete new panel and it has to be made before anyone can install it. There are also limits on how close the opening can sit to the edge of a toughened panel, which rules out some combinations of door and pet size.

Large and extra large dogs

For large and extra large dogs we generally recommend a toughened replacement panel, whatever is in the door now. A big dog pushes a lot of weight through a pet door several times a day: constant movement, pressure and impact around the opening. The bigger the dog, the bigger the opening has to be, and the more glass comes out of the panel. We would rather specify the glass for the job than cut a panel that was never meant to carry it.

How we measure and assess

Every installation starts with an assessment of the door you already have: the type of glass, how it is fixed, how the door operates, how much sun the panel takes, and whether your council requires toughened glass for that opening, which applies in some bushfire prone areas. We measure and recommend before we quote, and the quote reflects the door in front of us rather than a standard price for a standard job. The same approach applies across our dog door installations in timber, screen and French doors, and to cat doors in glass.

Laminated or toughened glass, which is actually better?

Neither. They are built for different jobs.

“You can only have toughened glass” is not true

Where a door or side panel requires safety glass under the Australian standards, both Grade A toughened and Grade A laminated glass comply. AS/NZS 2208 is the standard that sets what counts as a safety glazing material, and laminated glass meets it. Toughened is not the only compliant option.

Laminated glass Toughened glass
Can a pet door be cut into it? Yes, on site No, the panel must be replaced
When it breaks Stays bonded to the interlayer Shatters into small blunt pieces
Security Hard to get through, the interlayer holds it together Leaves the frame in one go
Noise insulation Better Standard
UV transmission Significantly reduced Standard
Impact strength Good Much stronger than annealed glass
Best suited to Small and medium dogs Large and extra large dogs
Cost for a pet door Lower, you keep your glass Higher, a whole new panel

So which one should you have?

A question we get often: “we are in a new build so the glass is toughened, that must be better, isn’t it?” Not necessarily. Toughened is common in new builds because it is what the builder specified for that application, not because it beats laminated across the board. If you already have good quality laminated glass, do not assume that swapping it for toughened is an upgrade. We look at the glass you have, the dog you have and what the installation actually needs, then tell you which option suits.

FAQs Got Questions About Installing a Dog Door in Glass?

Yes. Toughened glass cannot be cut once it has been toughened, so we replace your existing panel with a new toughened panel, manufactured with the pet door opening already cut. It is a good option for large and energetic dogs.

They are built for different jobs and neither is automatically better. Toughened is stronger against impact and breaks into small blunt fragments, but it cannot be cut once it has been made. Laminated stays bonded together when it cracks, insulates better against noise and UV, and can be cut on site. Which one suits you depends on your door, your dog and your priorities.

Not always. If your door contains laminated glass and meets the correct safety and thickness standards, we can usually cut directly into the existing panel onsite. This is a quicker and more cost-effective option. If the glass is toughened, it cannot be cut once manufactured. In that case we remove the original panel and replace it with a custom-cut toughened glass panel that includes the dog door.

Absolutely. Our dog doors for sliding glass doors are designed for seamless integration. If needed, we can modify door frames or install stoppers to maintain smooth operation.

We offer glass dog doors suitable for dogs of all sizes, from small breeds to large working dogs. The best option will depend on your glass type, door layout, and your pet’s measurements. If you are unsure which size suits your home and dog, contact us and our team will guide you through the options.

If your door has laminated glass that meets safety and thickness requirements, we can often cut the panel onsite, which makes the installation quicker and more cost-effective. For toughened glass, which cannot be cut, we measure and replace the panel with a custom fabricated one. That takes longer, depending on glass availability and scheduling.

Yes, we supply and install microchip pet doors for glass panels. These offer added security by only allowing access for your registered pet.

Yes. All installations include a 3-year workmanship warranty, and our products are backed by manufacturer guarantees for long-term peace of mind.

No. Our pet doors for sliding doors use a slimline frame that passes between the glass panels, and they need a gap of 6 to 7mm to clear. Where the gap is tighter we modify the frame or fit a door stopper so the door still runs smoothly. If your door has a sliding security screen as well, we line up an opening in both.

Not always. A glazier is trained to replace glass, and can cut a sheet laying flat on a factory bench. Cutting a panel that is standing upright in its frame in your home is a different skill, and not every glazier or installer is set up for it. It is the reason so many customers are told the whole panel has to be replaced.

Not necessarily. Toughened glass is common in new builds because it is what the builder specified for that application. Laminated glass has real advantages of its own on noise, UV and security, and it can be cut on site, which toughened cannot. If you already have good quality laminated glass, replacing it with toughened is not automatically an upgrade.

Exceptional service, product and extremely quick turn around. Left an enquiry this morning. One hour later Alex called. 30 minutes later Allen installed my pups door in the crimsafe fly screen. Thanks so much. Might be back in winter for the glass door one too! One stoked owner. 😃
Response from the owner:Now that's the kind of turnaround we love! Enquiry in the morning, pup sorted by lunch. A crimsafe screen is a great spot for a pet door. So glad you're happy with it, and we'd be keen to sort the glass door one for you come winter. Thanks so much for the review! 😃

We had put getting a pet door in the “too hard / too expensive” basket for a long time, but finally decided to go for it. Sydney Paws Pet Door were fantastic from the start. Super fast responding to our enquiry and getting a quote through, really reasonable pricing, and they were able to come out to the Central Coast in good time. It was installed today and we’re really happy with it. The product is great and actually looks really good too. Really happy we finally got it done. Great service, great product and definitely recommend!
Response from the owner:Love this Tim! So glad you finally pulled the trigger after it sat in the too hard basket. Good pet doors shouldn't cost the earth, and we're stoked you're happy with how it looks. Enjoy the Central Coast sunshine with the new setup!

Alex was awesome- professional and really skilled at installing and communicated the pros and cons of using different doors. Really loves and cares about what he does and spent the time to help us retrain a 14 year old dog who is semi blind and deaf to use the door in our new home we just moved into. I would have had no idea what to do had he left without helping me train Max. By the afternoon Max was using the door all by himself. Highly recommend to anyone looking for an installer who truly cares
Response from the owner:Thank you Jenny, what a kind review. Helping Max learn the door at 14, even semi blind and deaf, is exactly the sort of thing Alex loves doing. So happy he was using it by the afternoon. Give Max a pat from us!

8 months ago we had our pet door added to our house. Summer was amazing in getting our appointment arranged. Alex arrived on time and installed our new pet door quickly and efficiently. He gave us great training on how the door worked and patiently showed our fur babies how to use the door. Our boys use the door all the time, often at running speed. The door still looks great and is as strong as the day it was installed. Highly recommend Summer, Alex and the team for your pet door solutions.
Response from the owner:Thank you Pamela! Eight months on and still going strong at running speed says a lot about a good install. The team appreciate the shout out. Enjoy the freedom, boys!
Excellent job done Alex. Thank you for the lovely services
Response from the owner:Thank you, Shyamalee! We really appreciate your kind words — Alex will be so pleased to hear you’re happy with the service. It was a pleasure helping you! 🐾

I can’t recommend Sydney Paws Petdoor enough. I had no idea what I needed or wanted and Summer was very helpful sending me information and pics of options as well as set pricing that made the whole process super easy. Alex came same day and did a fabulous job. He’s a super nice guy and gave me all the pros and cons about the two places I had chosen as options for the door to be installed which made it easy to determine the best solution. He even did some training with us and our dog and talked us through the best way to get him to use it.
Response from the owner:Thanks so much, Tamara! We’re really happy we could make the process simple and help you choose the best option for your home and your dog. Alex always enjoys walking owners through the pros and cons and helping with the training too. We appreciate the lovely feedback and recommendation! 🐾

Summer and Alex are an absolute dream team to deal with – I can’t thank them enough for squeezing my booking in and making the installation during the consultation. Could not be happier and Billy 🐺 took to the door like a natural (which is awesome if you know how stubborn huskies are at the best of times) Thank you for making our day with the smooth and tidy fitting and installation… 5 stars ✨ Sydney Paws Petdoor
Response from the owner:Thanks so much, Mark! We love hearing this — Summer and Alex will really appreciate the kind words. So glad we could fit you in and get everything sorted on the spot. And Billy 🐺 taking to it straight away is a huge win (especially for a husky 😄). Thanks again for the recommendation!
