    The Dogwalk® Glass Fitting Dog Door is manufactured from 100% high quality, high impact (PC) Polycarbonate. It is designed to fit single, double glazing and sliding windows and doors. To reduce the problem of broken flaps, associated with some other brands of dog doors, it has the added feature of the flap being able to swing higher.

    Glass cut-out size

    X = 385mm diameter +100mm glass tolerance so overall width of glass must be 485mm.

    If you do not have 485mm in the width of your glass this product will not fit. Before purchasing we highly recommend you consult a qualified glazer.

    • Overall size: 430mm x 451mm
    • Application: Glass fitting (3mm – 32mm)
    • Pet size: Medium to semi-large dogs
    • For sliding doors: The G-DDC protrudes 15mm on the inside and 24mm on the outside of the door its connected to. Please ensure enough clearance for sliding doors to pass the pet door.

    Manufactured entirely from high impact virtually indestructible (PC) Polycarbonate

    When you are purchasing a cat flap, please ensure: -

    • To select the most appropriate cat flap for your cat’s size, weight and needs.
    • We recommend that customers use the flap sizes to cut a hole in a cardboard box to see if the cat/dog will fit through it ok.
    • It is vital that you are confident that your cat flap purchase will fit in the desired place in your home. For example – if it is a glass installation, is the glass wide enough?

    Please note: the pet door cannot be installed into an existing tempered glass or double glazed window. The glass panel would need to be replaced with the hole already cut at the time of manufacture for the pet door to be installed.

    We recommend that customers use the flap sizes above to cut a hole in a cardboard box to see if the cat/dog will fit through it ok.

    Ask a Question
    • Hi. If there are lockable catches on each side, what is to stop someone from unlocking it from the outside?

      Hi - the plastic catches are inside the home - on the left and right hand side of the flap. Thanks.

    • I have a large jack russell. Weighing in at approx 12kg & a smaller yorkie. Would this size be suitable?

      I would think so - it is a flap size of 300mm (W) x 270mm (H). We recommend cutting that out on a box to check that the dogs will fit through ok. Thanks.

    • Hello, do you sell this door one size smaller (with a flap size of 240mm x 215mm)?

      We don't, sorry. That size hasn't reached the UK yet as far as I am aware.

    • It says on your website that the door cannot be installed in existing glass but that the glass panel needs to be replaced with the hole already cut at the time of manufacture. We were planning to simply get the hole cut by a glazier into an existing glass panel. Could you please let us know why this is not possible?

      No, you can't cut into a double glazed unit as it would just shatter and the seals would be broken. I have also cut and pasted this from the Cat out of Glass website: -

      `As cat flap fitters we are frequently asked if a cat flap can be installed into existing double glazing units?

      Regretfully, double glazing cannot be modified as the glass is toughened, airtight and made to measure. A brand new unit will be required. 

      This new double glazed unit for your cat flap is then made by a double glazing manufacturer.

      They will cut out a hole for the cat flap in both pieces of glass before they go to be toughened and made into a double glazed sealed unit.`

    • How low in the door can it be?

      It needs a 385mm cut out in the glass, and the hole has to be 50mm up from the bottom of the pane to comply with building regs. Thanks.


      I think it will be week commencing 10th May - the ship has been delayed several times sadly.

    • When will the Pet Tek clear glass fitting dog door- transparent be back in stock? Will I be notified?

      They are back in stock again now Louise, you should be able to order. Thanks.

    • Can I lock it at night

      Hello - yes, there are 2 plastic catches, one on each side of the flap that you can use to keep it closed at night time. Thanks.

    Great customer service

    I ordered the wrong size in error, but the company were more than happy for me to return the item. Very helpful and efficient service !

    Glass door dog flap

    It took a while for the glasier to fit the flap in the door (which had to be removed and taken to the shop). However, now the glass door has been rehung - it looks great, and very secure. Our two springers - one old 15 yr old, and a 4year old were a bit wary and needed coaxing through the flap- but i'm sure they'll get used to it. Great product, but does needs a professional glasier to fit.

    Great dog door

    I bought pet door as a replacement for one I’ve had for a few years in a double glazed patio door, the change over was quick and without any hassle. Can’t recommend these doors enough, easy to use for my little dog and very unobtrusive. Like this so much I’ve put one in a new house I am moving to soon.

    Dog flap

    Haven’t actually had it installed yet as moving into a new house. It looks like it will do the job nicely just need to find a local firm that can be bothered to ring me back to install it in a new piece of double glazing. Will update my review when I finally get to see the dogs use it.

    Superb product

    This was bought as a replacement. The original was fitted by the company who cut the glass panel, but this time I changed it. Really simple to do. Great quality product. Initially out of stock but the company emailed me when it was back in stock and helped me order it too. Very helpful
