How to Choose the Right Size Dog Door Installation for Your Breed in Geelong

Tue, 20 Oct 2026 18:17:14 GMT

Choosing the right size dog door is one of the most important decisions pet owners face before booking a dog door installation in Geelong. Get it wrong, and you are looking at a frustrated dog and a wasted investment. This guide covers how to measure your dog and match that measurement to the right door size for your breed.

Why Size Is the First Thing to Get Right

A door that is too small forces your dog to crouch or squeeze through, putting stress on joints over time. A door that is too large lets in draughts, wildlife, and unwanted animals. Getting the size right from the start makes installation in Geelong a smooth, once-and-done job.

How Do You Measure Your Dog for a Door?

You only need two measurements: height and width.

Measuring Height

Have your dog stand naturally on a flat surface. Measure from the floor to the top of their shoulders (the withers). The flap opening should be at least a couple of centimetres taller than this so your dog can walk through without crouching. A common mistake is measuring to the top of the head. Shoulder height is what matters.

Measuring Width

Face your dog and measure across the widest part of their chest or hips, then add a few centimetres on either side. For long-haired breeds like Border Collies or Golden Retrievers, account for coat bulk, which can add a surprising amount to the measurement of the dog door installation.

The Step-Over Height

The step-over is the raised bottom edge your dog needs to clear. A lower step-over suits puppies, senior dogs, and short-legged breeds such as Dachshunds or Corgis. A step-over of around 75 to 125 mm is a reasonable starting point, adjusted for your dog's age and mobility.

Sizing by Breed Group

Use these as a starting point, then confirm with your actual measurements.

Small breeds (e.g., Chihuahuas, Pugs, and Miniature Schnauzers) Generally suit a small flap. Pugs and Bulldogs have wide, barrel-shaped chests relative to their height, so width is especially important.

Medium breeds (e.g., Beagles, Staffordshire Bull Terriers, and Cocker Spaniels): A medium flap is often suitable, but Staffies are compact and muscular and may need a wider opening than their height alone suggests.

Large breeds (e.g., Labradors, German Shepherds, and Weimaraners): Typically need a large or extra-large flap. Labradors are popular across Geelong and the Bellarine Peninsula and generally require a flap that accounts for their broader build as well as their height.

Extra-large breeds (e.g., Rottweilers, Great Danes, Bernese Mountain Dogs): Oversized flaps for dog door installation are available. Rottweilers in particular have wide chests relative to their height, making width just as critical as height.

Common Sizing Mistakes to Avoid

Sizing errors are more common than people expect. Watch out for measuring by weight rather than actual dimensions, using head height instead of shoulder height, ignoring coat bulk on long-haired breeds, overlooking step-over height for older or less mobile dogs, and assuming one size will suit multiple dogs without checking the largest dog's measurements. If you have more than one dog, always size for the largest.

Local Factors That Affect Your Choice in Geelong

Geelong's coastal location means many homes, particularly in Torquay, Ocean Grove, and along the Surf Coast, experience strong southerly winds and cool winters. A well-fitted flap seals properly and keeps your home warmer and drier. A door even slightly too large for your dog may not seal well. Choosing the correct size before installation means fewer adjustments and better long-term performance.

Many properties in established suburbs like Newtown, Belmont, and Highton have older door frames, timber doors, and decorative glass panels that affect which dog door installation method works best. Getting the size right first means your installer can recommend the most suitable fitting approach. Explore our dog door services to see the options available for different home types.

Can I Use My Dog's Weight to Choose a Door Size?

Weight gives a rough starting point but should not be your only guide. Body proportions vary significantly across breeds, so always take physical measurements as your primary reference.

What If My Puppy Is Still Growing?

It may be worth waiting until your dog is closer to adult size before booking an installation. If you do install early, sizing up slightly can accommodate growth, but a significantly oversized door may not seal properly for a small dog.

Do I Need a Different Size for Glass vs Timber Doors?

The flap size you need stays the same regardless of door material. However, installation method and fitting requirements differ between glass panels, timber doors, and security screens. A professional dog door installation expert can advise on the right product for your situation.

How Do I Know If the Door Is the Right Height Off the Ground?

Set the step-over at roughly one-third of your dog's shoulder height as a starting point, adjusting for dogs with mobility issues or very short legs.

What If I Have Two Dogs of Different Sizes?

Always size for your largest dog. Your smaller dog will have no trouble using a slightly bigger door, and your larger dog can use it comfortably without risk of injury.

Pet Door Installation in Geelong, VIC Rentals: What Tenants and Landlords Need to Know

Wed, 12 Aug 2026 19:47:49 GMT

North Geelong is an established suburb bordering the industrial waterfront of Corio Bay, with a strong mix of older brick veneer homes, weatherboard cottages, and post-war fibro houses. Many of these properties are rented, and their older aluminium screen doors, timber back doors, and single-skin walls are among the most common surfaces where pet door requests arise. Here is what the current rules say about pet door installation in Geelong, VIC.

What Victorian Law Says About Pet Door Installation in Rentals

Amendments to the Residential Tenancies Act in March 2021 confirmed that renters can make certain changes to a rental property without permission, provided the property can be returned to its original state at the end of the tenancy. Landlords must now have a reasonable reason to prevent tenants from installing a pet door, and consent cannot be withheld without justification.

Modifications allowed under the Residential Tenancies Act 1997 are generally limited to those that do not penetrate or permanently modify any surfaces, fixtures, or the structure of the property. Because cutting a hole through a door or wall is a structural change, tenants should always seek written permission before any pet door installation, regardless of how straightforward the job appears.

How to Request Permission From Your Landlord

If a tenant proposes to keep a pet on a rental property, they must apply in writing to their rental provider for consent. The rental provider must not unreasonably refuse such a request and will be deemed to have consented unless they apply to the Victorian Civil and Administrative Tribunal (VCAT) within 14 days of receiving the request.

For pet door installation, specifically include the door type, the proposed installation location, and how the property will be restored when you vacate. Keep a copy of all correspondence.

Reversible vs. Permanent Installs: Why It Matters in a Rental

Reversibility is the key factor in any rental modification. Landlords can only refuse changes that cannot be reversed, so the type of install you choose can significantly affect whether your request is approved.

Reversible Installation Options

Reversible or low-impact pet door installs are often the easiest to get approved. Common options in North Geelong rental homes include aluminium screen door inserts, where a replacement panel is cut to size and fitted within an existing screen door frame and can be swapped back at the end of the tenancy; sliding door panel inserts, where a secondary panel sits in the sliding door track beside the existing door with no cutting of the primary door; and removable flap kits for timber doors, designed for reinstallation with minimal visible repair once removed.

Permanent Installation Options

Permanent installs involve cutting directly through a timber door, solid panel, wall, or glass sliding door. These require stronger written consent and a clear restoration agreement. Under the Residential Tenancies Regulations 2021, landlords can request that tenants remove modifications and restore the property to near its original condition. If major modifications are made without agreement, the tenant may be responsible for restoration costs.

A skilled installer can often achieve a clean, near-invisible result that satisfies both tenant and landlord requirements when it comes to pet door installation.

Common Door Types in North Geelong Rentals

The age and style of housing stock in North Geelong means installers frequently work with three main door types. Aluminium security screen doors are common in post-1970s homes near Corio Street and are often the most tenant-friendly option, as replacement screen panels are readily available. Solid timber back doors are typical in pre-1960s weatherboard homes near the North Geelong railway precinct and can be professionally fitted and patched if needed. Sliding glass doors are found in many 1980s and 1990s brick veneer rentals and require a panel insert solution or specialist glass cutting, always with documented landlord approval.

Confirm door type and material with your installer before lodging your written request, as this detail helps your landlord assess the proposal more quickly.

What Landlords Should Consider Before Saying No

A landlord cannot unreasonably refuse consent for modifications that improve safety, energy efficiency, or accessibility. A pet door that allows an animal to relieve itself outdoors and reduces indoor damage may serve the landlord's interests by reducing wear and tear inside the home. In some cases, landlords may request an additional bond to cover potential restoration costs. The best approach is for the tenant and landlord to discuss the proposal and reach a mutually convenient agreement.

Pet Door Installation: Glass Door vs Timber Door

Mon, 27 Jul 2026 14:22:03 GMT

Choosing the right door material for pet door installation matters more than most pet owners realise. Whether you have a sliding glass panel or a solid timber entry door, the material affects how installation is approached, what products can be used, and how much complexity is involved.

Glass Doors and Pet Door Installation

Glass door installation requires specialist work. The existing panel cannot simply be drilled into on site. Instead, it typically needs to be removed and replaced with a custom-cut toughened panel that already has the aperture built in. Toughened glass is used because it handles the repeated impact of your pet passing through over time.

This process involves more steps than a timber job. Measurements are taken, the glass is manufactured off site, and a qualified technician returns to fit the new panel. The result is a clean, seamless finish that suits modern homes and sliding door set-ups common across Geelong suburbs like Highton, Belmont, and Armstrong Creek.

Glass installations are generally a better long-term fit for owner-occupiers, as the work is structural and less practical for renters who cannot make permanent changes.

What to Know About Glass Door Types

Not all glass is the same. Double-glazed panels, frosted glass, and floor-to-ceiling sliders each present their own considerations. Always confirm the glass type before proceeding, as this affects which pet door products are compatible.

Timber Doors and Pet Door Installation

Timber doors are generally more straightforward to work with. Installation typically involves cutting an aperture directly into the door panel and fitting a pet door unit using a standard frame-and-flap system. Solid timber and hollow-core doors both accept pet doors, though hollow-core doors may require additional framing around the cut to ensure a sturdy, weather-tight result.

For renters or those in strata properties, timber door installation can sometimes be reversed, making it a more flexible option. It is still worth checking your lease or body corporate rules before going ahead.

Geelong's coastal climate means draught sealing matters. A well-fitted pet door with quality magnetic or brush seals helps keep warmth in during winter, regardless of door material.

Solid Timber Versus Hollow Core

Solid timber doors offer a more stable substrate and tend to hold a pet door unit more securely over time. Hollow-core doors can work well for smaller pets, but larger breeds may need a reinforced fitting to prevent movement or flex around the frame.

Which Door Material Is Right for You?

The best choice depends on your home type, your pet's size, and whether you own or rent. Glass suits owners seeking a premium, low-profile result. Timber suits those who need a quicker turnaround or a more flexible installation. Either way, a professional measure-and-quote is the best starting point.
