Best Dog Door & Pet Door: Buyer’s Guide & FAQ

1. Consider Manual vs. Electronic Dog Door

  • Traditional Manual Dog Door

Traditional manual dog doors come with a frame made of usually hardened plastic or aluminium.

They can come with one to three dog door flaps made of plastic or vinyl, that is clear or tinted.

They can be door mounted, wall mounted or full height doors and panels that sit in a glass and aluminium sliding door track.


  • Electronic Dog Door/Smart Dog Door

The cheaper type of electronic dog door is made of a hardened plastic with a hardened plastic flap.

The flap is operated by a smart key with batteries which allows you to lock or open the door electronically or automatically.

Other cheaper electronic dog doors work with existing microchips.

There are also more expensive high tech electronic dog doors that are motor driven and allow you to be much more specific with the access and exit settings, and they are smarter when it comes to allowing your pet in and out.


  • Which is better – Manual dog door or electronic dog door?

The truth is that there aren’t any perfect electronic pet doors on the market at the moment – especially for large dogs.

When you pair that together with the fact that there is an upkeep cost (batteries, transmitters and repairs for door electronics), these doors can be very expensive and more effort and time than they are worth in the long run.

If security is a big thing for you, you are better off getting a manual dog door with a sliding security panel.

Manual dog doors are generally a one off cost, and once they are installed, you don’t have to worry about repairs or replacing anything.


2. Consider Type of Dog Door

Apart from the two main types of dog doors above (manual and electronic/automatic), there are specific dog door types to consider:

  • Regular Dog Door For Door Mounting
  • Weatherproof Dog Doors For Hot or Cold Weather
  • Electronic/Automatic Dog Doors
  • Aluminium Framed Dog Door for Wall Installation
  • Dog Door That Installs into Sash Window (e.g. Ideal Pet Products Aluminum Sash Window Pet Door)
  • Dog Door That Fits Vinyl Patio Doors ( e.g. Ideal Pet Products 150 Series Vinyl Insulated Pet Patio Door)
  • Patio Panels for Sliding Glass Doors (full height portable dog doors that install into the sliding door track)
  • Door Mounted Dog Doors For Large and Extra Large Dogs (usually by a company called Plexidor)
  • Security Based Dog Doors With Secure Locking Screens and Panels


3. Consider Dog Door Sizes

Dog and pet doors can range in opening size, but generally a standard dog door will be:

  • Small – 5 1/8″ W x 8 7/8″ H
  • Medium – 8 1/8″ W x 12 7/8″ H
  • Large – 10 1/8″ W x 16 7/8″ H
  • Extra Large – 13 5/8″ W x 24 3/8″ H


Dog doors for sliding glass doors and patios will be full length panels (much taller than the above standard dog doors) and doors that fit into the sliding door track. 


4. Measuring Your Dog For A Dog Door

It’s important to follow the manufacturer’s directions on measuring your door, wall and pet for knowing which size pet door to order.

But in general, you’ll want to complete four measurements (five for full length dog doors):

  • Height of Your Pet (paws to top of shoulders, and bottom of chest to top of shoulders) – add two inches to the shoulder height of your dog for your dog door opening size
  • Width of Your Pet (at shoulders)  – add two inches to the width of your dog for your dog door opening size


Most online resources will tell you these two measurements and leave it at that. However, there are two other measurement you have to carry out…

  • Weight of Your Pet – Most manufacturers will also rate their door for a dog of a certain weight – so check the what weight of your dog is and check the manufacturer’s design instructions (usually in pounds).
  • Thickness of Door or Wall – the average dog door is built to be installed in doors 1-1/4-Inch to 2-Inch thick. Although, some have a telescoping feature to fit to different thicknesses.
  • Track to track height – for full height dog doors for aluminium glass sliding door installs.


Note that if you have two or more dogs or pets, you’ll want to make sure the opening is big enough for your largest pet, and obviously rated for their weight too.


5. Consider Dog Door Installation Location

There are several locations you have the option of installing your dog and pet door at:

  • Timber Door
  • Steel Door (including garage doors)
  • Aluminium and Glass Sliding Door
  • Mesh Fly Screen Door
  • Wall – usually brick
  • Aluminium Sliding Window (e.g. the Ideal Pet Products Aluminum Sash Window Pet Door)
  • Vinyl Door

Follow the manufacturer instructions for installation, which may or may not involve cutting into an existing door or wall.

If the door or wall requires cutting, you usually have to call in a professional installer.


6. Dog Door Features To Consider

  • Dog Door Flap – Is is tinted or clear? Are there enough holes in the top of the flap to allow flap adjustment? Is there a magnetic lower strip on the flap to secure the flap to the dog door frame? Can you buy replacement flaps for that model of pet door? Is there a double door flap  or triple door flap to create an ‘air-lock’ in the middle of the dog door?
  • Access and Locking/Sealing Options – Does the door come with just the flap? Is there a sliding locking or closing panel inside the frame to manually lock the opening off and stop weather, overdrafts, debris, human intruders and insects/bugs? Is the opening electronic or operated by a SmartKey allowing remote closing and opening?
  • Dog Door Frame – is the dog door frame aluminium or plastic? If plastic, is it a thermoplastic type frame which is better for retaining heat or the cool? If your dog is a chewer, do you want a thicker frame?
  • Dog Door Colors – Are there a range of colors such as white, satin, bronze etc. to fit in with your decor? Is the frame paintable to get an EXACT match with your door?
  • Dog Door Glass – for full height dog doors for sliding glass doors, is the glass tempered or tinted?
  • Weather Seals – for aluminium and plastic dog door frames, are there weather strips around the outside of the frame for insulation?
  • Other Weather Proofing – are there any internal weather proofing flaps like on the 3 flap dog doors? Is there an air lock between the external flap/door and the inside environment? Consider the climate you live in (is it hot, cold or moderate where you live?) to get an idea of the level of weatherproofing you require.
  • Dog Door Layout – for full length dog doors, they come with different layouts and heights of the glass panels and the dog door.
  • Dog Door Bottom Lip – the lip is the bottom of the dog door frame. Some models have a higher lip that sits above the ground to discourage random smaller animals like rodents for example from entering the house.
  • Electronic Dog Doors – specifically with electronic dog and pet doors, look out for the following:

– Programmable setting with option for auto lock and release at different times of the day

– How is the dog door powered or driven? Battery or motor driven?

– LED frame indicators

– Option to increase or increase sensitivity of microchip when your pet is different ranges away

– Does the door work with new microchip collars to trigger the door (sometimes known as a smart key), or can it work with existing microchips?

– Option to program the door for multiple pets’ microships/smartkeys (if you have more than one pet)

– How much are extra microchips/smart keys, and batteries for the smartkeys? How long do the batteries last (usually a year)?

– Are the collars/sensors/microchip collars water proof and durable?


7. Installing a Dog Door – How-To & Other Tips

The average door mounted or track mounted dog door takes around 20 minutes to install by yourself.

Different dog doors will be slightly different to install, and each installation varies in difficulty of installation, and price of installation. 

But, there are four main installation types


  • Install in a door track

Door track mounted dog doors are the easiest to install and least expensive as there are no holes to cut. You just fit the door to the track and screw/fasten it in.


  • Install in a regular door/storm door

Regular doors are somewhere in the middle – you get given a cutout template for your door, and then you install the dog door yourself.

All you generally need to install regular door mounted dog doors is a power cutting tool like a jigsaw, a drill and a screwdriver.


  • Install in a wall

Installing in walls and glass panels/windows can be expensive as you may need to call a carpenter or glazier in to complete the job if it’s not straightforward.

There may be cutting or brick, removal of glass and other specialised activities that a regular person might not have the expertise or tools for.

Get a quote before you buy the pet door so you get a better idea of overall cost.


  • Install in glass window

Refer above


Make sure not to void the warranty of any dog door or pet door that get’s installed around your house. Follow the installation instructions of the manufacturer carefully.


8. Train Your Dog To Use The Dog Door

Not all dogs are comfortable with using dog and pet doors straight away (or the associated sensor collars and microchip devices).

You may need to do some basic positive reinforcement and praise/treat training to encourage your dog to use the door.
