Sizes

What flap sizes are available? 

Our dog doors for sliding doors come in THREE sizes as outlined below in the picture and table (the small has been discontinued as most customers order the medium even with small pets). The bottom rail (rise) is only 5cm on ALL sizes so easy for pet access even when they are old! 

*NOTE XL BLACK is on back order until July 2024: Order online to put one on back order and we will send it out as soon as we can for you (note XL ONLY comes in black).

How do I select the flap size for my pet? 

Are you aware that many people overestimate the size of the flap they need? Please ensure you check the flap size against the shoulder height and width of your dog as weight is not a good guide due to all the different shapes and sizes of breeds. 

It is best if the shoulder height of your pet is a minimum of 1-2cm shorter than the top of the flap so that they can easily get through the flap without hitting their back.

Please note cats tend to use the small flap unless they are bigger than average- in which case select a medium flap.

DOGS! Most small-medium size dogs prefer the medium flap (same price as the small flap). Only order the small for tiny tiny breeds like Mini Dachs/Poodles or Chihuahuas.

First: Flap Width: Check the width of your pet across the shoulders and then refer to the table below. Testing width: Partly open the sliding door to the flap widths to find which size works best (e.g., 16cm / 22cm / 27cm / 39cm ) :)

Second: Flap Height: Measure your pet from the ground to the top of their shoulders then refer below.

NOTE: The flap height is from the ground to the top of the flap.
