Dog Doors for a Labrador Retriever
The UK's favourite breed — needs a large or XL dog flap. A typical Labrador Retriever weighs 25–40 kg. Deep chest and broad shoulders — head height matters as much as width.

Large to extra-large dog door, 314 × 390 mm and upwards.
How to measure your Labrador Retriever
- 1Measure your dog's shoulder height from the floor — the opening needs to be at least that tall.
- 2Measure the widest point, usually the chest or hips, and add 50 mm.
- 3Watch how your dog goes through a normal doorway: if they duck, the opening needs to be taller.
- 4Measure the chest clearance from the floor so the step-over is easy, not a jump.
Where we fit it: Head height drives the fit for big dogs, not weight. We often end up fitting into a new toughened glass panel or a side panel, simply because a standard door doesn't have the flat area needed.

Microchip compatibility for a Labrador Retriever
UK dogs must be microchipped by law, and those chips are standard 15-digit FDX-B — exactly what the microchip pet doors we fit read. Larger dog doors are usually manual 4-way lock; chip-controlled access is available up to the SureFlap Microchip Pet Door size.
Labrador Retriever microchip tip
Labradors are too big for a chip-reading pet door, so their flap is a manual 4-way lock. The chip stays a legal requirement, not a door key.

Getting a Labrador Retriever used to the dog door
Tape the flap open, call your dog through from the other side, then lower it gradually over a few days. Never push them through — one bad experience takes weeks to undo.
Fitting note: Deep chest and broad shoulders — head height matters as much as width.
