Dog Doors for a Whippet
Tall and slim — may need a taller flap opening. A typical Whippet weighs 12–22 kg. Narrow but tall: height of the opening is the limiting factor.

Medium dog door, roughly 245 × 290 mm.
How to measure your Whippet
- 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: The step-over usually sits around 150–200 mm. We check the panel has enough depth above the opening for the flap frame before we cut.

Microchip compatibility for a Whippet
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.
Whippet microchip tip
Whippets are narrow but tall, so height rules them out of a microchip pet door — a manual medium door it is.

Getting a Whippet 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: Narrow but tall: height of the opening is the limiting factor.
