Dog Doors for a West Highland Terrier
Westies love outdoor access — standard dog flap size is ideal. A typical West Highland Terrier weighs 3–10 kg. Sturdy little dogs — a microchip pet door works nicely.

A large cat flap or small dog door (around 214 × 256 mm).
How to measure your West Highland Terrier
- 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: Small dogs need a low step-over, so we fit the flap as low in the door panel as the frame allows — typically 80–120 mm above the floor.

Microchip compatibility for a West Highland Terrier
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.
West Highland Terrier microchip tip
Westies are a good fit for the microchip pet door — chip entry keeps the household to your dog only.

Getting a West Highland Terrier 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: Sturdy little dogs — a microchip pet door works nicely.
