Dog Doors for a French Bulldog
Compact and chunky — a medium dog flap with low step-over. A typical French Bulldog weighs 8–14 kg. Short legs need a low step-over, so we fit the flap low in the door.

Small to medium dog door, roughly 245 × 290 mm.
How to measure your French Bulldog
- 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: We aim for a step-over of about 100–140 mm. Anything higher and short-legged dogs start scrambling, which wears the flap seal out quickly.

Microchip compatibility for a French Bulldog
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.
French Bulldog microchip tip
Frenchies often fit the microchip pet door — chip-controlled access with a low step-over is the ideal combination.

Getting a French Bulldog used to the dog door
Frenchies can get stuck if the step-over is high. Check they walk through flat-footed, not scrambling.
Fitting note: Short legs need a low step-over, so we fit the flap low in the door.
