What size crate does a French bulldog need?

French bulldogs are brachycephalic: their skulls are compressed front-to-back, so the same tissue that a Labrador has laid out in a long muzzle is stuffed into a Frenchie's short one. Narrow nostrils, an elongated soft palate, and a small windpipe all mean this dog cannot cool itself efficiently. Panting — the primary way dogs shed heat — barely works. A room that feels pleasantly warm to you can push a crated Frenchie into genuine respiratory distress inside 15 minutes.

Practical rule: always use an open wire crate at home, never a solid plastic airline kennel except for actual travel. Position it away from radiators, sunny windows, and top floors that trap heat. In summer, run AC or a floor fan aimed near — not directly at — the crate. Never crate a Frenchie in a parked car, even with windows cracked, even for five minutes.

If your Frenchie snores loudly, gags after mild excitement, or has gums that look bluish or grey after crate rest, that's a BOAS (brachycephalic obstructive airway syndrome) conversation with your vet. A bigger crate will not fix an airway that needs surgical widening.

8–12 week Frenchie pups are 6–10 lb and physically fit an 18" crate, but buy the 22" adult crate with a divider — you'll only shrink usable space by a few inches, and you won't be re-buying anything at six months. Set the divider tight to discourage in-crate potty accidents.

Between 4 and 6 months Frenchies are usually 14–20 lb and enter a serious chewing phase. Skip plush beds and fleece blankets — many Frenchies shred them and swallow strips. A bare crate pan with a rubber-backed kennel mat is safer until 12–18 months.

By 9–12 months you're at adult size (16–28 lb). Remove the divider. Don't size up: Frenchies are compact rather than tall, and extra length just becomes wasted floor.
