Crates for a French Bulldog: size, type, heat, and the weeks after a disc

A crate does three jobs in this breed and people buy it for one. It is the puppy's bedroom in the first weeks, it is the restraint the Highway Code asks for in the car, and it is where a French Bulldog spends several weeks if a disc goes, which in this breed it does young. Buy it for the third job and the first two are covered.

Size

The RSPCA's rule is the only one that matters: "make sure your dog has enough room to sit and stand up at full height, turn around easily and lie down in a natural position." An adult of this breed is about 30 cm at the shoulder, 11 to 12.5 kg, and roughly 60 to 70 cm from nose to the base of the tail. A 24-inch crate, 61 cm long, does not let it lie stretched. A 30-inch crate, 77 to 78 cm long and 56 to 61 high, does, with room to spare, and it is the size Omlet's own guide puts the breed's weight band on: "Breeds up to 20kg". A 36-inch crate is fine and is the one the same guide names "Bulldogs" under; it is also 92 cm of floor. A puppy goes in the adult crate with the divider in, not in a small crate to grow out of.

Wire, and why not fabric or plastic

A French Bulldog sheds heat by panting through an airway that does not work well, and the UK heat-illness data found flat-faced dogs had greater odds of every kind of heat illness, with the environmental kind, a dog that cannot get away from a warm room, the one that older dogs and dogs with breathing trouble were most prone to. A fabric crate is a tent and a plastic transport box is a cupboard; both trap the air the dog is trying to lose. Wire is open on four sides. Put it where the sun does not reach in the afternoon, never in a conservatory, and treat a blanket over the top as something for winter. The summer kit page has the rest.

Time

The RSPCA describes a crate as "a safe, secure area that a dog can go into for short periods of time" and gives no number of hours, and neither will we, because none of the UK charity pages we could reach gives one. A crate is where a dog sleeps and where it goes when the front door is open. It is not where it spends a working day, and a puppy under four months cannot hold on for the length of one anyway. The door stays open when someone is home.

Crate rest after a disc

What the evidence says

The IVDD page says strict rest of four to six weeks for a mild case. That figure is common practice, and the honest note is that it is practice rather than a trial result: no UK page with a number could be reached when this page was written. What the trials do show is that conservative management works more often than owners fear. In a prospective study of 72 dogs that could not walk after a thoracolumbar disc extrusion, managed without surgery, 96% of those that could still feel their toes were walking within twelve weeks, with a median of 11 days; the study was in small non-flat-faced dogs, so the number is an encouragement, not a French Bulldog figure. A 2025 study of forty dogs with three other, non-compressive spinal diagnoses found rest made no difference to relapse in the month after discharge, with the authors' own caution about their groups; that is not licence to skip rest after an ordinary disc extrusion, and this page does not read it that way.

What strict means

In the crate except to toilet, on a lead, carried down any step. Water in the crate. Nothing to jump onto when the rest ends, which is where the ramp earns its place. Half of French Bulldogs in a 2026 surgical series had a complication afterwards against one in eight Dachshunds, with regurgitation the breed's own, so a dog recovering at home is watched for bringing food up and for not passing urine, and the vet is rung rather than waited for. The length of rest is the vet's to set. The crate's job is to make the rest possible without a fight, which is why a dog that already sleeps in one recovers more calmly than a dog meeting one for the first time on the worst day of its life.

The car

Rule 57 of the Highway Code: "When in a vehicle make sure dogs or other animals are suitably restrained so they cannot distract you while you are driving or injure you, or themselves, if you stop quickly. A seat belt harness, pet carrier, dog cage or dog guard are ways of restraining animals in cars." A wire crate in the boot meets the rule; whether it protects the dog in a crash is a separate question that no UK or EU standard answers, and the travel page deals with it. In summer the crate in the boot is also the hottest place in the car.

Crate furniture

A wooden crate that passes as a side table is the same wire door and tray inside a box. Omlet's Fido Studio comes in two sizes: the 24, with an internal length of 61 cm, which is too short for an adult of this breed to lie stretched, and the 36, internal 88 cm, which is ample; there is no 30. Wooden panels on two sides also close off two sides of airflow, which is the thing the last section was about. A wire crate under a cloth on a warm day is the same object. If the furniture version is the one the house will accept, buy the 36 and site it in the coolest room.

What we did not read

The Dogs Trust, Blue Cross, Kennel Club and PDSA crate-training pages all refused automated reads, so the RSPCA's is the only charity wording here. No study of crate stress in flat-faced dogs exists to read. The Omlet furniture prices were not on the page fetched. The crate-rest duration is practice, not a trial, and the page says so above.
