French bulldog: temperament, health, care, and cost

The French bulldog has become one of the most popular dogs in the world. In 2022, Frenchies knocked the Labrador out of the top spot in the American Kennel Club (AKC) rankings for the first time in more than three decades. It’s easy to see why: they’re small, funny, affectionate, quiet, and happy in an apartment.

But that flat face comes at a cost many families only learn about later. Their anatomy makes them prone to brachycephalic obstructive airway syndrome (BOAS), which makes breathing harder, turns hot weather into a genuine danger, and limits how much exercise they can handle. This guide explains plainly what the breed is like, how to spot breathing problems, how to keep a Frenchie safe in the heat, and how to tell a responsible breeder from one who isn’t.

French bulldog quick facts

Where the French bulldog comes from

The story starts in England. In the mid-1800s, many lace workers from Nottingham moved to France and brought their small bulldogs with them. In Paris, those dogs were crossed with local dogs and became favorites with shopkeepers, carriage drivers, and artists.

The first French breed club was founded in 1880. Toward the end of the century, American fanciers championed the breed’s signature bat ears over the “rose” ears of the English bulldog, and the AKC recognized the breed in 1898. Later selection for ever-flatter faces is the root of many of the breed’s health problems today.

French bulldog temperament

The Frenchie is a companion dog through and through: they want to be with you, follow you around the house, and sleep nearby. They’re cheerful, clownish, and usually friendly with guests.

• They don’t bark much, but they “talk” with grumbles, snorts, and a whole range of funny noises.
• They’re stubborn: quick learners when something’s in it for them, so food and play are the keys to training.
• They need company: long stretches alone can lead to separation anxiety.
• They’re adaptable: a city apartment or a house with a yard both work, as long as they’re with their people.

With kids, other pets, and training

Most Frenchies get along with kids and with other dogs and cats when socialized early, which is why they show up on many lists of the best dog breeds for families with kids. Keep in mind that they can’t handle long, intense play, shouldn’t jump out of arms or off the couch because of their backs, and kids need to learn to lift them supporting both the chest and the hind end.

Always train with positive reinforcement, in 5-minute sessions with tiny treats. And use a harness instead of a collar: any pressure on the neck makes breathing harder.

Brachycephalic syndrome (BOAS): what to know before you get one

Brachycephalic obstructive airway syndrome, or BOAS, is the breed’s biggest health problem. A large 2021 VetCompass study from the Royal Veterinary College in the UK found that French bulldogs had a higher risk than other dogs for nearly half of the common disorders it looked at, with especially high risks of narrow nostrils and BOAS.

What it is and why it happens

As breeders selected for shorter and shorter muzzles, the bones of the skull got shorter, but the soft tissues didn’t shrink to match. The result is a crowded airway:

• Stenotic nares: nostrils so narrow that air barely gets in.
• An elongated, thickened soft palate that blocks the entrance to the larynx.
• Abnormal nasal turbinates that obstruct the inside of the nose.
• Everted laryngeal saccules and laryngeal collapse, secondary changes that develop over time from the constant effort of breathing.

Because the dog has to work so hard to breathe, the problem gets worse with age if left untreated.

Symptoms: when breathing isn’t normal

Many owners assume snoring and snorting are “just how the breed is.” They aren’t: they’re signs that air isn’t moving freely.

If your dog seems to pant more than they should, our guide to why your dog is panting so much helps you tell normal from worrying.

Diagnosis and treatment

Your vet will assess breathing at rest and after light exercise. The University of Cambridge, working with the UK Kennel Club, developed a respiratory function grading scheme that scores each dog from grade 0 (no signs) to grade 3 (severe), based on a 3-minute trot and listening to the airway before and after.

Moderate and severe cases can improve a lot with surgery: widening the nostrils, shortening the soft palate, and removing everted saccules. It works best when done early, before irreversible changes in the larynx set in. Keeping your dog lean also eases symptoms.

Heat and exercise: keeping your Frenchie safe

Dogs shed heat mainly by panting, and a Frenchie with a narrow airway does it poorly. A 2020 VetCompass study ranked the French bulldog among the breeds at highest risk of heatstroke, alongside the English bulldog and the chow chow.

As a guideline, a healthy adult needs 30 to 60 minutes of walking a day, split into 2–3 easy outings, plus play indoors. No running next to a bike, long hikes, or intense fetch sessions. Always adjust to the temperature:

A Frenchie with moderate BOAS or extra weight can struggle even below those temperatures, and high humidity makes everything worse.

Know the signs of heatstroke: very heavy, noisy panting, thick drool, a bright red or bluish tongue, vomiting, stumbling, or collapse. Move your dog to the shade, wet them with cool (not ice-cold) water, offer water, and head to the vet right away. Our guide to heatstroke in dogs covers it in detail.

Daily care and feeding

The short coat is easy: a weekly once-over with a rubber grooming mitt is plenty. The skin and face need more attention.

• Facial folds: clean them 2–3 times a week with damp gauze and dry them thoroughly. Trapped moisture causes fold dermatitis and infections.
• Tail pocket: many Frenchies have a small pocket by the tail that collects dirt; check and dry it.
• Eyes: they’re prominent and easily injured. If your dog squints, tears up, or paws at an eye, see the vet that same day.
• Ears: check them weekly; ear infections are common in the breed.
• Nails: trim every 3–4 weeks if they don’t wear down.

As for food, an adult Frenchie weighing 20–28 lb (9–13 kg) typically needs roughly 500–750 calories a day, depending on activity and whether they’re spayed or neutered. Fine-tune portions with our guide on how much to feed your dog. Every extra pound makes breathing harder and loads the spine, so measure meals, split food into 2 meals, and use a slow feeder if your dog gulps.

Other common French bulldog health problems

Beyond BOAS, the breed is prone to several other problems worth knowing about before you bring one home:

To protect their back, use ramps or steps for the couch and bed and avoid repeated jumps from height. Pet insurance with solid surgical coverage is especially worth considering for this breed. None of this replaces an exam by your own vet.

Is a French bulldog the right dog for you?

Read our guide on how to choose the right dog and be honest about whether a Frenchie fits your life.

A Frenchie is a good fit if you:

• Live in an apartment and want a mellow dog with modest exercise needs.
• Spend a lot of time at home and want a very affectionate companion.
• Can afford high vet bills, including possible surgery.

Look at other breeds if you:

• Want a running, hiking, or summer beach buddy.
• Live somewhere very hot without air conditioning.
• Have a tight budget for vet care.

How to choose a responsible French bulldog breeder

With this breed, the breeder can make the difference between a dog who breathes normally and one who struggles for air every day. Ask for, and verify:

1. A breathing assessment for both parents, ideally graded 0 or 1. A grade 3 dog shouldn’t be bred.
2. Parents who breathe quietly at rest and after moving around, with visibly open nostrils and a muzzle that isn’t extremely short.
3. Eye, heart, and kneecap exams, spinal X-rays if possible, and the DNA test for hereditary cataracts (HSF4).
4. Only standard colors. Merle, blue, and “lilac” are sold as exclusive, but they’re disqualified by the AKC and the FCI and are linked to problems: breeding two merles can cause deafness and blindness, and dilute colors are linked to hair loss and skin issues.
5. Meeting the mother, puppies at least 8 weeks old, a vet record, and a written contract.

How much does a French bulldog cost, and what about adoption?

In the US, a Frenchie puppy from a breeder who health-tests the parents commonly costs around $2,500–$5,000, and sometimes more. Prices vary by region, bloodline, and testing, and they’re high partly because artificial insemination and C-sections are routine in the breed. A high price doesn’t guarantee a healthy dog: “rare” colors often sell for more with zero health benefit. Avoid pet stores and online sellers who ship puppies sight unseen.

Budget for vet care, too: airway, spine, or eye surgery can run into the thousands of dollars, depending on the clinic and what needs fixing.

More and more Frenchies are landing in shelters and breed-specific rescues, often because their families couldn’t keep up with their medical needs. Adopting an adult lets you know their breathing status and personality up front, and adoption fees are usually a few hundred dollars, often including vaccines, a microchip, and spay or neuter surgery. Our guide to adopting a dog walks you through the process.

Frequently asked questions

Is it normal for my French bulldog to snore?

No. As common as it is, loud snoring, snorting at rest, or noisy breathing means air isn’t moving well through the nose, palate, or larynx. It doesn’t always call for surgery, but it does call for a vet assessment, because BOAS gets worse over time. The sooner it’s evaluated, the more treatment options you have and the better the results.

Can brachycephalic syndrome be fixed with surgery?

It can be greatly improved. Surgery widens the nostrils, shortens the soft palate, and removes everted laryngeal saccules if needed. Most dogs breathe much better afterward, though surgery won’t give them the airway of a long-nosed dog. Results are best in young, lean dogs. Your vet will weigh the anesthesia risk, which is somewhat higher in flat-faced breeds.

Can a French bulldog fly on a plane?

It’s tricky. Many airlines won’t accept brachycephalic breeds as checked baggage or cargo because of the risk of breathing problems and heatstroke. In the cabin, your dog has to fit in a carrier under the seat, which is a tight squeeze for many adult Frenchies. Check the airline’s policy well ahead and talk to your vet; a climate-controlled car trip is usually the safer choice.

How long can a French bulldog be left alone?

A well-adjusted adult can handle 4–5 hours alone if the house stays cool, there’s water available, and they’ve had a potty break first. Frenchies are very attached to their people, so long absences every day often lead to anxiety. In summer, never leave them alone in a home that heats up without air conditioning.

Why are French bulldogs so expensive?

Because breeding them well is expensive: many females need artificial insemination and a C-section, litters are small, and health testing the parents costs money. High demand pushes prices up too. But a high price doesn’t guarantee a healthy dog. What matters is the breathing and health screening on both parents, not the color or size.
