French Bulldog vs. Boston Terrier: Which compact companion wins?

Ask ten people to choose between these two little charmers and half will pick the one with the funnier face and Tik-Tok worthy antics.

Fair enough. But when looking at pets and comparing the French Bulldog vs Boston Terrier, it is really a question about health and breathing issues, energy, costs and what kind of daily life you can honestly offer.

Key takeaways

• A French Bulldog is often calmer yet chunkier, but health risks are a big part of the decision.

• A Boston Terrier is usually more lively, lean and playful, though not free from their own health worries.

• Both are considered flat-faced dogs, so hot days, hard exercise and noisy breathing need proper attention.

• The best choice is not the cutest puppy. It is the dog with the healthiest shape and the right fit for your home.

• Before choosing either breed, speak to a vet, check breeder paperwork and get a quote for cover while reading the small print on any policy.
  

If you want a small, affectionate sofa mate, a Frenchie may suit you perfectly. If you want a slightly bouncier little clown who enjoys games and interaction, the Boston may be a better match.

That is the simple version.

The better version is this: choose the dog who can breathe well, move well and cope with your routine. Not the dog that looks best on Instagram in a knitted jumper.

The big issue with this type of breed is all due to the face shape.

Both breeds are brachycephalic, which means they have a shortened skull and flatter face. That can affect breathing, temperature control and even sleep.

The PDSA explains that BOAS, or Brachycephalic Obstructive Airway Syndrome, can affect flat-faced breeds and may cause noisy breathing, exercise intolerance and distress. You can read their guidance here: PDSA advice on BOAS in flat-faced dogs.

A short muzzle might look sweet, but it can make normal dog stuff harder.

Dogs such as these may have issues with:

• Sniffing

• Playing

• Cooling down

• Sleeping without snorting like a tiny broken accordion

Noisy breathing should not be treated as “just how the breed is”. The Blue Cross has also warned owners to take snoring, snorting and breathing effort seriously in flat-faced breeds: Blue Cross advice on brachycephalic dogs.

What our own expert says:

“Normal breathing should be noiseless and without any effort at rest. Noisy breathing in brachycephalic dogs is not normal and is an indicator that there is obstruction to airflow.

If you have ever had a cold and struggled to breathe you know this is not a nice feeling and will understand why this is a major welfare issue. If your brachy dog has respiratory noise at rest, snores a lot, struggles to exercise you must seek veterinary attention.

Also consider not buying brachycephalic breeds or at least get one from parents with longer noses and no signs of BOAS themselves.” - Aimee Warner, DVM, resident veterinarian at Waggel

Besides the breathing issues, a French Bulldog's health problems can include spinal issues, allergies, ear infections, they also have skin folds that can become sore, as well as eye problems linked to their head shape.

The Royal Veterinary College has published UK research showing French Bulldogs have higher odds of several disorders compared with other dogs, including narrowed nostrils and as mentioned, the brachycephalic airway disease: RVC research on French Bulldog health.

Common Boston Terrier health problems can also include the same breathing issues, corneal ulcers, cataracts, allergies and patella luxation, where the kneecap slips out of place.

To add a little extra context to this breed comparison, we looked at Waggel claims data across insured dogs to see how French Bulldogs and Boston Terriers compare in the real world.

This should not be treated as a prediction for any individual dog. Every pet is different. But it does give a useful picture of the types of claims we tend to see across each breed.

Do French Bulldogs and Boston Terriers claim more often?

French Bulldogs tend to claim slightly more often than the average dog.

Across our dataset, French Bulldogs averaged around 2.5 to 2.6 claims per insured pet, which was roughly 10% higher than the overall average. Among breeds with a meaningful claims sample, they sat within the higher third for claim frequency.

Boston Terriers were much closer to the overall average.

In our data, Boston Terriers averaged around 2.3 to 2.4 claims per insured pet, putting them close to the midpoint compared with other breeds.

So, while both breeds can need veterinary care, French Bulldogs appeared a little more claim-heavy overall, while Boston Terriers tracked much closer to the average.

For context, both breeds claimed more often than some other popular breeds such as Spaniels, but less often than some higher-claiming breeds such as German Shepherds and Staffordshire Bull Terriers.

How do claim costs compare?

The cost picture was different for each breed.

French Bulldog claims were generally more expensive than average. In Waggel’s data, the average invoiced claim cost for French Bulldogs was just over £500, around 10% higher than the overall average across breeds.

Boston Terrier claims were lower than average. Their typical invoiced claim cost sat in the low-to-mid £400s, around 10% below the overall average.

That does not mean Boston Terriers are “cheap” dogs to insure or treat. It simply means that, in this claims sample, French Bulldog claims tended to be more expensive on average.

It is also worth remembering that a single serious claim can cost far more than the average. Airway surgery, eye treatment, spinal investigations and joint problems can all become expensive quickly.

What conditions appeared most often?

The conditions seen in Waggel claims data also matched many of the health concerns vets often discuss with these breeds.

Boston Terrier claims

Boston Terrier claims were often linked to eyes, allergies and joint issues.

The most common claim areas included:

• Corneal ulcers and other eye-related problems

• Allergies and skin irritation

• Luxating patella

• Tumours or lumps requiring investigation

• Coat or hair-loss issues such as alopecia

• Occasional claims for infection, liver problems and vomiting
  

In this sample, luxating patella stood out as one of the more expensive recurring claim types for Boston Terriers, with some claims costing well over £1,000.

That matters because Boston Terriers are lively little dogs. If a kneecap issue affects movement, it can have a real impact on comfort, exercise and daily life.

French Bulldog claims

French Bulldog claims were more heavily weighted towards skin, allergy, neurological and eye-related issues.

The most common claim areas included:

• Allergies

• Skin allergies and irritation

• Seizures

• Tumours or lumps requiring investigation

• Eye ulcers and corneal ulcers

• Spinal pain

• Ear and skin infections

Allergy and skin-related claims made up a noticeable share of French Bulldog claims in our data. This fits with what many Frenchie owners already know: itchy skin, sore ears and irritated folds can become a repeat problem rather than a one-off vet visit.

Spinal pain was one of the more expensive recurring claim areas, with some claims reaching well over £1,000. Eye ulcer and corneal ulcer claims were also common enough to be worth flagging, especially because flat-faced breeds can be more prone to eye injuries due to their head shape.

What should owners take from this?

The main point is not that one breed is “bad” and the other is “safe”.

It is that French Bulldogs and Boston Terriers carry different risk patterns.

French Bulldogs, in Waggel’s claims data, appeared slightly more likely to claim and a little more expensive to treat on average. Boston Terriers sat closer to the overall average for claim frequency and below average for claim cost, but still showed clear patterns around eyes, allergies and kneecap issues.

For owners, the practical takeaway is simple.

Choose the healthiest individual dog you can. Keep them slim. Watch their breathing, eyes, skin and movement. Do not ignore noisy breathing, repeated scratching, sore eyes or limping.

And before you bring either breed home, read your insurance policy carefully so you understand what is covered, what is excluded and how pre-existing conditions are treated.

Which is better with children?

Both can be a lovely family dog when raised well.

French Bulldogs are often affectionate and people-focused. Boston Terriers can be bright, silly and full of beans.

Either can live happily with children, but only if the children are taught how to behave around dogs too.

• That means no climbing on them.

• No grabbing faces.

• No waking them up for cuddles.

• No “he likes it” when the dog clearly does not.

This is where temperament matters more than breed labels. A calm, well-bred Boston may be easier than a poorly socialised Frenchie. A steady Frenchie may be easier than a frantic Boston. Meet the individual dog, not the stereotype.

Which is better for flats?

Both can work as an apartment dog, and both are popular with people in smaller homes.

For flat living, a Frenchie may be quieter and more settled indoors. A Boston may need more play, puzzle toys and little training games to stop boredom creeping in.

Neither should be left alone all day. Both can struggle with separation anxiety if they do not learn to relax by themselves in a gradual, kind way.

A small home is fine. A lonely life is not.

These are small dogs, not ornaments.

They still have exercise needs, but exercise needs to be sensible. Our own breed guides suggest around 15–30 minutes per day for French Bulldogs and 30–60 minutes per day for Boston Terriers. Think short walks, sniffy routes, gentle play and brain games. Not long runs in warm weather.

Their heat tolerance is often poor compared with longer-nosed breeds. The RVC has warned that brachycephalic dogs are at higher risk of heat-related illness, especially in warm weather or after exertion: RVC heatstroke risk research.

With that being the case, watch them closely for overheating. Heavy panting, drooling, wobbling, panic or collapse are not “wait and see” signs.

Keeping your dog at a healthy weight also matters. Extra weight can make breathing, joints and heat stress worse.

Boston Terriers are often keen little learners. French Bulldogs can learn well too, although some like to consider your request, file it internally, then ignore it with great confidence.

Use kind training methods.

Short sessions work best. Food rewards help. Praise helps. Being consistent helps even more.

Early socialisation is important for both breeds. Your puppy should gently meet normal life, including visitors, traffic, handling, other dogs and the vet.

Use positive reinforcement, not shouting or punishment. Good dog behaviour is built through trust, repetition and making the right choice easy.

As we have been saying, a good puppy is not just the one with the prettiest photo.

When it comes to the costs for each breed, it can vary a lot, however our breed guides list French Bulldog puppies in the UK at around £1,000 to £3,000 or more, and Boston Terrier puppies at around £1,100 to £2,000.

Remember, expensive does not always mean healthy. Look for a responsible breeder who shows health evidence, lets you meet the mother, answers awkward questions and does not market “rare” colours as if buying a dog is the same as buying trainers.

The Kennel Club has helpful advice on buying a puppy and checking health information: Kennel Club puppy buying advice.

A rescue dog can also be a brilliant choice, especially if you are open to an adult with known needs.

You may also come across the Frenchton, which is a French Bulldog and Boston Terrier cross. A crossbreed can still inherit airway, eye, skin or joint issues from either side, so do not assume “mixed” automatically means healthy.

This bit is not glamorous, but it matters.

Both breeds can come with higher vet bills than some other small dog breeds, especially if airway surgery, eye treatment, allergy care or joint treatment is needed.

When you work out your dog ownership costs, be sure to include food, vaccinations, flea and worm treatment, dental care, routine checks, emergency savings and also pet insurance.

Read the policy documents before you buy cover. A pre-existing condition is usually handled differently from a new illness, so timing matters.

If your dog already has noisy breathing, sore eyes, skin infections or a limp, ask your vet what that may mean before assuming a policy will cover it.

For routine care, this Waggel guide on how often you should take your dog to the vet is worth reading.

Here is the honest answer to which breed is better.

The best dog is the one whose body can cope with normal life.

Choose the dog who breathes quietly at rest, has open nostrils, bright eyes, good movement and a stable personality. Choose the breeder or rescue who cares more about welfare than quick sales.

If you are asking which dog should I choose, start with your routine.

Choose a French Bulldog if...

You want a lower-energy companion dog, you are home a lot, you can manage possible health costs and you are willing to put welfare before looks.

Choose a Boston Terrier if...

You want a livelier compact companion, enjoy play and simple training, and understand that flat-faced breed care still applies.

Choose neither if...

You want a jogging partner, need a dog to cope alone for long days, live in a very hot home or cannot budget for health care.
