Boston Terrier vs. French Bulldog: A Comparison Guide

Boston Terriers and French Bulldogs may look similar at first glance, with their compact bodies, short snouts, and signature bat-like ears.

Boston Terrier vs. French Bulldog: breed origins and history

The Boston Terrier and the French Bulldog (aka Frenchies) look similar because both trace back to a common ancestor: the Bulldog. But their histories differ. 

French Bulldogs were developed in France in the 19th century by English immigrants who wanted a smaller, more portable companion than the Bulldogs they brought with them. As Frenchies gained popularity abroad, American travelers took notice and eventually brought the breed back to the United States. Today, Frenchies hold the title of America’s most popular dog breed.

In contrast, the Boston Terrier was developed in Boston in the late 1800s. The first Boston Terrier was a cross between an English Bulldog and the White English Terrier (which no longer exists). Although early breeders hoped to create a more compact fighting dog, they ultimately produced a gentle, well-mannered companion. Nicknamed the “American Gentleman,” the Boston Terrier earned this title thanks to their tuxedo-like coat pattern and polite, affectionate nature.

Boston Terrier vs. French Bulldog: physical differences

French Bulldogs and Boston Terriers share similar physical features. But they’re easy to tell apart once you know what to look for.

• Ears: Boston Terriers have pointed, upright ears, while Frenchies have larger, more rounded “bat ears.”

• Head shape: Bostons have rounder skulls, whereas French Bulldogs have broader, square-shaped heads.

• Body: Boston Terriers are lighter and leaner, typically weighing less than 25 pounds. Frenchies have a thicker, heavier build and can weigh up to 28 pounds.

• Height: They are similar in height, though Frenchies may be slightly taller.

• Coat colors: Both breeds can be black and white, but Boston Terriers usually have clean, tuxedo-like markings. Bostons can also come in brindle and seal, and typically have a white stripe between the eyes — a feature that’s not consistently seen in Frenchies. Frenchies come in a wider range of colors, such as brindle, fawn, cream, and white, and their patterns can be more varied.

Boston Terrier vs. French Bulldog: temperament and personality differences

Boston Terriers are playful, affectionate, and eager to interact with their people. Bred as true companion dogs, they typically get along well with people of all ages and are often welcoming toward strangers. They enjoy playtime and activities like agility, but they also have a mellow side and happily unwind with their families.

French Bulldogs share that people-focused, friendly nature, but they bring their own twist to it. They’re known for their goofy and occasionally sassy personalities, and can be a bit stubborn and independent at times. They also generally prefer a more relaxed, laid-back lifestyle than Boston Terriers.

Boston Terrier vs. French Bulldog: health

Boston Terriers typically live 11 to 13 years, while French Bulldogs have a slightly shorter average lifespan of 10 to 12 years.

Both breeds are brachycephalic, meaning they have short snouts and flat faces that can cause breathing difficulties. As such, both breeds are at risk of heatstroke and should not be intensely exercised, especially in hot or humid conditions. 

Boston Terriers have less-flat faces than French Bulldogs, which often means fewer breathing issues and better physical agility.

French Bulldog health issues 

In addition to breathing problems, French Bulldogs are also at increased risk for:

• Patellar luxation

• Hip and elbow dysplasia

• Spinal problems

• Heart disease

• Skin fold infections (due to deep skin folds and wrinkles)

• Eye problems (cherry eye, cataracts, corneal dystrophy, etc.)

• Weight gain and obesity

• Skin and food allergies

• Dental disease

Additionally, because of their bulky, front-heavy structure, Frenchies cannot swim and should never be left unattended near a tub, pool, or body of water.

Boston Terrier health issues 

In addition to breathing problems, Boston Terriers are prone to the following: 

• Patellar luxation

• Deafness

• Spinal problems 

• Eye problems (glaucoma, ulcers, cataracts)

• Dental disease

• Skin and food allergies

• Cushing’s disease

Should you adopt a Boston Terrier or a French Bulldog?

Choosing between a Boston Terrier and a French Bulldog comes down to what you’re looking for in a companion and your ability to provide the care they need. 

Here are a few key points to keep in mind when deciding which breed is the best match for you.

​Living situation and energy level

​Both breeds adapt well to living in apartments or houses. If you want a dog who’s happy with a calm, slower-paced lifestyle, a Frenchie might be the better fit. If you prefer a dog with a bit more pep and agility, a Boston Terrier may be the right choice.​

Health considerations​

Although both breeds are brachycephalic, French Bulldogs tend to experience more serious breathing problems and a wider range of genetic health issues than Boston Terriers. Prospective adopters may need to prepare for higher veterinary care costs for French Bulldogs.

Training and temperament

​Both Bostons and Frenchies are typically eager to please and quick to learn, making training relatively easy. That said, French Bulldogs can have a stubborn streak, which can make training a bit more challenging. Both breeds learn best with positive reinforcement training and short sessions.

Grooming and care

Both breeds have short, low-shedding coats, but Frenchies require more skin-fold cleaning and may need extra care to prevent infections. Bostons are generally lower-maintenance in this area.

Should I Adopt From a Breed Rescue?

Short answer: Yes. Here are the many reasons why.

Where to adopt a Boston Terrier or French Bulldog

​If you’re ready to welcome a Boston Terrier or French Bulldog into your home, adoption is a wonderful way to give a dog a second chance and reduce the burden on overcrowded shelters and rescues. Here’s where to look for your new family member.

Local animal shelters

​Your local shelter is always a great place to start. Boston Terriers, French Bulldogs, and their mixes sometimes end up in municipal shelters or humane societies through no fault of their own. Often, this happens because of changes in their previous family’s circumstances, medical needs, or housing.

Breed-specific rescues

Breed-specific rescues focus solely on a specific breed, such as Boston Terriers or French Bulldogs, or a group of similar breeds. These rescues often take in surrendered or at-risk shelter dogs. They rely on foster homes, which means dogs are living in a home setting where their behavior, personality, and needs can be better understood before adoption.

All-breed rescue groups

​Many all-breed rescue organizations take in small companion dogs, including Boston Terriers, French Bulldogs, and their mixes.

Pet adoption websites

​Online adoption platforms, such as Adopt a Pet, make it easy to search for adoptable Boston Terriers or French Bulldogs (and their mixes) from shelters, rescues, and private rehoming listings nationwide. You can filter by age, location, activity level, and compatibility with children or other dogs, making it easier to find a dog who fits your lifestyle.

Commonly asked questions

Are Bostons healthier than Frenchies?

Both breeds are brachycephalic (flat-faced), but French Bulldogs generally face a higher risk of breathing problems and other genetic health issues than Boston Terriers.

Is a Frenchton better than a French Bulldog?

​A Frenchton (a Boston Terrier–French Bulldog mix) may inherit fewer breathing issues and be slightly more active than a purebred Frenchie. However, health and temperament can vary widely from dog to dog. Ask the rescue, shelter, or individual if they can provide information about the specific dog you’re interested in.

Do Boston Terriers bark more than French Bulldogs?

​Boston Terriers and French Bulldogs are both low-barking breeds, though Bostons may be a bit more vocal.
