Appearance

Primary Colors
Secondary Colors
Skin Type Domestic dog skin with short, smooth, close-lying coat. Skin can be moderately sensitive; common issues include environmental/food-related dermatitis and skin-fold irritation in individuals with more pronounced facial wrinkles (French Bulldog-leaning).
Distinctive Features
  • Designer crossbreed (French Bulldog and Boston Terrier) within domestic dog taxonomy; not a wild species and not a uniformly standardized kennel-club breed-appearance and health risks vary by lineage.
  • Compact companion build: small-to-medium, sturdy, muscular body; typically shorter-legged and heavier-boned than many other small dogs, though size varies with parentage.
  • Brachycephalic to moderately short muzzle: many have a shortened face (more French Bulldog-like), predisposing to snoring and reduced heat tolerance; others are less brachycephalic (more Boston-like).
  • Head and ears: broad skull, prominent round eyes; ears may be upright 'bat ears' (French influence) or more triangular/terrier-like; ear set can be asymmetrical.
  • Tail: can range from a short/natural bob or screw tail (French influence) to a longer, straighter tail (Boston influence); tail type affects hygiene needs around the tail base.
  • Coat: short, low-shedding to moderate-shedding; easy grooming but benefits from regular brushing to reduce dander and manage seasonal shedding.
  • Common health issues (vary by genetics): brachycephalic obstructive airway syndrome (BOAS), heat stress, eye irritation/corneal injury, allergies/atopic dermatitis, patellar luxation, spinal problems (hemivertebrae/IVDD risk), dental crowding, and obesity strain.
  • Avoid overheating: keep cool, limit hard exercise in heat or humidity. Use a harness, not a neck collar, to protect airways. Give moderate daily exercise with breaks. Keep lean and clean teeth, nails, ears, and facial folds.

Sexual Dimorphism

Sexual dimorphism is generally mild in this companion crossbreed. Males are often slightly larger/heavier with broader heads and thicker necks, while females tend to be a bit smaller and more finely built; individual variation and parent-line influence can outweigh sex differences.

  • Often slightly greater overall mass and chest width
  • Broader head/jaw appearance, thicker neck in some lines
  • Often slightly lighter build and narrower chest
  • May appear more refined through the waist and limbs, though variation is common

Did You Know?

A Frenchton is a crossbreed (French Bulldog × Boston Terrier), so looks and temperament can vary widely even within the same litter.

Many inherit the French Bulldog's "bat ears," the Boston Terrier's tuxedo-like markings, or a mix of both.

Because both parent breeds are brachycephalic (short-muzzled), Frenchtons can be heat- and exercise-sensitive, especially in warm weather.

They're often chosen for apartment living: typically small, sturdy, and more "people-oriented" than prey-driven.

Snoring and noisy breathing are common in lines with shorter muzzles; quiet sleep is not guaranteed.

They tend to bond closely with their households and may prefer being near their person rather than wandering independently.

Frenchtons are part of the modern "designer dog" trend-valued for companionship rather than a historical working role.

Unique Adaptations

  • Companion-focused temperament: selectively bred lineage (both parents) for human proximity and indoor living rather than endurance hunting.
  • Compact, muscular build that fits small homes while still being sturdy for gentle play.
  • Brachycephalic head shape can make breathing less efficient-an important "tradeoff trait" that requires lifestyle adjustments (cooling, pacing exercise).
  • Coat is typically short and low-shedding compared with many dogs, but skin can be sensitive; regular skin-fold and ear care matters depending on anatomy.
  • Hybrid variability: crossing two established breeds may yield a broader range of muzzle length, ear set, and respiratory comfort than either parent alone (not guaranteed).

Interesting Behaviors

  • Velcro-dog tendencies: following their favorite person room to room and seeking lap time.
  • Play bursts ("zoomies") followed by quick settling-often alternating between energetic play and couch naps.
  • Expressive communication: a mix of snorts, grumbles, and body language typical of brachycephalic companion dogs.
  • Social "greeter" behavior: many are friendly with visitors, though some can be selectively wary without early socialization.
  • Toy-driven play and short training sessions work well; long repetitive drills may lead to stubborn "checks out" moments.
  • Sunbathing and heat-seeking indoors-followed by overheating risk outdoors in warm/humid conditions.

Cultural Significance

Frenchtons reflect 21st-century companion-dog culture: intentional crossbreeding for a small, personable pet suited to urban life. Their popularity is tied to the broader "designer dog" movement, social-media visibility, and long-standing affection for their parent breeds-French Bulldogs as iconic city companions and Boston Terriers as the classic "American Gentleman."

Myths & Legends

Name lore: "Frenchton" is a modern portmanteau blending "French (Bulldog)" and "Boston (Terrier)," a naming style that helped fuel designer-dog recognition.

A common French Bulldog origin story says small bulldog-type dogs went with English lace workers to France during the Industrial Revolution, became popular there, and changed into the modern French Bulldog.

Boston Terrier identity story: the breed became known as the "American Gentleman" for its tuxedo-like markings and polite companion reputation-an image that carries into Frenchton expectations.

College mascot anecdote: Boston University's live dog mascot "Rhett" helped cement the Boston Terrier's cultural footprint in the U.S., indirectly boosting familiarity with Boston Terrier mixes.

Parisian companion-dog association: French Bulldogs are frequently depicted in late-19th/early-20th-century urban companion settings (posters, photographs, and anecdotes), contributing to the romantic "city sidekick" narrative that Frenchton owners often echo.

Behavior & Ecology

Social Household pack Group: 2
Activity Diurnal, Cathemeral
Diet Omnivore Meat-forward, highly palatable foods (e.g., poultry or beef-based kibble/wet food); many Frenchtons strongly prefer soft/wet textures due to short muzzles and dental crowding.

Temperament

Affectionate, people-focused companion; typically seeks frequent contact (leaning, lap-sitting)
Playful but often in short bursts; stamina and heat tolerance are usually lower than many other domestic dog types due to brachycephalic traits
Generally friendly and sociable with familiar people; can be reserved with strangers without early, positive exposure
Alert and sometimes vocal at doors/noises; watchdog tendencies vary (often more Boston-terrier-leaning individuals)
Trainability: responsive to positive reinforcement and routine; may show stubbornness and sensitivity to harsh handling
Potential separation-related behaviors (whining, pacing, destructive chewing) if attachment is strong and alone-time training is lacking
Dog-to-dog sociability is often good when well-socialized; some individuals may be pushy in play or intimidated by larger, fast-moving dogs
Breed-related care notes affecting behavior: avoid overheating/overexertion; use harness rather than collar to reduce airway/neck strain; keep sessions short with rest breaks
Common health concerns that influence social/behavioral expression: brachycephalic obstructive airway syndrome (snoring, exercise intolerance), heat stress risk, skin/allergy issues, patellar luxation, eye irritation/cherry eye, dental crowding, and possible spine issues (e.g., IVDD/hemivertebrae-more Frenchie-influenced lines)

Communication

Short to moderate barking Alert/attention-seeking
Whines/whimpers for contact, anxiety, or frustration
Growls/grumbles during play or boundary-setting
Barks that escalate with excitement in high-arousal play
Breed-typical brachycephalic sounds (snorts, snuffles, stertor/snoring) that can accompany excitement or exertion and may signal respiratory strain
Close-contact solicitation Pawing, nudging, leaning, climbing into laps
Facial expressions and gaze alternation Strong human-directed 'checking in'
Body posture: play bows, bouncing, and short sprint 'zoomies' with frequent pauses
Scent investigation and light marking behavior typical of domestic dogs Usually modest in neutered pets
Mouthy play/soft nipping more common in excitable individuals-managed with training and appropriate chew outlets
Stress signals: lip-licking, yawning, turning away, freezing; may be subtle in brachycephalic faces-handlers should watch whole-body cues
Thermoregulatory signaling relevant to the breed: panting escalation, widening stance, seeking cool surfaces-important early indicators to stop activity

Domestication Status

Domesticated

Frenchton (Canis lupus familiaris) is a modern designer cross of the French Bulldog and Boston Terrier, bred in the late 20th–21st century as a small, indoor companion. They are social and playful but can have short muzzles with breathing and heat risks. Care: keep cool, moderate exercise, dental and vet checks.

Danger Level

Low
  • Bites/nips can occur with fear, pain, poor socialization, or rough handling (risk is generally low compared with larger guarding breeds).
  • Jumping/knocking over small children is possible but limited by small size.
  • Zoonotic risks typical of dogs (e.g., parasites) without proper preventive care.
  • Indirect safety risk: heat stress or breathing distress during exertion can lead to sudden collapse requiring urgent human intervention.

The Frenchton is a lovable and loyal small breed designer dog cross-bred from the French bulldog and Boston Terrier. Known for being great family pets, Frenchtons are highly energetic. They make great city pets, just as they also suit apartment dwellers, kids, and the elderly.

Frenchtons were first bred in an attempt to bring positive traits of the Boston terrier and French bulldog together. But they were also bred to eliminate the respiratory problems and other health issues of the French bulldog.

Although no one knows the exact origin, its parent breeds have a clearer background. The Boston terrier was developed in Boston, Massachusetts, in the late 1800s as a new American breed. The French bulldog came from England sometime before 1896. The International Designer Canine Association recognized the Frenchton in 2009 after its alleged origin in America during the 1990s.

Frenchtons are spunky little dogs well-suited to small living spaces and people of all ages. Because the breed does not typically bark much, they will not disturb your neighbors as much as some other breeds. However, they are known for their snoring as much as their loyal and loving cuddles.

The Two Different Types

Because the Frenchton is a crossbreed of the French bulldog and Boston terrier, there is really only one type. But because cross-breeding can lead to very different-looking puppies, it appears there are two. The most common mix is 50% Boston terrier and 50% French bulldog. But the other common type is 75% French bulldog mixed with a 25% French bulldog-Boston terrier mix.

Common names for the Frenchton crossbreed include:

  • Boston Bulldog
  • Boston Frenchie
  • Bulldog Terrier
  • Faux Boston Terrier
  • Faux French Bulldog
  • Frenchbo
  • Froston
  • Frenchie Terrier

Ownership: 3 Pros and Cons

ProsCons
They typically enjoy a long lifespan: Frenchtons commonly live up to 15 years, two years longer on average than a French bulldog. These playful pups can live even longer with a healthy diet and routine exercise.Frenchtons suffer separation anxiety: Frenchtons are not good pets for people who must be away from home for long periods of time because these little dogs suffer separation anxiety. They are typically okay for a few hours but experience anxiety during longer periods of isolation.
Many Frenchtons rarely bark: If you need a dog with a quiet demeanor, such as for apartment dwelling, the Frenchtons might suit. Their infrequent barking means your neighbors will not complain as much as with more vocal dogs like Pomeranians or Huskies.Puppies are usually delivered by C-section: If you plan on breeding your Frenchton, be aware that they often require a veterinarian’s assistance for delivery, as their narrow hips can make natural birthing difficult and increase the risk of complications.
They are great with people of all ages: Frenchtons are very playful and enjoy the company of children. At the same time, this dog enjoys cuddle time and sleeping, making them a docile companion for the elderly. They snore and drool more than other small dogs: Frenchtons bear the facial characteristics of their parents, French bulldogs and Boston terriers. Their flat faces and narrow nasal passages mean they drool after eating, drinking, and exercising. They also snore pretty loudly when sleeping.

Size and Weight

The Frenchton is a small dog, typically standing 11 to 15 inches tall at the shoulder and weighing 15 to 25 pounds. They have a stocky appearance with a sturdy bone structure more like the Boston terrier than the French bulldog.

Common Health Issues

Frenchtons are brachycephalic dogs. This means that they have a short snout inherited from their French bulldog bloodline. With this short snout comes breathing problems, snoring, and problems with keeping cool through panting. As a result of the panting issues, they must be closely watched in hot weather for signs of overheating.

Patellar luxation, a knee joint problem, can cause issues with the knees slipping out of joint. If the Frenchton inherits the French bulldog’s skin folds, this also makes them likely to experience Intertrigo. Intertrigo is an itchy skin rash common to the bulldog breed.

Temperament and Behavior

Some of the best traits of Frenchtons are their spunky personality and pleasant demeanor. It is almost impossible to feel blue around these vibrant little fellows. Words commonly used to describe these small crossbreeds are tolerant, loving, loyal, sweet, affectionate, docile, cuddly, and energetic. Their personalities make them great for families with children, the elderly, apartment dwellers, and people living in bustling cities. Along with a pleasant demeanor, the dog’s tendency is to bark only when alarmed.

Like any puppy, a Frenchton can be difficult to potty train. It can take three to six months to master these important skills. These small dogs exhibit both stubborn and intelligent learning traits. They learn more easily when the lessons are taught in the form of playtime activities.

Care

Compared to many other types of dogs, Frenchton dogs are relatively easy to care for, even by new pet owners. The primary concerns with this breed are keeping up with ear cleaning, claw clipping, routine brushing, and other general care. They rarely have health issues and live long, happy, and energetic lives when they are fed a healthy diet and enjoy regular exercise. However, it is important to remember that a veterinarian’s care is required for birthing. A Frenchton’s small hips do not usually enable it to successfully birth puppies without human intervention.

Frenchtons are relatively easy to maintain.

Best Dog Food

A Frenchton needs to eat about 20 to 25 calories for every pound of body weight. It can eat this food as part of one daily meal or in smaller amounts two or three times per day. The owner can individually decide whether to feed the dog dry food, canned “wet” food, or homemade cuisine.

Whatever type of food they eat, these sturdy little dogs just need a good balance of protein, fiber, and fat. They also need plenty of water, like any dog. Besides these essentials, a Frenchton does not have breed-specific dietary needs, though it’s not a bad plan to customize its diet to the breed’s most common health concerns.

Maintenance And Grooming

Thanks to a short, fairly wiry coat, Frenchtons do not shed very much. They experience some seasonal shedding, such as in the spring. But overall, pet owners do not have to worry about excessive hair left all over the house or on furniture. In fact, Frenchtons shed less than their French bulldog bloodline.

The best grooming routine entails weekly brushing, baths four times per year or as needed, and toothbrushing a few times per week.

Training

Training a Frenchton is not difficult because these small dogs are pretty smart. They are widely considered easy to train compared to most dog breeds. But they can be stubborn or willful. This means that training takes some persistence and positive reinforcement. It also helps to make training a game.

Because Frenchtons are house-dwelling dogs, it is also important to socialize them regularly from the puppy stage. Exposing them to other dogs early will ensure they are amicable and not anxious around other breeds.

Exercise

Frenchtons have spunky personalities but average energy levels. They do not require long walks or other excessive exercises, as primarily house-bound pets. But they do enjoy being outside for a period of time each day and running around to stretch their sturdy legs.

It is particularly important to watch for signs of overheating in these little dogs. Their short snouts make being outside or in a car on hot days less inviting. They easily overheat because panting does not effectively cool them as well as longer-nosed breeds.

Puppies

There are plenty of Frenchton breeders, but it is important to find reputable breeders to ensure the puppy is healthy from the start. If possible, consider taking in a rescue puppy instead of working through breeders. A rescue Frenchton will have high-quality veterinary care, up-to-date vaccinations, and other care before adoption. French bulldog rescue agencies often have Frenchtons and Frenchton puppies available for good homes.

You might want to adopt a Frenchton puppy from a rescue shelter because it can be difficult to find a reputable breeder.

The Frenchton crossbreed is new, having been in existence since the 1990s. Any breeder claiming to have mini versions of these small dogs is probably not exercising quality breeding practices. Although mini Frenchtons are not a major presence on the market, mini breeds often appear in puppy market listings. It is important not to work with a breeder who may put the puppy’s health or well-being at risk.

Coat colors are an important part of puppy adoption decision-making. Many prospective owners have color preferences. These dogs offer a variety of coat color options, most commonly brown, white, cream, blue, black, or brindle.

Children

Frenchtons are excellent pets for children of all ages. Because they are small dogs that enjoy playing, the crossbreeds interact well on the child’s level. They are also loyal but not overprotective. Parents do not typically have to worry about their pup biting or barking at a child. At the same time, Frenchtons do not require much space to run around. They stay close to their family when outside, making it easier for parents to safely keep up with both the off-leash pet and their children.

Despite their short hair and minimal need for grooming and maintenance, these French bulldog-Boston terrier mixes are not hypoallergenic. This means that children with dog allergies will likely have sensitivity to the animal and its hair.

Similar Dogs

Of course, the Frenchton is most similar to its breeds of origin, the French bulldog and Boston terrier. But they are also quite similar to the English Bulldog, Cavalier King Charles Spaniel, and Pekingese.

  • English Bulldog: The English bulldog is known for its wrinkly face, short snout, and short, stocky build, much like the Frenchton. Besides these similarities, both of these breeds are calm, friendly, and loyal. Despite being calm, they also both have spunky personalities.
  • Cavalier King Charles Spaniel: The Cavalier King Charles spaniel is a sweet, loyal, cuddly companion for its owner. Likewise, the Frenchton prefers to stick by its owner’s side, spending lots of time sweetly cuddling on the couch, for a nap or at bedtime.
  • Pekingese: Like the Frenchton, the short-statured Pekingese has a short snout and small, rounded head. Both of these breeds are equally sensitive to heat and require close supervision in hot weather. Each also has a lively, upbeat personality.

Frenchton FAQs (Frequently Asked Questions)

Frenchton puppies cost between $500 and $3500 when bought from a breeder. Of course, you can rescue a Frenchton from an animal shelter or rescue organization for much less, typically as little as under $100. Because they are a small breed and require little food and grooming, you can expect to spend between $50 and $75 per month for food and other needs. Besides the initial cost for a puppy, the biggest expense for these dogs is the veterinarian fee for a C-section delivery of a female’s litter.
