A French Bulldog Chihuahua Mix, also called a French Bullhuahua, is a small companion dog bred from a French Bulldog and Chihuahua. It typically weighs 10–30 pounds and stands about 6–12 inches tall, with an affectionate, playful, alert personality. Its health and appearance can vary significantly depending on which parent traits it inherits, particularly regarding breathing and facial structure.

What Is a French Bulldog Chihuahua Mix?
The French Bulldog Chihuahua Mix is a cross between a French Bulldog and a Chihuahua. It is commonly called a French Bullhuahua or Frenchie Chihuahua Mix.
This is not a standardized purebred breed. Instead, it is a mixed breed whose appearance, temperament and health profile can vary considerably from one puppy to another.
That unpredictability is important.
One puppy may look strongly French Bulldog, with:
- a broad head
- bat like ears
- stocky body
- short muzzle
Another may inherit more Chihuahua influence:
- narrower muzzle
- smaller frame
- larger upright ears
- lighter bone structure
And some puppies land somewhere between the two.
The most responsible way to evaluate this mix is therefore to look at both parents, not just photographs of previous puppies.
Why This Mix Is So Popular
The appeal is easy to understand.
You get a small companion dog with the French Bulldog’s clownish personality and the Chihuahua’s alert, confident attitude. Both parent breeds are strongly people oriented, so the mix often forms a very close relationship with its owner.
But there is a tradeoff.
A tiny dog can still have a very big personality.
Some French Bullhuahuas are surprisingly vocal, stubborn and protective of their favorite person. That makes them entertaining companions, but it also means that “small” should never be confused with “easy.”
Appearance and Size
How Big Does a French Bulldog Chihuahua Mix Get?
There is no official breed standard, so adult size varies.
A reasonable expectation is approximately:
| Measurement | Typical Range |
|---|---|
| Height | 6–12 inches |
| Weight | 10–30 pounds |
| Build | Compact to lightly muscular |
| Coat | Short and smooth |
| Ears | Upright, semi upright or Frenchie like |
| Tail | Usually short to moderate |
| Muzzle | Short to moderate |
The French Bulldog itself generally weighs under 28 pounds and stands around 11 to 13 inches, while Chihuahua size is considerably smaller. The resulting mix can therefore have a surprisingly broad physical range.
What Will the Face Look Like?
This is one of the hardest characteristics to predict.
Some puppies inherit the French Bulldog’s:
- broad skull
- shortened muzzle
- facial wrinkles
- bat ears
Others inherit more Chihuahua influence:
- longer muzzle
- narrower head
- prominent eyes
- larger upright ears
This matters for health as well as appearance.
A puppy with a less extreme, more open airway may have different respiratory risks than a puppy with a very shortened muzzle.
Temperament and Personality
The French Bullhuahua is usually affectionate, people oriented and playful, but it can also be stubborn and surprisingly assertive.
The Chihuahua side may contribute:
- alertness
- confidence
- territorial behavior
- vocal tendencies
The French Bulldog side often contributes:
- affection
- playfulness
- adaptability
- strong human attachment
The result can be a dog that follows you from room to room and then suddenly decides that your training session is over.
Are French Bullhuahuas Affectionate?
Usually, yes.
Many become extremely attached to one or two people.
That can be wonderful for owners who want a close companion, but it creates another responsibility: independence training.
A dog that is constantly carried, comforted and entertained can struggle when left alone.
Are They Aggressive?
Not inherently.
However, small dogs sometimes develop defensive behavior when owners allow them to repeatedly bark, lunge or snap because their behavior seems harmless due to their size.
The better goal is calm confidence.
Teach the puppy that:
- strangers are normal
- visitors are not threats
- other dogs do not need to be challenged
- barking is not always necessary
French Bulldog Chihuahua Mix With Children
A well socialized French Bullhuahua can be a good family companion, but supervision is important.
The main concern is not necessarily aggression.
It is size.
A small dog can be injured accidentally by:
- rough handling
- falling
- being stepped on
- being picked up incorrectly
Young children should learn how to interact gently.
Best Family Environment
This mix tends to work particularly well with:
- older children
- calm families
- couples
- singles
- apartment residents
Homes with very young children require more active supervision.
French Bulldog Chihuahua Mix With Other Dogs and Pets
Early socialization can make a major difference.
Some individuals are friendly with other dogs, while others inherit the Chihuahua’s tendency to be suspicious or selective.
Introduce new animals gradually.
Do not assume that because the dog is small, it will automatically get along with every other pet.
The same principle applies to cats.
A confident puppy with a strong prey drive can still chase a cat despite weighing only a fraction of the cat’s size.
Exercise Needs
This is generally a moderate activity companion rather than an endurance dog.
A healthy adult may enjoy:
- short walks
- indoor games
- training exercises
- sniffing activities
- interactive toys
The important word is short.
If the puppy inherits a very short French Bulldog type muzzle, breathing limitations can become more important than cardiovascular fitness.
French Bulldogs are particularly vulnerable to heat and breathing problems because of their brachycephalic anatomy.
A Better Exercise Strategy
Instead of one exhausting walk, consider:
Morning:
Short sniffing walk
Afternoon:
Indoor training or puzzle activity
Evening:
Short relaxed walk and play
During hot or humid weather, exercise should be reduced and carefully monitored.
Panting excessively, struggling to breathe, weakness or collapse are not signs of a dog simply “getting tired.”
They require immediate attention.
Puppy Development Timeline
French Bulldog Chihuahua Mix puppies can develop at different rates because they inherit genes from two distinctly sized breeds.
Birth to 3 Weeks
The puppy is almost entirely dependent on its mother.
Development focuses on:
- nursing
- weight gain
- neurological development
- early movement
At this stage, predicting adult appearance is extremely difficult.
3 to 8 Weeks
This is an important social development period.
Puppies begin:
- walking confidently
- playing with littermates
- exploring their environment
- learning bite inhibition
Responsible breeders should expose puppies to safe, controlled household experiences rather than keeping them isolated.
8 to 12 Weeks
This is when the puppy enters its new owner’s home in many cases.
Priorities include:
- toilet training
- gentle handling
- name recognition
- positive crate training
- controlled socialization
Do not overwhelm a small puppy with dozens of unfamiliar experiences in a single day.
3 to 6 Months
The puppy becomes much more curious.
You may notice:
- increased confidence
- chewing
- selective listening
- stronger attachment
- early territorial behavior
This is an excellent period for basic obedience.
6 to 12 Months
Adolescence begins.
The dog may suddenly:
- ignore previously learned commands
- bark more
- test boundaries
- become more independent
This does not mean training has failed.
Consistency matters more than punishment.
12 Months and Beyond
Most French Bullhuahuas are approaching adult size by this stage, although individual development varies.
The dog’s adult personality also becomes clearer.
Some become calm lap companions.
Others remain energetic, vocal and constantly involved in household activity.
Training a French Bulldog Chihuahua Mix
Training difficulty is usually moderate.
Both parent breeds are intelligent, but neither is famous for automatic obedience.
The Chihuahua may bring:
- independence
- stubbornness
- selective attention
The French Bulldog may bring:
- food motivation
- playfulness
- occasional stubborn behavior
That combination rewards patience.
Best Training Method
Use:
- short sessions
- high value rewards
- repetition
- clear boundaries
- positive reinforcement
Avoid turning training into a battle of wills.
Five minutes of successful training is more useful than twenty minutes of frustration.
What to Teach First
Prioritize:
- Name recognition
- Recall
- Sit
- Down
- Leave it
- Loose leash walking
- Quiet behavior
- Calm greetings
- Alone time
The last two are particularly important for a dog that may become intensely attached to its owner.
Grooming Requirements
The coat is generally easy to maintain.
Weekly Care
Most dogs need:
- brushing
- nail checks
- ear inspection
- dental care
Facial Folds
If your puppy inherits significant French Bulldog facial wrinkles, keep the folds clean and dry.
Moisture trapped in skin folds can contribute to irritation and infection.
Dental Care
Small dogs can be particularly challenging when it comes to dental hygiene.
Start brushing early rather than waiting until adulthood.
Health and Genetics
This is the section prospective owners should read carefully.
A mixed breed is not automatically healthier simply because it is a cross.
The French Bulldog parent can contribute significant health concerns, particularly when the puppy inherits pronounced brachycephalic anatomy.
French Bulldogs are predisposed to airway problems, heat intolerance, skin disease and other conditions associated with their body structure.
Brachycephalic Airway Risk
This is one of the biggest questions when evaluating a French Bulldog Chihuahua Mix.
Not every French Bullhuahua has the same muzzle shape.
A puppy with a very short, compressed muzzle may have greater respiratory risk than one with a more moderate facial structure.
Watch for:
- loud breathing while awake
- excessive snoring
- exercise intolerance
- overheating
- difficulty recovering after activity
A Chihuahua influence may produce a somewhat longer muzzle in some puppies, but it should never be assumed to eliminate French Bulldog related airway problems.
Eye Problems
Depending on inherited facial structure, some dogs may be prone to eye irritation or injury.
Watch for:
- excessive tearing
- squinting
- redness
- cloudiness
- rubbing the face
Skin Problems
French Bulldog genetics can contribute to:
- allergies
- skin inflammation
- yeast infections
- fold irritation
The risk varies considerably between individuals.
Patellar Problems
Small dogs can be predisposed to patellar luxation.
Ask the breeder about orthopedic screening where appropriate.
Dental Crowding
A small jaw combined with crowded teeth can make dental disease easier to develop.
Regular veterinary dental evaluation is worthwhile.
Health Testing Before Buying
Do not ask a breeder only:
“How much is the puppy?”
Ask:
“What health testing was performed on both parents?”
Look for evidence relating to:
- patella health
- airway structure
- orthopedic health
- eye health
- genetic conditions relevant to the parents
- overall veterinary examination
A breeder who cannot clearly explain the health history of both parents deserves extra scrutiny.
French Bulldog Chihuahua Mix vs French Bulldog
| Trait | French Bulldog | French Bulldog Chihuahua Mix |
|---|---|---|
| Size | Small | Small, but more variable |
| Muzzle | Usually very short | Can range from short to moderate |
| Personality | Affectionate, playful | Affectionate, alert, sometimes more vocal |
| Energy | Low to moderate | Moderate |
| Training | Moderate | Moderate |
| Barking | Usually moderate | Can be higher |
| Heat Sensitivity | Significant concern | Depends on facial structure |
| Appearance | More predictable | Much more variable |
| Health | Known breed specific risks | Risks inherited from both parents |
The biggest advantage of the mix is also its biggest uncertainty: you cannot predict every physical trait from the parents with complete accuracy.
French Bulldog Chihuahua Mix vs Chihuahua
| Trait | French Bulldog Chihuahua Mix | Chihuahua |
|---|---|---|
| Build | Usually stockier | Usually lighter |
| Personality | Playful and affectionate | Alert and often highly confident |
| Exercise | Moderate | Moderate |
| Size | Usually larger | Usually smaller |
| Facial Shape | Variable | Usually more defined Chihuahua type |
| Training | Moderate | Can be stubborn |
| Watchdog Instinct | Moderate to high | Often high |
Common Mistakes Owners Make
Treating a Small Dog Like a Toy
A French Bullhuahua still needs:
- boundaries
- training
- socialization
- exercise
Carrying the dog everywhere can prevent healthy confidence.
Overlooking Breathing Problems
Snoring may look cute.
Difficulty breathing is not.
Owners should learn the difference between normal sleep noises and respiratory distress.
Overfeeding
Because the dog is small, even a few extra pounds can significantly affect body condition.
Keeping the dog lean is especially important when respiratory or orthopedic concerns exist.
Ignoring Separation Anxiety
A dog that follows you everywhere may look adorable.
But excessive dependence can become a problem.
Teach independence from puppyhood.
Assuming Hybrid Means “Healthier”
Crossbreeding does not guarantee health.
A puppy can inherit significant problems from either parent.
Insights Most Articles Miss
The Muzzle Matters More Than the Label
“French Bulldog Chihuahua Mix” tells you the parents.
It does not tell you exactly how short the puppy’s muzzle will be.
When evaluating health, look at the actual puppy.
Weight Matters More Than Many Owners Realize
A slightly overweight small dog can experience much greater physical strain than an owner expects.
Body condition should be evaluated rather than relying only on the number on a scale.
Personality Can Be Very Chihuahua Like
Some puppies look almost entirely French Bulldog but behave like a Chihuahua.
Expect:
- alertness
- confidence
- barking
- strong attachment
Do not choose the mix solely because you expect a quiet Frenchie personality.
Is a French Bulldog Chihuahua Mix Good for Apartments?
Usually, yes.
Its compact size and moderate exercise requirements can make apartment living practical.
But there are three things to consider:
Noise
A Chihuahua influenced dog can be vocal.
Heat
Poor ventilation and hot weather can be dangerous for dogs with shortened airways.
Alone Time
A strongly people oriented dog may struggle if routinely left alone for long periods.
Apartment suitability therefore depends more on the owner’s routine than square footage alone.
Nutrition and Weight Management
Feed according to:
- age
- size
- body condition
- activity
- veterinary recommendations
Do not judge food requirements by the French Bulldog parent alone.
The Chihuahua side can produce a smaller dog with substantially lower calorie requirements.
Keep the Body Lean
You should be able to:
- feel the ribs without excessive pressure
- see a waist from above
- identify a slight abdominal tuck
Maintaining healthy body condition is especially important for a dog with potential respiratory or orthopedic limitations.
Buyer Warning
Be Careful With “Rare” French Bullhuahua Marketing
Some sellers may advertise puppies using phrases such as:
- micro French Bullhuahua
- teacup Frenchie Chihuahua
- rare miniature Frenchie Chihuahua
- exotic color French Bullhuahua
Treat these claims carefully.
There is no need to deliberately select extreme smallness.
The better question is:
Is the puppy structurally sound, breathing comfortably and coming from health tested parents?
That is far more meaningful than a marketing label.
Responsible Breeder Checklist
Before paying a deposit, ask:
About the Parents
☐ Can I meet the mother?
☐ Can I see the father or reliable health information about him?
☐ What health testing has been completed?
☐ Are there known breathing problems?
☐ Are there orthopedic concerns?
About the Puppies
☐ Has a veterinarian examined the litter?
☐ Are vaccination and deworming records available?
☐ Has the puppy been properly socialized?
☐ Can I see where the puppies were raised?
☐ Is the breeder willing to take the dog back if circumstances change?
A responsible breeder should be interested in whether you are suitable for the puppy, not simply whether you can pay.

Frequently Asked Questions
What is a French Bulldog Chihuahua Mix called?
The mix is commonly called a French Bullhuahua or Frenchie Chihuahua Mix. It is a cross between a French Bulldog and a Chihuahua.
How big does a French Bulldog Chihuahua Mix get?
Most published guides place them around 6 to 12 inches tall and 10 to 30 pounds, although individual dogs can fall outside those ranges.
Is the French Bullhuahua a good family dog?
It can be, particularly with older children and proper socialization. Its small size means young children should be supervised carefully.
Are French Bullhuahuas easy to train?
They are intelligent but can be stubborn. Short, positive and consistent training sessions generally work better than harsh correction.
Do French Bulldog Chihuahua Mixes have breathing problems?
They can. The risk depends heavily on inherited facial structure. A puppy with a very shortened muzzle may retain significant brachycephalic airway risk from its French Bulldog parent. French Bulldogs are well known for airway and heat tolerance concerns.
Are French Bullhuahuas good apartment dogs?
Usually, yes. Their small size and moderate activity needs can work well in apartments, provided barking, exercise, temperature control and alone time are managed properly.
How long does a French Bulldog Chihuahua Mix live?
Published estimates vary because this is not a standardized breed, with some current guides reporting approximately 12 to 18 years. Individual lifespan depends heavily on genetics, body condition, inherited health problems and veterinary care.
Are French Bulldog Chihuahua Mixes hypoallergenic?
No. Neither parent is considered a truly hypoallergenic breed, and the mix can still shed allergens through dander and saliva.
Is a French Bullhuahua healthier than a French Bulldog?
Not automatically. Mixing breeds can introduce genetic diversity, but it does not guarantee that a puppy avoids French Bulldog health problems. The individual puppy’s structure and the health of both parents matter more than the “mixed breed” label.
Final Verdict
The French Bulldog Chihuahua Mix is a small dog with a surprisingly large personality. It can be affectionate, funny, loyal and highly entertaining, while still bringing enough Chihuahua confidence to keep its owner on their toes.
But this is not a mix to choose purely because the puppies look cute.
The smartest buyer evaluates:
breathing → structure → temperament → health testing → breeder quality → appearance
in that order.
If you want a compact companion that enjoys human company and fits comfortably into a smaller home, the French Bullhuahua can be an excellent match. Just remember that its small body does not eliminate the responsibilities of responsible dog ownership.
