Appearance

Primary Colors
Secondary Colors
Skin Type Brussels Griffon (Canis lupus familiaris) has two coats: rough—harsh, wiry with longer head beard, mustache and eyebrows often hand-stripped—and smooth—short, glossy, easier to groom, sheds more; short-nosed, check face and eyes, no big facial folds.
Distinctive Features
  • Toy companion dog breed developed in Belgium; historically kept for ratting in stables and later as a close human companion (not a hunting 'griffon' type).
  • Very small, compact, square build compared with typical domestic dog forms: selectively reduced size and a more 'neotenous' face (large eyes, short muzzle) distinguish it strongly from many other dog breed morphologies.
  • Brachycephalic head: short muzzle, often with a pronounced stop; can include a slightly undershot jaw, contributing to the characteristic 'grumpy' expression.
  • Large, round, forward-facing eyes are a hallmark; this prominence increases risk of eye trauma/dryness relative to many breeds.
  • Rough-coated individuals show a distinctive beard, mustache, and eyebrow furnishings; smooth-coated individuals lack these but keep the same head shape and expression (reflecting the close relationship among the Brussels Griffon and related varieties).
  • Ears are small; may be carried semi-erect or rose depending on crop status/history-modern dogs are commonly natural-eared.
  • Tail is typically carried up; historically docked in some regions, but natural tails are common where docking is restricted.
  • Breed-typical care needs: frequent dental care due to small jaws/crowded teeth; routine eye cleaning and monitoring for corneal irritation; weight control to reduce orthopedic strain.
  • Common health concerns associated with the breed's conformation and size: brachycephalic obstructive airway syndrome (BOAS)/heat intolerance, dental disease and malocclusion, patellar luxation, and eye problems (corneal ulcers, dry eye/KCS, trauma).

Sexual Dimorphism

Sexual dimorphism is mild; both sexes share the same compact toy build and head type. Differences are primarily in size and robustness rather than coat color/pattern.

♂
  • Often slightly heavier and more muscular with a broader skull and chest within the breed standard range.
  • May show a more pronounced 'head' and jawline appearance due to overall robustness.
♀
  • Often slightly smaller and finer-boned with a somewhat more refined head and lighter frame.
  • May appear more compact and delicate, though overall proportions remain square and sturdy for a toy breed.

Did You Know?

Brussels Griffons are one of three closely related varieties recognized by the FCI: Brussels Griffon, Belgian Griffon, and the smooth-coated Small Brabant Griffon (the same core breed family, differing mainly by coat type and color).

They originated in Belgium and descend largely from small stable dogs used to catch rats-tiny dogs doing real working-dog jobs.

Their hallmark look-very large, forward-facing eyes and a short muzzle-helps explain their famously expressive "human-like" facial expressions.

Coat comes in two main types: rough (wiry) and smooth; rough coats are typically hand-stripped to maintain texture and color.

The breed gained popularity among European city dwellers and was famously kept by Belgium's Queen Marie Henriette, boosting its status as a companion dog.

They're small but often act like a much bigger dog: alert, bold, and quick to sound the alarm despite toy size.

As a domestic dog, they share strong social bonding traits, but selective breeding emphasizes companionship, portability, and a distinctive head/face over hunting endurance.

Unique Adaptations

  • Compact, square build: easy to carry and suited to city living compared with the endurance-oriented build of many ancestral working dogs.
  • Neotenic facial traits (large eyes, short muzzle): a human-preferred "baby-face" look selected over generations for companionship appeal.
  • Coat variety within the griffon group: rough coats provide a wiry, weather-resistant texture; smooth coats are easier to maintain but offer less insulation.
  • Strong human-directed social focus: selection for companionship tends to produce dogs that seek interaction and read human cues intensely.
  • Ratting legacy in a toy package: retains quick reflexes and prey interest while being far smaller than the base species' wild canid relatives.

Interesting Behaviors

  • "Velcro" bonding: commonly follows one favorite person room-to-room and prefers close physical contact.
  • Comedic, expressive communication: frequent head tilts, intense eye contact, and "checking in" with owners-traits reinforced by their prominent eyes and short face.
  • Alert watchdog style: quick to notice door sounds and strangers; may vocalize readily if not trained.
  • Terrier-like pounce-and-shake play: echoes their history as small vermin catchers in stables.
  • Sensitive temperament: often responds best to gentle, consistent training; harsh handling can lead to avoidance or anxiety.
  • High reactivity to novel stimuli: can become timid or barky without early socialization and positive exposure to people, dogs, and city noises.

Cultural Significance

Brussels Griffon, tied to Belgian city life and the griffon companion dog tradition, moved from catching rats in stables to a fashionable late 19th century city pet helped by Belgian royals. Breeders shaped coat and color types into related named breeds.

Myths & Legends

Belgian royal patronage lore: stories and historical anecdotes credit Queen Marie Henriette of Belgium with championing griffon-type dogs, elevating them from stable ratters to salon companions.

Stable-to-parlor origin tale: breed histories often repeat the narrative of the little 'griffon' dogs riding in coaches and living around stables, earning their keep by clearing vermin before becoming prized lap dogs in Brussels households.

The Brussels Griffon’s name brings to mind the European heraldic griffin, making these small, charming dogs seem like storybook, distinctive companions in Victorian-era pet culture.

Old Europeans believed small, watchful lap dogs were kept as alarm pets to warn of strangers or bad luck. This old role shows in the Brussels Griffon (Canis lupus familiaris)'s alert nature.

Behavior & Ecology

Social Pack Group: 3
Activity Diurnal, Crepuscular, Cathemeral
Diet Omnivore Highly palatable animal-protein foods (e.g., chicken or turkey-based complete small-breed kibble/wet food)

Temperament

Highly companion-oriented; seeks frequent contact and reassurance (stronger 'one-person' bonding than the base species' broader pack reliance)
Alert watchdog tendency; quick to notice novelty and may bark readily
Playful and clownish; enjoys short interactive games rather than long endurance exercise
Sensitive to harsh correction; responds best to gentle, consistent training
Can be stubborn/independent in decision-making despite toy size
Often reserved with strangers at first; early socialization reduces fear-based reactivity
Generally good in small spaces when mental stimulation is provided; may develop separation distress if under-enriched
May show prey interest from ratting history (chasing small fast-moving animals) but typically less intense than many terriers

Communication

Sharp, repetitive barking for alerting/attention Breed tends to be more vocal than many larger companion breeds
Whining or 'complaining' sounds when frustrated or seeking contact
Low growls/grumbles during play or when guarding valued resources
Yips/squeaks during high arousal play
Expressive facial signaling Prominent eyes/short muzzle can make gaze and 'mimic-like' expressions especially salient to humans
Close-following, pawing, climbing into laps to initiate contact Affiliative solicitation
Body posture: stiffening and freezing when uncomfortable; may escalate to barking if signals are missed
Scent marking (urination) typical of domestic dogs; may increase with stress or in multi-dog homes
Nose nudges and leaning for reassurance; retreat/hiding when overwhelmed Common in sensitive individuals
Breed-relevant care note affecting communication/behavior: brachycephalic conformation can cause noisy breathing/snorting that may increase with excitement/heat; heat stress can reduce sociability and increase irritability
Health-linked behavior considerations: dental disease (small mouth crowding) can reduce tolerance of handling; patellar luxation may reduce play/exercise willingness; eye irritation can increase blinking/face rubbing-regular vet checks and grooming help maintain normal social behavior

Human Interaction

Domestication Status

Domesticated

The domestic dog (Canis lupus familiaris) is a domesticated subspecies of the gray wolf. The Brussels Griffon was developed in 1800s Belgium from small stable/coach dogs used for ratting and companionship. Breeders crossed with toy breeds like Pug and King Charles Spaniel to make its short face and human-like expression. Today it is a companion toy breed for indoor life.

Danger Level

Low
  • Minor bites/scratches possible if poorly socialized, handled roughly, or fearful; risk increases around children who do not respect small-dog boundaries.
  • Brachycephalic anatomy can predispose to overheating; human risk is indirect (e.g., emergencies during heat exposure).
  • Falls/stepping injuries: due to very small size, accidents more often harm the dog than the human, but can cause trip hazards in tight spaces.

As a Pet

Suitable as Pet

Legality: Brussels Griffon (Canis lupus familiaris) is usually legal as a pet where dogs are allowed. Local rules (licenses, leashes) may apply. Short-muzzled (brachycephalic) dogs may face airline, housing or insurance limits; bans are rare.

Care Level: Moderate

Purchase Cost: $1,500 - $4,500
Lifetime Cost: $18,000 - $45,000

Economic Value

Uses:
Companion animal industry Breeding/show sports Veterinary and grooming services Pet products (food, toys, apparel, carriers)
Products:
  • puppy sales from reputable breeders
  • conformation showing and related services
  • professional grooming (especially for rough-coated lines)
  • pet insurance policies commonly used for toy/brachycephalic breeds
  • training services focused on small-dog manners and separation-related behaviors

Relationships

Quick Take

  • Reaching a 15-year lifespan requires overcoming genetic predispositions inherent to their human-like face.
  • The breed’s petite bone structure directly facilitates the development of syringomyelia within the spinal cord.
  • Counterintuitively, this affectionate companion is prone to fear-based biting when handled by children.
  • The 19th-century pug crossbreeding was necessary to transform the coat of the Smousje.

Originally developed as a mixed breed centuries ago, the Brussels Griffon has been a beloved animal since it first appeared. It is, of course, named after the city of Brussels in Belgium. In the 17th century, the German affenpinscher was bred to the Belgian street dog to produce the Smousje, a small rough-coated dog used to control rodents in stables.

In the 19th century, this dog was crossed with the pug to get a smooth-coated version. The Brussels Griffon is one of the three variations of the Griffon Bruxellois, along with the Belgian Griffon and the Petit Brabancon. The differences are in coat and color only.

The breed almost died out because of the two World Wars, and it is still not common, thus driving up the breeders’ prices, especially for a puppy. Although they are sometimes found in a rescue shelter, genetics plays the biggest role in their health issues and disposition.

This toy dog is quite affectionate and loving, endearing anyone with its bossy personality in such a small size.

3 Pros and Cons of Ownership

Being realistic about any new pet in the family is important. Consider these pros and cons before adopting a Brussels Griffon of your own.

ProsCons
Long lifespan: The Brussels Griffon has an expected lifespan of 12-15 years, which is much longer than many other breeds.Very vocal: While some people don’t mind the volume, the constant alerts whenever a stranger passes may be a little much.
Small size: The Brussels Griffon size is ideal for individuals who must adhere to size limits in their housing.Prone to many health issues: Although the human-like face is appealing to many, the protruding eyes and short nose put this dog at risk for many injuries and illnesses.
Loving: Perhaps the most appealing reason to adopt a Brussels Griffon is its adoration, since they love to be close to their owner.Prone to biting: The sensitive nature of this dog can lead it to become fearful if handled incorrectly, leading it to bite in fear.
Brussels Griffon

Brussels Griffons love exercise but don’t require a ton of space, making them ideal dogs for apartments or small homes.

Size and Weight

The Brussels Griffon is a rather petite dog, which is part of the appeal for owners in apartments or smaller homes. There are no discernible differences between the sizes of females and males, both ranging from 7 to 8 inches tall as adults. In fact, they weigh only about 7 to 12 lbs. when they are fully grown, though some may reach 20 lbs. as a result of the mix of their much larger ancestors.

As a puppy, the Brussels Griffon only weighs a few ounces.

Common Health Issues

Most of the health issues that Brussels Griffons tend to deal with are due to their flat face and their short noses, making the concerns common among other breeds with the same traits. Respiratory issues can occur if the airway is obstructed, but the nose can also lead to eye damage. Some of the eye conditions include glaucoma, cataracts, and progressive retinal atrophy.

Their small bone structure is prone to syringomyelia, which causes the spinal cord to collect fluid-filled cavities. They may also experience patellar luxation, hip dysplasia, and thyroid problems.

Since the Brussels Griffon is not meant to be kept outside, they are more prone to heatstroke than larger breeds. Plus, their short hair prevents them from being in weather that is too cold. Keeping them inside is the easiest way to prevent illnesses from environmental factors.

Temperament

Two Brussels Griffon

Brussels Griffon dogs want to be with their owners all the time, so they can’t be left alone at home much.

Anyone lucky enough to adopt one of these pint-sized pups will have a loyal and sensitive companion. Its naturally affectionate personality makes it incredibly appealing, though that affection may seem a bit dependent. It likes to be as physically close to its owner as possible, which means that separation anxiety is in full swing. If it is possible to bring your dog where you go, you should — it will not be happy at home.

The overall temperament can range broadly, from incredibly outgoing to cautiously shy. However, Brussels Griffons are consistently bossy around the home if they are allowed to run the show. If they feel ignored at any point, they may start behaving badly for attention. However, most of their personality has to do with several factors, like how socialized they are, their training, and the genetics that made them. Remember to be patient as you raise this pup to be a well-balanced pet.

Since the Brussels Griffon is more sensitive than most breeds, they pay clear attention to their surroundings. If they become fearful, their behavior may become prematurely aggressive, biting out of the fear that someone will handle them roughly. With gentle care, it is easy to avoid this issue entirely.

Care

As adorable as the Brussels Griffon can be, it needs to have a certain degree of care to remain healthy and happy. Here are a few tips to properly care for this pet when you bring it home.

Best Dog Food

Since this breed can be prone to obesity, the right portions of high-quality dog food (1/4 to 1/2 cup) are necessary. They should be fed twice daily, and their food should not be left out to graze on for the entire day. However, water should be left out to ensure that they are hydrated.

Maintenance and Grooming

Brussels Griffon Running in the Grass

Brussels Griffons will need to have their hair clipped around the face and removed from the ear canals.

Although the Brussels Griffon is a rather small dog with short hair, it requires quite a bit of upkeep. It may have a rough or smooth coat, depending on the variation of the breed. Regardless of the texture, it is best to brush this dog twice a week to eliminate the fur that it sheds. Baths should occur on an as-needed basis.

The Brussels Griffon with the smooth coat won’t need as much attention to grooming as the wirier breeds, but it’ll shed seasonally. Clipping the short hair is also encouraged every three months, especially around the face. Although this dog will also need its hair from the ear canals removed, this type of care can be done by a veterinarian or a groomer.

Training

The Brussels Griffon’s desire to be close to you can be used to your advantage during training. With exposure to different social settings, such as walks in the park, visits with other people, and interactions with other dogs, you may be able to break its natural shyness around strangers. It tends to enjoy spending time with other pets.

If you are working to teach commands or even just house-train your Brussels Griffon, try to exclusively use positive reinforcement. These puppies are eager to please you, and they want to make you happy. Still, they tend to bark, so they will need a little patience to break this habit.

Exercise

Though the Brussels Griffon is small, it likes a lot of exercise. It should be walked daily, helping it to avoid obesity and keep its stress levels down. Engaging in agility exercises can also fulfill the need for physical activity, especially when temperatures outside are too high for a walk.

Always keep a fenced yard available when you take this dog outside to protect it from predators. However, if you have this type of outdoor area, make sure that there are no sharp objects near the ground that could damage its prominent eyes.

Puppies

Brussels Griffon puppies have a fairly similar demeanor to the adults. When adopting a puppy, you need to have a way for it to interact with other animals and household members early in its life to get the right social skills. It may need a smaller amount of food (1/4 cup) twice a day, but purchase the dry food that is specifically meant for this age for the right nutrition.

Brussels Griffon Puppy

The average litter size of a Brussels Griffon is one to three puppies.

Children

The Brussels Griffon is known for its loving demeanor, but it may not be suited for young children who have yet to be taught the proper interactions with dogs. The dog won’t appreciate the unsolicited hugs, and it doesn’t like to stay in someone’s lap unless it decides to. It especially doesn’t love being hit, chased, or cornered, which may result in growling or snapping.

If you have small children, do not allow them to pick up the dog. Instead, encourage them to be patient and wait for attention, demonstrating a welcoming and calm demeanor. If this pup seems uncomfortable at all, give it a few minutes away from the children to calm down.

Similar Dogs

If the Brussels Griffon just isn’t a good match for your family, there are always the following dogs as well:

  • Pekingese: The human-like face is also found in the Pekingese breed, though there is a lot more grooming involved.
  • Chinese Crested: The Chinese Crested has significantly less fur, but you’ll still have the unique facial hair of the Brussels Griffon.
  • Scottish Terrier: If you like the distinct beard, this sleek and fluffy dog may give you the same compact figure you like as well.

Famous

This species is no stranger to Hollywood. In fact, part of the reason that the Brussels Griffon has gained so much popularity is the result of its featured role in As Good As It Gets.

With such a distinct look, several Brussels Griffons are found on Instagram with quite a following, including @DigbyVanWinkle, @DonnieBarko, and @MyNameIsChamaco.
