The Brussels Griffon presents one of the most distinctive and immediately recognizable appearances in the canine world, combining toy-sized stature with outsized personality visible in every aspect of their physical structure. This small breed typically stands between nine and eleven inches at the shoulder, with weight ranging from eight to twelve pounds, creating a compact, sturdy package that belies their surprisingly robust constitution. The overall impression is of a small but sturdy dog, nearly square in proportion, with a distinctive head that commands immediate attention and creates the breed's unforgettable expression.
The head of the Brussels Griffon stands as the breed's most defining feature, large in proportion to body size and creating the almost human-like expression that has captivated admirers for over a century. The skull is broad and domed, with a rounded forehead that creates a very pronounced stop where the muzzle meets the skull. This dramatic stop, combined with the extremely short muzzle, gives the breed its characteristic pushed-in face that places it firmly in the brachycephalic category. The muzzle measures only about one inch in length, approximately one-third of the distance from nose tip to occiput, creating the flat-faced appearance that contributes to both the breed's charm and certain health considerations.
The eyes are arguably the Brussels Griffon's most expressive feature, large, round, and set wide apart on the face. They should be dark in color, preferably black, and possess an almost jewel-like quality that seems to reflect intelligence and emotion in equal measure. The eyes are prominent but should not bulge excessively, though their size and placement make them somewhat vulnerable to injury. Long, black eyelashes frame the eyes, adding to the human-like quality of the breed's expression. The eyes convey alertness, curiosity, and often an amusing air of self-importance that endears the breed to enthusiasts.
The nose must be black, very short, and positioned so that the tip is set back deeply between the eyes. The nostrils are wide and open, though the extreme shortening of the muzzle means breathing considerations require attention. The nose leather itself should be broad, and any color other than black is a serious fault in breed standards. The jaw structure contributes significantly to the breed's unique appearance, with the lower jaw being slightly undershot, meaning it projects slightly beyond the upper jaw. This undershot bite should be clean, with incisors of the lower jaw placed in a straight line and neither teeth nor tongue showing when the mouth is closed. The chin is prominent and should be underlined, creating definition in profile.
Ear set and carriage vary depending on whether ears are natural or cropped, though many countries now prohibit ear cropping. Natural ears are small, semi-erect, and set high on the skull, dropping forward with the tips pointing toward the eye area. When cropped, ears stand erect and are pointed, though this practice is increasingly rare and controversial. The head is made more expressive by slight wrinkling of skin across the forehead, particularly when the dog is alert or attentive, though excessive wrinkling is not desirable.
The body of the Brussels Griffon is compact and nearly square, presenting a sturdy, thickset appearance despite the small overall size. The neck is of medium length and arches slightly, flowing smoothly into well-laid-back shoulders. The chest is broad and deep, with the brisket extending to the elbows, providing ample room for heart and lungs despite the breed's diminutive stature. The ribs are well sprung, creating a rounded thorax that contributes to the breed's robust appearance. The back is short and level, supported by strong loins that provide power despite the small frame. The overall body structure creates a balanced, athletic appearance that allows for surprising agility and endurance.
The forequarters feature straight, medium-length legs with good bone for the size of the dog. The shoulders are well laid back, allowing for efficient movement and reach. Elbows fit close to the body, and pasterns are short and strong, neither knuckling over nor breaking down. The feet are small, round, and compact, with thick pads and well-arched toes that point straight ahead. The hindquarters are well angulated, with strong, muscular thighs and well-bent stifles. The hocks are well let down and perpendicular when viewed from behind. The rear feet match the front in compactness and construction.
The tail is set high and carried upward, either straight or slightly curved over the back. Traditionally, tails were docked to approximately one-third of natural length, though natural tails are increasingly common and accepted as tail docking becomes less prevalent worldwide. Whether natural or docked, the tail should be carried jauntily, contributing to the breed's alert, self-assured demeanor.
Coat texture and length represent the most significant variation within the breed, dividing Brussels Griffons into two distinct types. The rough coat variety features wiry, dense fur that is harsh to the touch, with the wirer the texture, the better according to breed standards. This coat type requires hand-stripping to maintain proper texture, as clipping softens the coat unacceptably. The rough coat is slightly longer around the face, forming distinctive eyebrows, beard, and mustache that frame the expressive features and create the breed's characteristic monkey-like appearance. The smooth coat variety presents an entirely different look, with straight, short, tight, glossy hair that lies flat against the body. This coat requires minimal grooming compared to the rough variety and sheds seasonally, typically for brief periods in spring and fall.
Color variations add further diversity to the breed's appearance. Red coats range from reddish-brown to rich mahogany, with darker shades generally preferred. Belge coloring presents a fascinating mix of black and reddish-brown hairs creating a unique appearance. Black and tan dogs show black bodies with rich tan markings in specified locations including cheeks, legs, and above the eyes. Solid black dogs are entirely black without any tan or red hairs. Regardless of color, a small white chest marking is permissible though not preferred, and white markings elsewhere constitute a serious fault.
Adaptability
★★★★★
The Brussels Griffon adapts remarkably well to various living situations, particularly apartment living due to their small size. They thrive in both urban and suburban environments as long as their exercise and companionship needs are met. However, they struggle with being left alone for extended periods and need families who can provide near-constant companionship or take them along on daily activities.
All Around Friendliness
★★★★★
Brussels Griffons are exceptionally affectionate with their families, forming deep bonds that border on inseparable attachment. While they may be initially reserved with strangers, they typically warm up quickly once properly introduced. Their friendliness is genuine and heartfelt, though they often select one favorite person in the household to whom they show particular devotion and attachment.
Health and Grooming Needs
★★★★★
Grooming requirements vary significantly between the two coat types. Rough-coated Brussels Griffons need regular brushing twice weekly and periodic hand-stripping to maintain proper coat texture, while smooth-coated varieties require only quick weekly brushing. Both types benefit from regular facial cleaning around their expressive eyes and short muzzles. While generally healthy, owners must monitor for breed-specific conditions related to their brachycephalic facial structure.
Trainability
★★★★★
Brussels Griffons possess keen intelligence and learn quickly, but their sensitive nature and occasional stubborn streak require patient, positive training methods. They respond best to gentle guidance with treats and praise rather than harsh corrections which can damage their confidence. Their desire to please their favorite person aids training, though they may need extra time to master commands compared to more eager-to-please breeds.
Exercise Needs
★★★★★
Despite their small size, Brussels Griffons maintain surprisingly active dispositions and need regular daily exercise. A combination of short walks totaling 30-45 minutes daily plus indoor play sessions keeps them physically fit and mentally stimulated. They enjoy interactive games and can be quite playful, though their exercise tolerance is limited by their brachycephalic structure and small stature.
Social Needs
★★★★★
This breed has extraordinarily high social needs and genuinely requires near-constant human companionship. Brussels Griffons have earned the nickname Velcro dogs for their tendency to remain glued to their favorite person throughout the day. They suffer genuine distress when left alone for extended periods, making them unsuitable for people with full-time jobs unless the dog can accompany them or doggy daycare is available.
Apartment Friendly
★★★★★
Brussels Griffons excel as apartment dogs due to their compact size, moderate exercise needs, and generally quiet indoor demeanor. They require no yard and are perfectly content with walks and indoor play for exercise. Their small size means they take up minimal space, and while they will bark to alert their owners, excessive barking is uncommon when their companionship needs are met.
Grooming
★★★★★
Grooming demands depend entirely on coat type. The rough coat requires more intensive maintenance including twice-weekly brushing, periodic professional hand-stripping, and careful attention to the longer facial furnishings. The smooth coat needs only weekly brushing and occasional baths. Both varieties require regular facial cleaning, nail trimming, teeth brushing, and ear checks, making their overall grooming needs moderate but manageable.
Stranger Friendly
★★★★★
Brussels Griffons approach strangers with initial caution and reservation, preferring to assess newcomers before committing to interaction. Once they determine someone poses no threat, they often warm up and may even seek attention. Early socialization significantly improves their comfort level with new people, though they will always bond more deeply with their own family members than with casual acquaintances.
Barking Tendencies
★★★★★
Brussels Griffons serve as excellent little watchdogs, alerting their owners to unusual sounds or approaching visitors with purposeful barking. While not chronic barkers compared to some toy breeds, they will vocalize when they perceive something noteworthy. Training can help manage excessive barking, and meeting their exercise and attention needs prevents boredom-related nuisance barking. Their alert nature means they notice everything happening in their environment.
Cat Friendly
★★★★★
Most Brussels Griffons coexist peacefully with cats, especially when raised together from puppyhood. Their low prey drive and generally social nature means they view cats as companions rather than targets for chase. Many Brussels Griffons actively enjoy feline companionship, often snuggling together and playing gently. Their small size makes them less intimidating to cats than larger breeds, facilitating easier acceptance.
Dog Friendly
★★★★★
Brussels Griffons generally get along well with other dogs in their household, particularly when properly socialized from puppyhood. However, they completely lack awareness of their small size and may attempt to dominate much larger dogs, potentially creating dangerous situations. Careful supervision during interactions with large or unfamiliar dogs prevents accidents. With proper introductions and ongoing socialization, they can be friendly and playful with appropriate canine companions.
