The Brussels Griffon's appearance is immediately striking and difficult to forget. This is a small dog - 8 to 10 pounds in ideal condition, 7 to 10 inches at the shoulder - but it carries itself with an attitude of self-importance that makes it feel larger than its dimensions suggest. The overall structure is square: height roughly equal to body length, with a compact, well-muscled body that is neither delicate nor refined in the way some toy breeds are. There is substance here despite the small scale.
The head is the breed's most defining feature and the source of its famously expressive, almost human face. The skull is large and domed - notably round when viewed from the front, with a prominent dome that gives the Griffon a uniquely high-browed appearance. The forehead is high and broad, the eyes are set wide apart and positioned frontally rather than to the sides of the skull, and the combination produces a facial structure that some people find endearing and others find unsettling in its human resemblance. The stop is very deep, producing the short, pushed-in face that is central to the breed's type.
The muzzle is very short, broad, and turned up at the end - technically upturned rather than flat in the same way as a Pug or Bulldog, which gives the Griffon its characteristic chin-forward, slightly chin-up expression. Technically this is a brachycephalic (shortened skull) structure, which has meaningful health implications. The chin should be prominent and wide, and when the mouth is closed, neither upper nor lower teeth should be visible. The nose is set high on the face and should be very short from back to tip.
The eyes are perhaps the breed's most captivating feature. Large, wide-set, and very dark, they give the Brussels Griffon the direct, aware, and emotionally communicative expression that has earned comparisons to Ewoks, monkeys, and elderly humans by turns. The expression should be bold and direct - not soft or vague. Eye rims should be black and tight fitting. Any sign of bulging or rolling outward from the socket is a fault; the brachycephalic structure that produces the large eyes also makes them vulnerable to injury and requires attentive care.
Ears are set high on the skull and, in uncropped dogs (which is now the standard in most countries), are small and semi-erect - folding forward and down at the tip rather than standing fully erect or flopping completely. Ear cropping was historically practiced in Belgium and produced the fully erect ear that appears in vintage photographs of the breed, but is rarely done today in the United States and is prohibited in many countries.
The neck is short and thick, connecting the distinctive head to a compact, well-sprung body. The chest is wide and well ribbed, the back is short and level, and the body has a stocky substance unexpected in a toy breed. The hindquarters are strong and well-muscled relative to the dog's size, providing the driving power for movement that should appear smooth and purposeful despite the small scale.
The tail is typically docked to about one-third its natural length in countries where docking is legal, and carried high when the dog is active. In countries where docking is prohibited, the natural tail is medium length and carried upright over the back without curling excessively. Either presentation is correct by the standard in its applicable context.
The two coat types create two very different visual impressions from the same underlying dog. The rough-coated Griffon carries a wiry, dense, harsh coat with the characteristic facial fringe - beard, mustache, and bushy eyebrows - that gives it its famously theatrical expression. The coat on the body is dense but not overly long, with a harsh wire texture that should feel quite different from the soft, cottony texture of a poor-quality coat. The smooth-coated variety (Petit Brabancon in FCI terminology) has a close-lying, short, glossy coat with no furnishings on the face, presenting a much cleaner, almost slick appearance that emphasizes the round head and large eyes without the theatrical framing of the rough coat. Both are genuinely beautiful dogs, just in very different ways.
Colors include red (the classic reddish-brown), belge (a grizzled mixture of red and black that produces warm tones with darker shading), black and tan, and solid black. All colors can appear in both coat types.
Movement should be purposeful and free despite the dog's compact, short-legged build. The Griffon should not appear to roll or waddle, nor should it move with a stilted, high-stepping gait. Reach and drive should be adequate for a dog of its dimensions, and the overall impression in motion should be of a confident, capable small dog rather than one struggling with its own construction. Poor front angulation, a common fault in toy breeds, produces a choppy, restricted front movement that is easy to spot in comparison to the correct, ground-covering reach of a properly built Griffon.
Affectionate With Family
★★★★★
The Brussels Griffon is intensely bonded to its primary person and wants to be in physical contact or immediate proximity at all times. This is not casual affection - it is devotion.
Good With Young Children
★★☆☆☆
The Griffon's small size makes it fragile around young children who play roughly, and its sensitive personality means it handles chaotic, high-energy environments poorly. Better matched with older, calmer children.
Good With Other Dogs
★★★☆☆
Typically sociable with other dogs, especially those of similar size. Its self-important attitude means it may challenge dogs much larger than itself, which requires owner awareness.
Shedding Level
★★☆☆☆
Rough-coated Griffons shed minimally; smooth-coated (Petit Brabancon) variety sheds more noticeably. Neither coat type produces significant hair accumulation on furniture.
Coat Grooming Frequency
★★★☆☆
Rough-coated Griffons require hand-stripping several times yearly to maintain correct coat texture; smooth varieties need only weekly brushing. Neither requires professional clipping if maintained properly.
Drooling Level
★★☆☆☆
Occasional drooling associated with the brachycephalic facial structure, particularly when anticipating food or after drinking. Not a significant drooling breed overall.
Coat Type
★★★☆☆
Two distinct coat types exist in the same breed: rough (wiry, harsh, requiring hand-stripping) and smooth (short, tight, minimal maintenance). Both are accepted within the breed standard.
Openness To Strangers
★★☆☆☆
Reserved and often aloof with unfamiliar people - the Griffon chooses its person carefully and is not inclined to perform for anyone else. Proper socialization moderates but does not eliminate this selective nature.
Playfulness Level
★★★★☆
Playful and entertaining in a self-directed, quirky way that reflects the breed's considerable personality. It invents its own games and brings intensity to play sessions that belies its small size.
Watchdog/Protective Nature
★★★★☆
An enthusiastic alarm dog that will announce arrivals with conviction. The Griffon's suspicion of strangers and vocal response make it an effective alerting dog despite its tiny stature.
Adaptability Level
★★★★☆
Adapts well to apartment living and various household sizes provided it has sufficient human companionship and moderate daily activity. Its small size makes it genuinely portable.
Trainability Level
★★★☆☆
Intelligent enough to learn quickly but independent enough to decide when cooperation is worth its while. Positive reinforcement works well; any harshness produces a dog that simply withdraws.
