Brussels Griffon.

FCI 80/81/82: small guardian and companion dog; stable ratter and carriage guard in its history. UKC: Belgian stable ratters and guardians of horse-drawn cabs. AKC page: from rough-and-tumble rat dog (griffon d'ecurie) to laptop companion. AKC standard: a toy dog, alert, with an almost human expression. RKC: one early role was as watchdog in stables, where he could also keep down rodents..

Breed sets the odds. The parents set the dog. Every number here shows its source, its spread and how sure we are. Nothing on this page is a prediction about one dog.

The body

What the breed is built like. Registry standards give an ideal, not a range.

Height at the shoulder

7 to 11 in

Breed clubAKC

One breed-wide range counted in both sexes (no standard splits by sex). The registry page and Wikipedia differ; both shown, never averaged. FCI 80, 81 and 82 share one standard text; none of the three prints a height.

Weight

5 to 15 lb

Breed clubAKC breed standard, 2022

Low and high span every cited figure (AKC About text 5 to 15 lb; FCI 3.5 to 6 kg = 7.7 to 13.2 lb). The AKC and UKC standards agree on 8 to 10 and a 12 lb ceiling; the FCI sits higher, and the AKC page's own About text is wider than its header. All shown. The three FCI breeds share one standard so the one size figure is cited for all of them. No single ideal is printed, so center is blank.

Coat

AKC: two coat types, rough (wiry and dense, hand-stripped, no silky or woolly hair) or smooth (straight, short, tight, glossy); otherwise no difference. Colours: red; belge (black and reddish brown mixed); black and tan; solid black. White spot or blaze is a disqualification. UKC: rough and smooth, shown together; wiry, dense and double rough coat; silky or woolly is a serious fault. FCI 80/81/82: three breeds by coat and colour. Griffon Bruxellois is rough and red; Griffon Belge is rough and black or black and tan; Petit Brabancon is smooth (at most 2 cm), same colours as the Griffons with a dark mask. RKC: two varieties; the rough is the usual one.

Breed clubAKC breed standard, 2022

The AKC and UKC treat all coats and colours as one breed; the FCI splits it into three. The FCI standard text is shared across 80, 81 and 82.

Shedding

RKC: sheds. AKC breed page: smooth coat sheds, with a heavier shed of a week or two in the spring and again in the fall; rough-coated Griffons do not shed. AKC band: shedding level 3 of 5.

Breed clubThe Royal Kennel Club

Registry statements; no study opened.

Heat tolerance

2 of 5 · AKC breed page: like all flat-faced breeds, Brussels Griffons can experience breathing problems in sunny, hot or humid weather, and usually snore. AKC standard: nose extremely short, set back between the eyes with lay-back; undershot jaw. UKC: head properties should remain free of exaggeration so as to not compromise breathing. RKC: Breed Watch category 2; brachycephalic, with a BOAS breathing test newly recognised (August 2026). Coats: smooth is short and tight; rough is wiry and dense (UKC: double).

DerivedAKC

Derived. The dog is brachycephalic (sources state it), which pulls the score down; the coat (short smooth, or wiry rough) alone would sit higher. Held at 2 as a flagged judgement. No heat-illness study was opened.

How long they live, and what they cost

Measured on real dogs, with the sample and the spread. Never a guess.

Median lifespan

13.3 years (12.7 to 13.9)

MeasuredMcMillan KM, 2024

McMillan et al. 2024 / Dogs Trust table. UK population; the table lists one Brussels Griffon row. The AKC page 12 to 15 year band is a band, not a median, and is not used here.

The dog at home

What the breed asks of a day. The first thing most homes get wrong.

Exercise need

RKC: up to 30 minutes per day; suits a flat or apartment; town or country; small to medium garden. AKC breed page text: at least a half-hour of moderate exercise a day.

Breed clubThe Royal Kennel Club

RKC is a UK registry band, mapped by the library rule (up to 30 = 30). The AKC text agrees.

Exercise need

AKC breed page: need at least a half-hour of moderate exercise daily; love to romp and play and are happiest doing things with their people; excel in obedience, agility and tracking; a low threshold for loneliness. AKC bands: energy level 3 of 5, mental stimulation needs 3 of 5, playfulness 4 of 5, barking level 4 of 5. RKC: up to 30 minutes per day.

Breed clubAKC

AKC bands are not mapped to minutes; RKC supplies the minutes figure.

Energy

3 of 5

Breed clubAKC

AKC breed page trait score, 1 to 5: a breed-club tendency, never a measurement.

Grooming load

3 of 5 · RKC: grooming more than once a week; coat length medium; sheds. AKC breed page: smooth coat needs weekly brushing (daily during the spring and fall shed, a week or two each); rough coat does not shed and many owners clip it short except the beard, or use a groomer. AKC standard: rough coat is hand-stripped and never unkempt; coats prepared with scissors or clippers are severely penalized in the show ring. FCI: rough coat is trimmed. UKC: rough coat is wiry, dense and double.

Breed clubThe Royal Kennel Club

RKC band mapped by the library rule (more than once a week = 3). The rough coat for the show ring (hand-stripping) needs more skill than the figure suggests; the AKC page's weekly brushing for the smooth coat agrees.

The work

What it was built to do in the field, and what a test or trial asks of it.

Role

FCI 80/81/82: small guardian and companion dog; stable ratter and carriage guard in its history. UKC: Belgian stable ratters and guardians of horse-drawn cabs. AKC page: from rough-and-tumble rat dog (griffon d'ecurie) to laptop companion. AKC standard: a toy dog, alert, with an almost human expression. RKC: one early role was as watchdog in stables, where he could also keep down rodents.

Breed clubFCI-Standards N 80 Griffon Bruxellois, 2003

Companion breed today; the work is history.

Primary game

FCI 80/81/82 history: bred to guard carriages and keep stables free from rodents. UKC: initially used as stable ratters. AKC page: coachmen kept small terrier-type dogs to keep down rats in their stables.

Breed clubFCI-Standards N 80 Griffon Bruxellois, 2003

History only, not a current use. Wikipedia and the RKC say the same.

Field trial standard

FCI 80/81/82: Group 9 Companion and Toy Dogs, Section 3 Small Belgian Dogs, without working trial. AKC page: many excel in obedience, agility and tracking.

How common the problems are

Evaluated dogs skew toward breeding stock; the numbers are still the best there are.

Hip dysplasia

58.1% · 227 OFA hip evaluations, current all-data, accessed Oct 9 2026; 58.1% dysplastic (mild 39.2, moderate 12.3, severe 6.6), 38.8% normal. OFA rank 4.

MeasuredOrthopedic Foundation for Animals

OFA's own breed statistics. OFA-evaluated dogs skew toward breeding stock (owners and breeders submit films, and poor results are less likely to be submitted), so this is not the rate across all dogs of the breed; the true population rate is not known. OFA rank 1 = highest rate among the breeds listed. The sample is small (227) and for a toy breed an OFA hip evaluation is often voluntary, so the figure is a registry reading. The AKC page lists hip dysplasia among the screens responsible breeders do.

Most common disorders

Freeman et al. 2014 (84 AKC-registered American Brussels Griffons, prospective MRI study): Chiari-like malformation present in 65% and syringomyelia in 52%; 28% had neurologic deficits and 20% neck pain; 52% of dogs with syringomyelia were clinically normal. ABGA (parent club): a few health concerns are more predominant in the breed; syringomyelia has its own section; recommended tests are the CHIC breeder requirements. AKC breed page: heart problems, eye defects such as cataracts, patellar luxation and hip dysplasia; breathing problems in hot or humid weather; usually snore. RKC: Breed Watch category 2; brachycephalic (breathing difficulty, tooth crowding). Wikipedia: syringomyelia and Chiari-like malformation, eye lacerations, lens luxation, glaucoma, cataracts, cleft palate.

StudiedFreeman A.C., 2014

The Freeman cohort was recruited for the study from AKC-registered dogs, so it is not a random sample; the paper is the measured source. Wikipedia's other disorders rest on references that were not opened.

How to read this page

Every value carries a label. Measured means peer-reviewed data on many dogs. Studied means peer-reviewed, smaller or indirect. Breed club means a club or registry states it. Editorial means expert opinion with no measurement behind it. Where two good sources disagree, both are shown and neither is averaged.

Published when the entry rests on the best information available from no fewer than three independent sources, checked by a second pass that did not write it. 8 sources on this page. Found something wrong? Tell us and the correction is logged with its date.
