The Brussels Griffon typically weighs 3.5-6 kg, stands 18-25 cm, and lives 12-15 years.

Consider this breed if…

you work from home or someone is around most of the day,
you want a small, expressive shadow that lives glued to you,
you live in an apartment - it is genuinely well suited to one,
you can keep up with dental care and face cleaning.

Do not consider this breed if…

the dog would regularly be alone for a full workday - separation anxiety is common,
you have toddlers; a 4 kg dog is easily hurt and knows it,
you want a robust dog for long hikes in summer heat,
you are not prepared for potential breathing and dental vet bills.

Frequently asked questions

How much does a Brussels Griffon cost?
A well-bred puppy in the US typically runs $2,000-$4,000 - the breed is uncommon and litters are small. Then plan for the lifetime bill: routine dental cleanings under anesthesia, possible knee or airway surgery, and 12-15 years of vet care usually cost several times the purchase price.
Can a Brussels Griffon be left alone?
Short stretches, yes; a full workday, usually not. This is a velcro breed bred purely for companionship, and separation anxiety with barking or destructive chewing is one of its most common behavior problems. It fits homes where someone is around most of the day.
Do Brussels Griffons have breathing problems?
The shortened muzzle means many Griffons snore, snort, and tolerate heat and hard exercise poorly, and some need airway surgery. Rough-coated dogs from breeders who select for more moderate heads tend to breathe better. Take heat seriously in summer regardless.
Smooth or rough coat - what is the difference?
Same dog, different upkeep. The rough coat does not shed much but needs regular brushing and stripping or clipping every few months; the smooth (Petit Brabancon) sheds moderately and needs only occasional brushing. Temperament is identical, so choose by grooming tolerance.
