Brussels Griffon
BRUH-sulz GRIF-on
Alert, Curious, Sensitive, Self-important. Originally bred for ratting in stables; later companionship.
An adult Brussels Griffon weighs 8-10 lbs (male) or 8-10 lbs (female), needs 220-350 calories daily, and lives 12-15 yrs. As a toy breed, every calorie and every ounce of body weight matters proportionally more. The breed's primary health watch is patellar luxation. All numbers below come from AKC breed standards and NRC 2006 veterinary nutrition formulas.
Nutrition and feeding
A typical adult Brussels Griffon needs 220 to 350 calories per day. An average male (9 lbs / 4.1 kg) needs around 280 kcal; a female (9 lbs / 4.1 kg) roughly 280 kcal. These estimates use the vet-standard RER/MER formula.

Health profile
The Brussels Griffon's distinctive flat face and compact frame come with specific health trade-offs. Their brachycephalic features can contribute to breathing difficulties, and their protruding eyes are vulnerable to injury and ulcers. Awareness of these breed-specific risks helps you catch problems before they become serious. Life expectancy is 12 to 15 years.
Exercise and activity
Don't let their size fool you; Griffons have genuine stamina for short bursts. Two 15-minute walks plus some indoor play is the sweet spot. They're prone to overheating due to their flat faces, so skip outdoor exercise when it's hot and humid. Mental stimulation matters as much as physical exercise for this intelligent breed; puzzle toys and training games keep them sharp without overexerting those short airways.
Care and traits
Brussels Griffons have a rough (wiry) or smooth varieties coat. Origin: Belgium (Brussels).
The Ewok-like face from 'As Good as It Gets' boosted their popularity. Small litters and difficult births make them relatively rare. Very human-oriented dogs who don't do well alone for long periods.
Their small size makes them suitable for apartment living, but they still need daily outdoor exposure and socialization. Small dogs are vulnerable to injury from rough handling, falls from furniture, and confrontations with larger animals. Supervision around young children is essential.

Frequently asked questions
Most adult Griffons do well on 220 to 350 calories per day; the exact number depends on age, activity level, and whether they're fixed. At around 9 pounds, plan for roughly 280 kcal daily. Because they're prone to hypoglycemia, split that across 3-4 small meals rather than one or two larger ones. Use our calorie calculator to get a personalized number for your Griffon.
Both males and females typically weigh 8-10 lbs (3.6–4.5 kg).6–4.5 kg). Because Griffons are so small, even half a pound of extra weight is proportionally significant; the equivalent of a large-breed dog gaining 5 or 6 pounds. The rib check is your best friend: you should feel ribs easily with light fingertip pressure.
Health records for the breed show patellar luxation as the most prevalent concern in Brussels Griffons. Patellar luxation (kneecap slipping) and respiratory difficulties related to their flat face are also common. Heart murmurs appear in the breed more often than average. Annual vet checkups with breed-aware screening catch most issues early.
The Brussels Griffon does well with 20 to 30 minutes of daily activity. Two short walks (15 minutes each) plus some indoor playtime covers it. Griffons are moderately active but tire relatively quickly and overheat easily due to their brachycephalic face. On hot days, keep exercise indoors. They're excellent apartment dogs precisely because their exercise needs are manageable.
