Briard Growth Chart
The Briard is a big, shaggy French herding dog with a heart of gold — a powerful guardian of flocks and family with a long, wavy coat and famously expressive eyebrows. Loyal and protective, Briards bond deeply with their people. Most reach an adult weight of 55-100 lb between 14 and 18 months.

Briard weight by age
Typical male and female puppy weight ranges by age, available in lb and kg. Individual puppies may vary.
Most Briard puppies approach adult weight around 18 months, although individuals may finish earlier or later.
These estimated ranges combine the breed's adult weights with a size-based growth curve. They are not measured breed-specific percentiles or health targets. Month labels are rounded approximations; use the week values for each row. How these weight ranges are calculated
Briard Growth Stages
Understanding the typical growth stages helps you know what to expect as your Briard puppy grows.
Neonatal
0–2 weeksPuppies are born with eyes and ears closed, relying entirely on their mother. Rapid weight gain occurs during this period.
Socialization
3–12 weeksEyes and ears open. Puppies begin to explore, play, and learn social behaviors. This is a critical period for development.
Juvenile
3–8 monthsRapid growth continues. Puppies become more independent, start teething, and develop coordination.
Adolescent
8–14 monthsGrowth rate begins to slow. Puppies reach sexual maturity and may test boundaries. Muscle mass develops.
Young Adult
14–18 monthsGrowth is nearly complete. Your puppy is filling out and approaching adult proportions.
Adult
18+ monthsYour puppy has reached their full adult size. Weight should remain relatively stable with proper nutrition.
Briard FAQ
How much will my Briard puppy weigh as an adult?
Adult Briards typically weigh between 55 and 100 lb. The breed standard does not split this range by sex, so both males and females fall in the same 55-100 lb band.
At what age is a Briard fully grown?
Most reach adult weight between 14 and 18 months, and big males can keep filling out into their second year. Don't expect the finished look at twelve months.
How accurate is a Briard puppy weight chart?
It is a helpful guide, but the 55-100 lb adult band is very wide — bloodline and sex make a big difference here. Track your own puppy's trend over several weeks rather than comparing to a single week's number.
How much should a Briard puppy weigh at 12 weeks?
Check the 12-week row in the weight-by-age table above for the estimated range. If your puppy falls well outside that band, re-check the scale, the lb/kg setting, and the age entry first — a single off reading is more common than a truly unusual puppy.
Do male and female Briards grow differently?
The official adult range is the same for both sexes at 55-100 lb. Males often land toward the heavier end, but the overlap is wide enough that one chart serves both well.
