Harrier weight by age
Typical male and female puppy weight ranges by age, available in lb and kg. Individual puppies may vary.
Most Harrier 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
Harrier Growth Stages
Understanding the typical growth stages helps you know what to expect as your Harrier 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.
Harrier FAQ
How much will my Harrier puppy weigh as an adult?
Adult Harriers typically weigh between 45 and 60 lb. The breed standard does not split this range by sex, so males and females share the same 45-60 lb band — males tend to sit at the heavier end.
At what age is a Harrier fully grown?
Most reach adult weight between 14 and 18 months. Pack hounds build stamina before bulk, so a lean, energetic adolescent is usually still filling out.
How accurate is a Harrier puppy weight chart?
It is a good guide. Harriers are active, high-energy dogs that burn a lot of calories — an adolescent that runs hard all day may track the low end of the band without being underweight.
How much should a Harrier 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 Harriers grow differently?
The official adult range is the same for both sexes at 45-60 lb. Males may average a few pounds heavier, but the overlap is wide enough that one chart serves both.
