Chinook Growth Chart
The Chinook is a rare American sled dog from New Hampshire, bred for drafting power rather than racing speed. Calm, gentle, and strong, Chinooks are large working dogs with a broad chest and tawny coat. Most reach an adult weight of 50-90 lb between 14 and 18 months.

Chinook weight by age
Typical male and female puppy weight ranges by age, available in lb and kg. Individual puppies may vary.
Most Chinook 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
Chinook Growth Stages
Understanding the typical growth stages helps you know what to expect as your Chinook 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.
Chinook FAQ
How much will my Chinook puppy weigh as an adult?
Adult Chinooks typically weigh between 50 and 90 lb — one of the widest ranges in the large category. The breed standard does not split this range by sex, so males and females share the same 50-90 lb band, with males tending toward the heavier end.
At what age is a Chinook fully grown?
Most reach adult weight between 14 and 18 months. Draft-bred sled dogs grow unevenly — long legs first, chest and shoulders later — so a rangy adolescent is usually right on schedule.
How accurate is a Chinook puppy weight chart?
It is a reasonable guide, but the breed's range is unusually wide and bloodlines vary. Weigh monthly and watch the multi-week trend; a puppy tracking the same growth line is doing well even if it sits high or low in the band.
How much should a Chinook 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 Chinooks grow differently?
The official adult range is the same for both sexes at 50-90 lb. Males tend toward the heavier end of the band, but the overlap is wide enough that one chart serves both.
