Chinook Weight & Growth Chart
Complete weight guide with growth charts for male and female Chinooks from puppy to adult.
The Chinook belongs to the Working group and originates from United States. Adults typically weigh between 50 and 90 pounds, standing 22 to 26 inches at the shoulder. Life expectancy runs from 12 to 15 years, and the figures on this page describe that range rather than a single average, because the spread is what matters when you are deciding. Running costs settle around $185 a month once the dog is past puppyhood, before insurance and before anything unexpected. These numbers come from published breed standards and, where a standard is silent, from longevity and veterinary studies; they describe the breed as a population and not the dog in front of you. Line, upbringing, early socialisation and simple chance move an individual well away from the typical profile, and two dogs of the same breed often differ more than two dogs of different breeds. Nothing here is a diagnosis: for a specific animal, a veterinary surgeon who has examined it will always know more than a table.
Chinook Weight Overview
Weight range for the Chinook: 50–90 lbs overall. Males: 50–90 lbs. Females: 42–79 lbs.
Males weigh 55-90 pounds, females 50-65 pounds; the breed should appear athletic and well-proportioned, built for sustained pulling and endurance work.. Consult the growth chart below for typical weight progression by age.

When Does a Chinook Stop Growing?
Chinooks typically reach their full adult height of 22–26 inches by 15 to 24 months and their full adult weight of 50–90 lbs shortly after. Males weigh 55-90 pounds, females 50-65 pounds; the breed should appear athletic and well-proportioned, built for sustained pulling and endurance work..
Factors that influence growth include genetics, nutrition, and spay/neuter timing. For this working breed, a large-breed puppy food with controlled calcium is recommended to support proper joint development.
Chinook Male vs Female Size Differences
Male and female Chinooks differ noticeably in size, a pattern common in large breeds. Males typically weigh 50–90 lbs, while females weigh 42–79 lbs. Both sexes stand 22–26 inches tall at the shoulder, though males tend to fall at the upper end of this range.
These size differences can influence practical ownership decisions. Larger males require more food, larger crate sizes, and stronger leash handling. Female Chinooks at the lower weight range may be easier to manage physically for smaller handlers or families with children. Both sexes share the same temperament and health profile, so size preference should be a practical decision rather than a temperament-based one.
Is My Chinook Overweight?
Is your Chinook at a healthy weight? The ideal range is 50–90 lbs (males 50–90, females 42–79). Check these three signs:
- Ribs: Easily felt with light pressure; not visible but not buried under fat
- Waistline: A clear narrowing behind the ribs when viewed from above
- Abdominal tuck: The belly slopes upward from the ribcage to the hind legs when viewed from the side
If your dog fails any of these checks, consult your vet. The small gene pool from near-extinction events means genetic diversity is a concern; responsible breeders use genetic testing to maintain health and diversity..
Chinook Weight Management Tips
Maintaining your Chinook at a healthy weight between 50 and 90 lbs is one of the most impactful things you can do for their long-term health. Studies consistently show that lean dogs live an average of 1.8–2.5 years longer than overweight dogs of the same breed.
Portion control: Use a measuring cup for every meal rather than estimating. Feed the amount recommended for your Chinook's ideal weight, not their current weight if they are overweight. Divide daily food into two meals for adults and three meals for puppies under six months.
Treat management: Treats should not exceed 10% of daily caloric intake. Use small, low-calorie training treats and consider using pieces of your dog's regular kibble as rewards during training sessions. Avoid table scraps entirely, as they add unpredictable calories and can introduce foods that are toxic to dogs.
Exercise alignment: With an exercise needs rating of 3/5, the Chinook requires moderate daily exercise. Balance food intake with activity level, adjusting portions during periods of reduced activity such as recovery from illness or injury.
Regular weigh-ins: Weigh your Chinook monthly and track the trend. Gradual weight gain of even one to two pounds per month can lead to significant obesity over time. Your veterinarian can establish your dog's ideal weight during wellness visits and recommend caloric adjustments as needed.
Feeding Recommendation
An adult Chinook's daily food intake is typically 0.8–1.8 cups of high-quality kibble, fed in two meals. Males weigh 55-90 pounds, females 50-65 pounds; the breed should appear athletic and well-proportioned, built for sustained pulling and endurance work.. At 50–90 lbs with energy level 3/5, a joint-supporting formula is recommended for this large-sized working breed.
Chinook Weight by Age Table
The following table shows expected weight ranges for male and female Chinooks at key developmental milestones. Individual dogs may fall slightly outside these ranges depending on genetics, nutrition, and activity level. Consult your veterinarian if your Chinook's weight deviates significantly from these benchmarks.
| Age | Male (lbs) | Female (lbs) |
|---|---|---|
| 3 months | 16.1–19.9 | 13.7–16.9 |
| 6 months | 36.3–44.7 | 30.8–38.1 |
| 9 months | 52.4–64.6 | 44.5–55.0 |
| 12 months | 64.5–79.5 | 54.7–67.7 |
| 18 months | 76.6–94.4 | 65.0–80.4 |
| 24 months | 80.6–99.4 | 68.4–84.6 |
Health Risks of Incorrect Weight in Chinooks
Both underweight and overweight conditions pose serious health risks for the Chinook. Understanding these risks reinforces the importance of maintaining your dog within the 50–90 lb target range.
Overweight risks: Excess weight places additional strain on joints, increasing the risk and severity of conditions like Hip Dysplasia. Overweight Chinooks also face higher rates of diabetes, heart disease, respiratory compromise, heat intolerance, and reduced lifespan. Even moderate excess weight, just 10–15% above ideal, shortens life expectancy and reduces quality of life.
Underweight risks: A Chinook consistently below 50 lbs may be experiencing inadequate nutrition, parasitic infection, dental problems that prevent eating, or underlying illness. Underweight dogs have weakened immune systems, poor coat quality, reduced energy, and slower healing. If your Chinook appears thin despite normal feeding, veterinary examination is essential to rule out medical causes.
