Chinook Weight & Growth Chart
Complete weight guide with growth charts for male and female Chinooks from puppy to adult.
Chinook Weight Overview
Adult Chinooks typically weigh between 50 and 90 pounds, with males generally being larger than females. Males average 50–90 lbs while females typically weigh 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..

When Does a Chinook Stop Growing?
Expect your Chinook to reach adult height of 22–26 inches by 15–24 months. Full body maturity—including muscle development toward the 50–90 lb target—may continue until 18–30 months.
Growth is influenced by genetics, nutrition quality, and spay/neuter timing. 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 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?
Assessing your Chinook's body condition (healthy range: 50–90 lbs):
- Rib check: Run your hands along the ribcage—you should feel individual ribs under a slight fat layer
- Overhead view: A defined waist should be visible between ribs and hips
- Side profile: The abdomen should tuck upward behind the last rib
Overweight Chinooks face higher risks of Hip Dysplasia, joint problems, and shortened lifespan. As a large-sized working breed, maintaining lean body condition is especially important for longevity. Work with your vet to adjust feeding and exercise if needed.
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
Plan on 0.8–1.8 cups of premium dry food daily for your adult Chinook, divided into morning and evening meals. Given this working breed's predisposition to Hip Dysplasia, discuss dietary approaches that may help manage this risk with your vet. Males weigh 55-90 pounds, females 50-65 pounds; the breed should appear athletic and well-proportioned, built for sustained pulling and endurance work..
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.
