Growth Chart

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..

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.

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..

Frequently Asked Questions

Adult Chinooks weigh 50–90 lbs (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..
Most Chinooks reach adult height of 22–26 inches by 15–24 months, with full body weight of 50–90 lbs achieved 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..
Three quick checks for your Chinook: (1) Feel the ribs–they should be easily palpable under a thin fat layer. (2) View from above–there should be a visible waist behind the ribs. (3) Side profile–the abdomen should tuck up. Target weight: 50–90 lbs. Their coat type allows for relatively easy visual body condition assessment. Consult your vet for a body condition score.
Feeding amounts depend on age, current weight, and the Chinook's expected adult size of 50–90 lbs. Puppies under 6 months need 3–4 meals daily; older puppies eat twice daily. For this large-sized breed, a large-breed puppy formula helps control growth rate and protect developing joints. The small gene pool from near-extinction events means genetic diversity is a concern; responsible breeders use genetic testing to maintain health and diversity..
A Chinook puppy not gaining weight needs veterinary attention. Expected growth milestones lead to an adult weight of 50–90 lbs (males 50–90, females 42–79). Possible causes: parasites, insufficient calorie density in food, stress, or underlying conditions. Ensure the puppy is eating without competition from littermates or other pets.
