Chinooks are medium to large-sized dogs, typically standing between 20 to 27 inches (51 to 69 cm) tall at the shoulder. Their weight generally ranges from 45 to 90 pounds (20 to 41 kg), with males usually being larger than females. They have a strong, athletic build suited for endurance.

Chinooks are known for their friendly, gentle, and energetic nature. They are typically good-natured and sociable, getting along well with children and other pets. They are intelligent dogs that thrive on positive reinforcement and consistent training. Early socialization is important to help them develop into well-rounded companions.

Chinooks have a thick double coat that is designed to insulate them against cold weather. The outer coat is medium-length and may be straight or slightly wavy, while the undercoat is soft and dense. Coat colors can vary, including shades of gold, tan, and red, often with a darker mask or markings. Regular grooming is necessary to manage shedding, particularly during seasonal changes.

Chinooks thrive in active households and can adapt to different living environments, including homes with yards and rural settings. They are not suited for apartment living unless they receive sufficient daily exercise. They enjoy being part of family activities and can develop separation anxiety if left alone for extended periods.

Chinooks require regular exercise to stay healthy and happy. Daily walks, runs, and play sessions are essential for their well-being. They enjoy activities that involve running, such as hiking and jogging. Additionally, Chinooks are strong swimmers and may enjoy water-related activities. Engaging them in obedience training, agility, or dog sports can also provide mental stimulation and physical challenges.
