20. Chinook

The Chinook is a formidable working dog crafted in the US for sledding and hauling. Males reach up to 90 pounds and 26 inches tall. Loyal, patient, and smart, they’re easy to train. Developed in New Hampshire by Arthur Treadwell Walden, Chinooks blend sled dog endurance with mastiff power. Their tawny coats and warm personalities shine. Gentle with family, especially kids, they thrive on regular activity and mental challenges. Their eagerness to please and intelligence make them exceptional, trainable companions.
