20. Chinook

The Chinook is a powerful working dog developed in the United States for sledding and transport. Males weigh up to 90 pounds and stand 26 inches tall. They are loyal, patient, intelligent, and easy to train. Created in New Hampshire by Arthur Treadwell Walden, Chinooks combine the endurance of sled dogs with mastiff strength. Their tawny coats and friendly personalities make them stand out. Chinooks are gentle with family, especially children, and thrive on regular exercise and mental stimulation. Their eagerness to please and intelligence make them highly trainable and excellent companions.
