Canadian Inuit dogs are one of 12 distinct breeds known as sled dogs. The strongest teams of sled dogs are capable of pulling well over a ton in weight.
Over the course of thousands of years, humans have trained and bred dogs into the fastest, strongest, and strangest canines on the planet. Travel the globe, from the Arabian Desert to Arctic extremes to the coasts of Newfoundland, and discover the surprising journey of these pets and how they've evolved to change the course of human history.
