These young pups on Herbert Island, Greenland, will grow up to be powerful, thick-furred sled dogs conditioned to survive long periods of exertion in subzero temperatures. A hardy breed descended from canines that accompanied immigrants who traveled from Siberia to Greenland some 5,000 years ago, Greenland dogs pull sleds that weigh upwards of a thousand pounds (450 kilograms) in temperatures near minus 70 degrees Fahrenheit (minus 57 degrees Celsius).
