The dogs are absolute heroes. The remaining team consists of Pilot, Balto, Nitro, Vampire, Slipper, Mary Jane, Beaver, Gravel, Lefty, Crosby and Nash. All still seem happy, watching Billy with intent eyes and perked up ears as he whistles his way through the chores. The tired team perks up when they hear Billy sing. He's the most amazing animal on the planet.

Billy runs to his side. The dog's front tricep muscle is cramping up. Billy massages the muscle for a half-hour, and soothes the dog with a song. There was some exposed ice on the river and he slipped a few times and bruised his shoulder. But after an eight hour rest, Pilot is on his feet with his tail wagging, ready to go.
