Summary: Hairdresser Amy, who lacks confidence when it comes to controlling her basset hound, and student dropout Tyler, who refuses to take responsibility for walking, feeding and cleaning up after his dog, leave their dogs behind and travel to Alaska to spend a week working with dogs that race sleds for a living. The Brits can barely look after their own dogs, but have to look after more than 80 dogs, making sure they are fed and kept clean. They train to enter a real race across the frozen Yukon - an event that will push them to the limit. Will the experience help them re-evaluate their own lives and become better pet owners?
