ANCHORAGE (KTUU) - On average, 30 percent of the dogs that compete in the Iditarod won't be able to complete the grueling race.
When a dog becomes injured or fatigued, it's transported to one of four hubs — McGrath, Unalakleet, Nome and eventually Anchorage.
The Iditarod headquarters in Anchorage is the Lakefront Anchorage, where veterinarian Erika Friedrich has been in charge of return dog care for 6 years.
Veterinarians and technicians are on staff at each location 24/7 to ensure that dogs in need of medical care are treated. They also ensure that each dog is in good health before it's allowed to return to a musher or handler's care.
