In the old days, this was such a staging area. This was where the race started. Today most mushers go hundreds of miles down the trail from Rohn before stopping. Some of the dogs were stressed by daytime temperatures in the 30s, although most mushers were resting during the heat of the day. The IV treatments are relatively new for the Iditarod dogs.
Vets say they help dehydrated dogs perk up and recover faster.
Unlike participants in some human sports, however, dogs that get IVs can't go on.
