My opinion is that all of the dogs should get credit because, Balto ( the dog) wasn't the only one who was riding the Iditarod and Togo did run 350 miles, but, all of the dogs tried their best and they worked together. The mushers also fell into hard times and they all did their part so the other dogs and mushers should have credit!!
In fact, if Balto and Togo couldn't make the race, the mushers would try to get them going, because children were getting sick and dogs had to do it so if another dog team were in this situation, they would have to go, because of all the people getting sick in Nome, Alaska !! All the dogs have to be honored and, just because Balto was first, it doesn't mean that he should be honored!!
All of the dogs volunteered and they were determined, brave and also were very careful not to keep the serum from freezing!! But, the serum did freeze but, the effect was still the same, so all of the sick people in Nome were getting better, thanks to all of the dogs and mushers who participated in the Iditarod!!
