Alaska's Iditarod dogs get neon visibility harnesses after 5 were fatally hit while training

The Iditarod, the annual sled dog race celebrating Alaska's official state sport, is set to get underway Saturday with a new focus on safety after five dogs died and eight were injured in collisions with snowmobiles while training on shared, multi-use trails.

For the first time, mushers who line up for the ceremonial start in Anchorage will have the chance to snag light-up, neon harnesses or necklaces for their dogs before they begin the days-long race that takes the dog-and-human sled teams about 1,000 miles (1,600 kilometers) over Alaska’s unforgiving terrain.
