University of Alaska researchers found sled dogs given a commercial meat-based food had significantly higher levels of antioxidants than animals primarily fed locally caught salmon. Dogs testing for higher levels of mercury had lower levels of antioxidants, however mercury levels for all animals fell within the safe range for humans, researchers said. The scientists hope to continue to use sled dogs as a model organism for the local human population, which also relies heavily on salmon for food.
