Denali National Park has a huge kennel of dogs. They specifically raise and train them to WORK. In the winter time when no vehicles can travel the roads, there are still people out in the “boonies” studying the wildlife and terrain, artists-in-residence, hikers snowshoeing, etc. They have to have some way to deliver supplies and do maintenance. So they use dogs pulling sleds.

In May, they had a new bunch of sled puppies born, so now 4 months later, they were still rolly polly little balls of energy. The rangers gave a demonstration of the adults pulling a sled and the training they give them.
