Nash trains his skating skill just like all of the other sled dogs do. He gets out on the ice, attaches a few humans to the sled and starts skating. When the humans have had enough and Nash needs to up the energy level, he has the facility manager get the zamobni out on the ice and nash just goes wild and starts pulling it all around the arena making sure that he gets fresh ice for every lap that he is out there. After that he works on his balance. Normally Nash is a 4 legged warrior, but on the ice he only gets to use his two back legs to keep his balance. Even though he's been playing hockey since he was young, it still takes a little bit more effort than a regular human who is always walking on two legs. Just getting in the right mindset is half the battle for this dog warrior.
