you could also watch the movie how to tame your dragon to learn how to do this but i am not sure if you will go through the 2 hrs movie to understand that and then you will be interested to watch the second part since the first part only covers how to tame but the second part also deal with how to control all the dragons in the world be it ice be it fire all will listen to my command and ti will be so much fun to see them dance to my tunes and rip the head of all the soldier that are trying to get me angry. Each dragon has a different way of taming so obviously you need to specialize in one and this one will be the ice dragon and i know how the best way is and to know how to do this you will have to read the book -- How to Tame your Dragon in Infinity Days.. once you read through please let me know and then i can show you how the book is practically implemented on the Ice Dragons.
