Find a Dragon Scout mob - he is wandering somewhere in the plains biome. Attack him, and the hunters' camp will appear.
Hunters camp is a big group of Illagers that should be defeated. Among them, there is Dragon Wizard that will drop a Ferox Dragon spawn egg.
Use a Ferox Dragon spawn egg, and the dragon will appear - give him cod to tame.
A tamed dragon will follow you, fight on your side, and can be used as a mount.
