Dogi is the first guard that you will find and obtain in the game. It is unique in that it has two colors, white and pink.
The first time you will fight Dogi in a battle is at Basalon Town, in the "Fight with wild dog" quest.
Dogi is a fairly average guard stat wise in the early part of your game. He is a good normal damage attacker; he is one of the best until you get further into the game.
