Somewhat missable cheev.
When you make an attack on Galbadia Garden, you will work your way inside to the centre of the garden. There will be a three headed hound with a massive tail. Simply approach and interact with it and win the battle.
Alternatively if you want to avoid the battle, or you have missed Cerberus, it can be drawn from Gargantua in the final dungeon during ultamicas castle
