Old Doug is a pet Orangutan in Age of Empires III: The Asian Dynasties.

He is one one the strongest Pets in the game, and also, one of the most easily encountered in Asian Dynasties; they can be trained in Wokou Junks and Marathan Catamarans, for 200 food.

In Ceylon (where the player begins with a Catamaran) and Borneo, they can make a substantial difference in treasure-hunting. Should the player have plenty of food in the early game, it might not be a bad idea to train one or two.
