He had a brother named Nori who became a thief, and this had made Dori resent his younger brother. Next was his other brother, Ori who he had later mothered and fathered all his life.

An Unexpected Journey
Dori was one of the dwarves that had fallen on Bilbo's doormat. He was a decent fellow despite his grumbling, offering Gandalf a spot of tea, and later red wine. Dori objected that his younger brother Ori cried out that he will give Smaug a "taste of the Dwarfish iron right up his jacksie". On the road, Dori asked Gandalf if he could stop the rain storm, but Gandalf retorts that he'll have to find another wizard to change the weather of the world.

He was on a spit when the dwarves attempted to rescue Bilbo from the trolls, and begged Bilbo not to reason with them because they were half-wits. Ori refused to eat his green food, and to no avail, Dori cannot convince Ori to eat the food on his plate. When Thorin and his twelve companions are captured by Goblins that live in the Misty Mountains, Dori finds out his brother had stolen things from Rivendell, which his brother said they were "for a couple of keepsakes". Later, one of the dwarves blame Dori for not taking care of their hobbit, when he said it's not his fault Bilbo is gone.

During the attack of the Wargs, Dori and Ori nearly fall off the tree they and their companions are on. However, Gandalf uses his staff for them to grab onto. Dori loses his grasp while Bilbo saved Thorin's life, but he and Ori are caught by the eagles and are flown to safety to the Carrock.
