The Lands of Near-Rhûn surrounding the great Inland Sea, were home to a large but good-natured breed of wild Swine (kh."Gamil-Barathgalât" Ul."Bhoishu").These hulks provided meat and hides and sometimes even served as beasts of burden to the Dwarves and Easterlings who rose them, but only the Dwarves of the Iron Hills knew how to train these beasts as loyal mounts.

Commentary[]
Tolkien's Books never mention any Dwarves riding Goats or Pigs, however dwarves riding small Horses and chamois are a traditional part of the alpine myths and fairy tales.Riding Pigs is a symbolism usually linked to celtic and norse deities such as Arduinna, Freya or Freyr.
