Strider (pony)
From Tolkien Gateway
Strider was a pony acquired by Frodo Baggins in Minas Tirith, whose name "Strider" came from Aragorn's own nickname in the northern lands. Frodo's pony was well travelled indeed: his master rode him back from Minas Tirith to the Shire after the War of the Ring,[1] and two years later he carried his master westwards to the Grey Havens on the coast of the Great Sea.[2]
