Ponies are mentioned 73 times in our book.  Thorin & Co. lost their original ponies in the goblin cave, had the loan of ponies for some of Chapter 7 from Beorn, they received ponies in Laketown only to have most of them eaten by Smaug.  Finally, Bilbo has a pony on which to ride home and which will carry his treasure.  Being by definition only of a certain height or less, I shall declare them “low”.

Richard Blackwelder wrote an essay on the horses of The Lord of the Rings, including a mini chapter on the ponies of The Hobbit.

“Pony” has the food tag because both goblins and Smaug like to eat them!
