How do I get my pony to eat?

Just be patient and spend time with him, letting him know that you love him and want him to get better...and consider his environment...maybe he is separated from his girlfriend, or lonely...consider getting a companion, that should perk him up...and it could be a donkey or a horse or a lamb...anything that is of a nice personality...and keep up the bran mash, try it warm and add apple.
