How to get horse to take oral medication?

You need to get this stuff inside him coz founder is serious... I hold my horses tongue out of the side of his mouth, don't let go! (they don't bite their own tongues!) and then squirt in the medication. He will get used to it and it is necessary to his good health. He won't hold it against you he's a horse not a person and you can always reward him after with a few low cal treats.
