Oldies think they know best, and some will take advantage if they can. If you feed him treats by hand then I advise you not to as this can make biting worse. If he bites, say 'No!' and make him back up a couple of steps, as this is what other horses would do if he bit them. He may respond well to a slap on the shoulder, as he probably knows biting isn't ok (I assume he doesn't bite everyone? If he does then it's a bigger problem). If you see him going to bite you, gently push his head away, don't hit him. Or try doing a little, quick star jump (don't lift your arms too high, just away from you a little) as the sharp movement usually makes horses back off. One youngster I know will ignore any amount of loud words or smacks, but a star jump works wonders!

Thanx, but he is my friends riding school pony , so no can do. Thank you muchly any way, though.

Thank you!!!
