Anyone have any suggestions to get a too smart for his own good horse to take a bit? We've tried using a rope first so it doesn't bang his teeth, which he takes eventually but after a huge struggle. We've tried putting apple syrup and peppermint on the bit but he just licks it off and clamps his teeth shut as soon as we try to put it in his mouth. What's weird, though, is the very first time we introduced him to the bit he took it like he's been doing it for years, and spat it out fine without it hitting his teeth, but we can't get him to take it again! Please help!
EDIT - His teeth are fine, and he doesn't have wolf teeth so nothing is uncomfortable for him
