I have a 10-year-old Arab gelding who's new to my place - he's been here about a month. He's a real pleasure to ride, has a LOT of go AND is pretty level-headed in the scheme of things.

He has a habit of head tossing. I think it's just part of how he plays, he does it all the time in the field, too. Throws his nose straight up in the air, shakes it around a bit as it's coming down, tosses it once or twice before moving on. However, while it's funny to watch in the field, I'm less appreciative when he does it under saddle.

His previous owner rode him with a running martingale and that does help him keep his head down. However, I'd prefer not to use it, and he and I are both happier riding with a loose rein. Any other ideas?

He's in an egg-butt snaffle, FWIW. Other than this little foible he's a really good guy.
