It’s often funny how it comes as such a nice surprise to riders that an educated horse can respond so well without metal in it’s mouth. I think we forget sometimes that we tend to “nag” a bit when a horse is bridled, and don’t when we ride bitless. I think the horse feels both physically and emotionally better without that horrid metal thing in it’s mouth, which tends to translate to a more relaxed body, and more in sync with the rider on it’s back.
A bit isn’t used to move a horse forward, which is why bitless is a very accepted method of riding in endurance; it is more of a “brakes” object used on the sensitive areas of the mouth, but when riding bitless one relies more on the pressure of the head collar on the sensitive areas of the face (above the nose, under the jaw) for the “whoa” power. So is it safe? Well, personally, I think it is very safe. I’ve found face pressure to be easier for the horse to “listen to” than mouth pressure, and even my hard headed endurance horse was more biddable in a simple halter/bridle than in a bitted bridle. I know of a few people that foxhunt in a bitless bridle, if that says anything to ya. :lol: I hunted with double reins - one set to just the rings on my “foxhunt traditional looking” halter/bridle; the other set of reins on the Waterford bit my horse wore. 99% of the time he was perfect with just the halter reins. It was rare I had to use the bit reins, but they were there in case I needed them.
Then again, foxhunting is an extreme sport, not your average hack down the trail!
As long as you feel comfortable, just ride in a simple halter. Or if you want options, then buy an endurance halter/bridle which comes with removable bit holders. Just keep the holders attached to your bit which you can carry in your pocket so if you feel the need to use the bit, you have it ready for easy attachment to your halter for instant conversion to a full bridle. The endurance halter/bridle is much easier to use with reins attached to the side rings as well.
The photo below of me and my horse at an endurance ride, used by the AERC for a full page ad in an Arabian magazine, shows him in a simple endurance halter/bridle (not a sidepull, just a simple halter) without a bit.
