Can your horse wear a martingale with a figure 8 bridle?

A figure 8 simply keeps the horses mouth closed around the bit so it cannot evade the bit. Sometimes its used simply to keep a horses tongue in its mouth when the horse likes to stick it out. (Not kidding, there are horses that prefer to keep their tongue stuck out.) A flash noseband performs the same function but some people think a figure 8 is more comfortable for the horse.

You can certainly use a martingale with a figure 8. If you use a standing martingale be sure to attach it to the part of the nose band that does not go below the bit. It must attach to the upper noseband.
