Drop nosebands are often used to help stabilise the bit in the horse’s mouth. This also helps to prevent them from opening their mouth so much and evading contact but never fit a drop noseband too tight as the purpose is not to clamp the horse’s mouth shut, but to offer stability.  You should always be able to slide a finger under the whole noseband, all the way around. Make sure you fit the drop noseband above the “fleshy” part of the nose.  It should sit on the bony part of the nose.  If you are not sure, use your hands to feel over the horse’s face until you can feel the bone so it should be around a hand width above the nostrils. If it is fitted too low there is the possibility to cause stress fractures to the nasal bones. The sides of the noseband straps should not interfere with the eyes and they should sit far enough away so that the horses’ vision will not be impaired. The drop noseband rings should not interfere with the bit rings and do not fit a standing martingale to a drop noseband as they are not designed for this use.
