Im currently in school to be a vet tech. When they taught the class on equine restraint, they said something that I highly disagreed with. They said that a chain was to be used over the nose, under the chin, or over the gums. Take in mind the vast majority of people in this class have never worked with horses before. I have used chains at the racetrack, but never under the chin and definitely not over the gums.
Am I wrong?
