Leave approximately one inch between the horse's mouth and the inside of the base of the muzzle. The Deluxe muzzle has a roomy fit to allow for chewing. You should be able to fit two to three fingers sideways between your horse's face and the muzzle. This is our most popular design because it is so easy to use and costs less than purchasing a separate breakaway halter. Please be aware that you need to spend a few days - or even weeks in some cases - training your horse to become accustomed to wearing the muzzle. Full details come with each muzzle for correct training. Horses very quickly adapt, once they realise that they can still eat! Do not attempt to leave the muzzle on the horse without training him Home Page | Standard Muzzle Sizing
