A grazing muzzle is meant to restrict a horse's or pony's grass intake. They are not meant to prevent them from eating grass altogether.

Grazing muzzles are a staple in the tack room of many pony and horse owners. These muzzles fit over the mouth and nose of a horse and restrict grass intake while allowing access to pasture.

Grazing muzzles have been shown to reduce grass intake by approximately 80% in ponies which make them a good option to help keep a good doer’s waistline in check.
