Turnout matters. Sometimes unrestricted grazing isn’t the right fit.
For horses and ponies that need help managing grass intake, a grazing muzzle can help preserve more of the benefits of pasture turnout.
The GreenGuard Grazing Muzzle helps limit pasture intake while allowing horses to continue grazing, moving, drinking, and interacting with their herd. Its open design provides generous airflow and room around the nose and mouth, supporting a more natural grazing experience while helping owners manage access to grass.
Why GreenGuard?
-
Open, Basket-Style Design
Unlike enclosed muzzle designs, GreenGuard’s open construction allows generous airflow and space around the horse’s mouth.
-
A Different Way to Graze
The patented grid design distributes grazing openings across the muzzle, rather than relying on one small opening at the bottom.
-
Designed for Movement
Lightweight and flexible, GreenGuard is designed with everyday turnout in mind—so horses can walk, graze, drink and interact with their environment.
-
Proven Over Years of Use
GreenGuard has been used by horse owners around the world for decades, with a design focused on effective grazing management and horse comfort.

A Smarter Approach to Slowing Grazing
The unique open-grid design helps slow grass intake while allowing your horse to graze across multiple openings. Instead of concentrating grazing through one small hole, the grid creates a more open grazing experience—supporting the movement, airflow and turnout that matter to your horse.
Customizable Inserts
GG Equine offers muzzle inserts that let you adjust the grazing opening to suit your horse’s individual management needs, while also helping protect both the muzzle and your horse’s teeth from wear.

Sizing Made Simple
- Mini — Best for true miniatures.
- Pony — Designed for smaller-faced ponies.
- Horse — Fits larger ponies through warmbloods.
When in doubt, size up. GreenGuard muzzles are intentionally roomy to provide space around the nose and mouth. If your horse falls between sizes—or the muzzle and bit measurements suggest different sizes—choose the larger size.
Not sure? Use both muzzle circumference and bit size to confirm your choice.
