GreenGuard Grazing Muzzle (Muzzle Only)
Comfort, safety, and smart design—trusted by horse owners worldwide.
The GreenGuard Grazing Muzzle is designed to be the most comfortable and effective way to manage your horse’s grass intake. Unlike traditional basket muzzles, its patented open design allows for free breathing, easy drinking, and better airflow, keeping your horse cooler and happier.
Crafted from a non-toxic, semi-flexible, and moisture-resistant material, the GreenGuard muzzle is lightweight, durable, and long-lasting—horses are far less likely to rub, resist, or destroy it compared to conventional designs.
Each muzzle includes four breakaway safety straps that easily attach to a standard halter (we recommend using a safety halter). For the best fit and performance, pair it with the GreenGuard Breakaway Halter—featuring a ring on the noseband for quick attachment, a center face strap for stability, and soft padding on the nose and crown.
Please note: This listing is for the muzzle only. GreenGuard Breakaway Halter sold separately.
