Greenguard Grazing Muzzle – Fitting Guide


Greenguard grazing muzzles offer a simple solution to reducing grass intake in order to ensure effective weight management. They have been designed in conjunction with vets to provide effective grazing management and are ideal for horses which are good doers prone to weight gain, laminitis or other weight-related conditions, or those that need to lose condition.

The Greenguard muzzle is unique in design, allowing unrestricted breathing and drinking while enabling a little and often grazing habit. It is easy to attach and is highly durable, as well as UV resistant. It is made from safe, pliable food-grade material. Unlike some other grazing muzzles, the Greenguard will help to keep your horse comfortable without sweating, keeping your horse comfortable and preventing rubs to the muzzle.

How to fit the Greenguard grazing muzzle

The Greenguard grazing muzzle comes fully assembled. It can be attached to a Greenguard headcollar, or to a normal headcollar with the plastic strap provided. We would recommend using either a Greenguard headcollar or a breakaway headcollar with the Greenguard muzzle for additional safety. It’s important for the headcollar to be well-fitting – not too tight or too loose – to prevent the headcollar from rubbing or from coming off.

If using your own headcollar, attach the plastic strap to the noseband of the headcollar by looping it over and pushing the toggle back through the slot (follow the drawing in the booklet provided with the muzzle)

Position the Greenguard grazing muzzle so that the "Greenguard" logo faces forwards. There should be 3 slots going across the front.

Attach the front strap to the ring on the Greenguard headcollar noseband/plastic loop. Attach the back strap to the back of the noseband (not the lead ring). Attach the side straps to the noseband or eyelets so that the straps hang perpendicular to the noseband.

Adjust the straps so that there's about 1 inch of space between the muzzle and the horse's mouth (1/2 an inch for the small muzzle). Ensure straps are not tightly connected or pulling inward on the muzzle. The muzzle should move freely when attached to the headcollar.

Adjust the strap lengths and placement so that the bottom of the muzzle is parallel to the horse's grazing surface.


Additional Tips for Fitting/Securing the Greenguard Muzzle

  • Once properly fitted, cut any excess length from the straps and use tape to secure the muzzle to prevent catching and to stop "helpful" horses from unbuckling them!

  • The straps have been designed to break away for safety - additional straps can be purchased here; baling twine or zip ties work well as a temporary fix.

  • The Greenguard grazing muzzle fits much larger than a traditional grazing muzzle - if it's too small the horse's nose/chin may hit the sides of the muzzle when opening his/her mouth to graze.

  • Tight straps or insufficient space at the bottom of the muzzle makes grazing difficult and can cause rubbing and/or the muzzle to warp or break.

  • Houdini horse? Use baling twine to attach the corners of the muzzle to the headcollar to help prevent your horse getting the muzzle off.

  • It's recommended that you introduce your horse to the Greenguard grazing muzzle gradually, bulding up the wear time slowly. It will take a short time for the horse to learn how to use the Greenguard muzzle, so it may be beneficial to push grass through the slots to help your horse or pony to understand how to eat while wearing the muzzle.

  • Ensure that the muzzle fits into your horse's water source, and remove anything the horse could catch the muzzle on in the field

  • All grazing muzzles pose some risk of teeth wear due to the fact the horse's teeth may rub against the interior surface of the muzzle. Reduce the risk by regularly washing the muzzle to remove dirt and sand. Check your horse's front teeth on a weekly basis - if there are any signs of abnormal wear, discontinue use.
