    Which is the right size?

    GreenGuard muzzle sizing is based on your horse's nose circumference and bit size. See our complete muzzle sizing guide.

    You can also watch a full and detailed walkthrough video on our YouTube channel.

    How to connect the straps?

    As a rule, the muzzle is angled properly when the front strap is longer, and the rear strap (behind the chin) is very short for size 5 (horse) and Size 4 (pony). For size 3 (mini) the straps tend to be more or less the same length.

    Here's our best practices video for our leather breakaway straps. It includes our recommendation to cinch them down with electrical tape. Loopy straps can get caught on things and breakaway prematurely!

    Will it work with my horse's halter?
    • The GreenGuard muzzle is compatible with just about any halter you've ever tried. It's just a matter of finding the right connection points, keeping the muzzle from sliding, and using a breakaway safety halter. Here's our tutorial on attaching a GreenGuard muzzle to a standard halter.
    • You can also convert any halter into a GG-style halter - with a center face strap - by using our fleece converter set. The fleece helps prevent rubs while the center strap provides an anchor for the front muzzle strap.
    Prevent and Manage Rubs

    Here is our general tutorial covering all of the major causes and solutions for muzzle and halter rubs.

    Nose and Chin Rubbing:

    Our Muzzle Rub Protector Stickers adhere to the muzzle panel to prevent chafing and rubbing, or you can DIY this option using smooth tape (our preference is gorilla tape).

    Have a draft or draft cross whose mouth is just a little too big for the Size 5 (Horse) muzzle? We have a DIY procedure for expanding the back panel. Note: it will void your warranty, so reach out with any questions.

    Jaw Rubbing:

    If your horse is developing a rub under their jaw area between their chin & cheek bones, we have a video about treating jaw rubbing.

    Can i cover muzzle holes?

    Our leather muzzle inserts are useful, not only in extending muzzle life and being gentler on horse teeth, but also for aiding in grass restriction. We've developed two approaches to additionally restrict or further customize grass intake.

    1. Customize the size of the holes to restrict grass intake
    2. Temporarily block all holes for a medical reason/procedure or farrier visit
    Muzzles and Tooth Wear

    According to the National Equine Welfare Council's "Grazing Muzzle Guidance," all grazing muzzles carry a risk of tooth wear. The NEWC recommends your horse get at least an annual check by an equine vet or dental specialist.

    This video addresses everything we know to date about preventive measures and solutions for tooth care while using a grazing muzzle.

    We highly recommend cleaning your GreenGuard muzzle and checking your horse's teeth regularly when they are wearing a muzzle.

    Finally, leather and rubber muzzle inserts have been designed to prolong the life of your muzzle and to wear faster and be gentler on horse teeth. If you horse has existing tooth wear, we recommend the leather insert.

    How much do muzzles restrict grass intake?

    According to the National Equine Welfare Council's "Grazing Muzzle Guidance," "grazing muzzles can reduce grass intake by up to 80%." (skip to 4:24 in the video link for the exact quote)

    In practice, real grass restriction depends on a number of factors: the grazing muzzle, the horse that is wearing it, how long the grass is, and how practiced the horse is at grazing in a muzzle, among others.

    What is undeniable is that horses in grazing muzzles get more exercise than horses in stalls or in dry lots. A turned-out, muzzled horse gets less grass and more exercise, both of which contribute to weight management.

    If your horse requires further grass restriction than the muzzle alone, there are solutions. Muzzle inserts cover an additional 30% (leather) to 50% (diet) of the available grazing area.

    We have also developed methods for further customizing the size of the GreenGuard muzzle holes or temporarily blocking all holes for a medical reason/procedure or farrier visit.

    You can read more details about the muzzle and insert restrictions, and the best way to monitor weight on our blog post, "How much do muzzles restrict intake?"

    Is there a "Diet" insert for the mini muzzle?

    The mini leather insert blocks part of the muzzle holes right down the center, making the muzzle holes about 30% smaller (see photo below).

    Because of the mini muzzle's unique curvature, they typically aren't able to graze through the outer edges very well, so their actual open grazing area is quite small with the leather insert. The leather insert also makes the muzzle grazing surface much thicker. Most owners find that the leather insert provides the right amount of restriction and is comparable to the diet inserts in the other two sizes even though it doesn't look as restrictive.

    While you can customize the size of the mini muzzle's holes, we do not recommend doing this unless you have been advised by a vet or nutritionist that they need this level of grass restriction.

    Donkey diet

    I got a greenguard muzzle for my donkey. I was worried that she would try to get It off, but she’s had it about a month now and it’s still on and she’s losing weight! No big rubs so far, however, I suspect I’ll have to pad things up mostly just from wearing the halter all the time.

    Dee, thank you so much for taking the time to share your experience with the muzzle! We'd love to see a photo of your donkey if you have one to send along. What's her name? If either of you ever run into any issues, if you start to notice any halter rubs, or either you or she has any questions, please reach out to We're here to help both of you every step of the way in your muzzle journey!

    A Grazing Muzzle my mare is finally okay with!

    I have tried other grazing muzzles, and although they have worked well, in the summer they would make my mare's face sweaty and it was hard to clean. The GreenGuard is the only one she will actually put her head down for and not give me that "look". The ventilation is great and it's easy to clean--just a rinse. The straps make it easy to adjust for a good and comfortable fit.

    Janet, thank you so much for your thoughtful and detailed review of the GreenGuard muzzle. The fact that your mare isn't giving you 'the look' is as close to a rave as we get from most horses, and we treasure that feedback. The comfort, airflow, and coolness of the muzzle body really does make a difference, especially during relentlessly hot summers like this one. If you or your mare ever has any questions or concerns, or if you'd like to share a photo of your mare and a progress report of how she's getting on with the muzzle, please reach out to We're here for you both, every step of your muzzle journey.

    Lighter, cooler than other grazing muzzles!

    My mini donkeys wear these lightweight, cooler grazing muzzles and they work great! The other grazing muzzles we had before these were much heavier and hotter for my mini donkeys to endure in the hot summer months. These GG Equine halters and grazing muzzles stay in place and have slowed their grass intake which is the goal. Very happy with the quality and functionality of these halters and grazing muzzles!

    Darci, thank you for your thorough and enthusiastic review of the GreenGuard muzzles and GG halters. We are overjoyed that your mini donkeys have adapted so well to the whole set up. We know muzzling can be difficult, so we try, through all our products, to emphasize the comfort of the animals who wear them, starting with the muzzle itself. We're glad to offer alternatives to nylon and canvas muzzles that your mini donks can graze more easily in. We'd love to see photos of them if you have any to share! Thanks again, and if you or the mini donkeys ever have any questions, just send a note to We're here to help.

    horse took right to it

    My horse used to fight me to put on a grazing muzzle, this one I have attached to an extra halter and he lets me put it right on.

    Stacy, we are so glad to hear your horse has accepted the GreenGuard Grazing Muzzle. We know that muzzling can be difficult for horses to get used to, so to know he's tolerating this one is a huge step and relief for everyone. If either you or he ever has any questions or issues, please reach out to We're here to help you both along your muzzle journey.

    Best Muzzle

    We are loving this muzzle. Stays on and allows plenty of airflow so you don’t have to worry about the horse or mule having affected breathing. Seems to hold up nicely too

    Tara, thank you so much for leaving a review! Airflow makes a massive difference to an animal's comfort, especially during summers like this one. If you ever have any questions or concerns, don't hesitate to reach out to
